ball valve actuator

Image Source:

Ball valve actuators are part of a larger family of pneumatic actuators. They are used to control the flow of air or gasses in various industrial applications. Ball valves are valves that have a round ball-shaped disc that closes off a passageway when the valve is closed.
The disc is held in place by spring-loaded arms or other mechanisms. The ball seals against the passageway and opens only when pressure is applied to open the valve and push the ball out of its seat.

Valve automation: things to consider

Image Source:

Ball valves are one of the most common types of valves used in industrial and commercial applications, including water treatment systems. They are also used in certain home applications, such as water heaters, washing machines, and dishwashers
Ball valves are easy to install, operate and maintain. They feature a ball that seals against the valve seat when closed. The ball is lifted off its seat by rotating the handle on top of the valve. This allows flow through the valve.

Control system scheme

Image Source:

The control system scheme is the most important element in the automation of ball valves. This is due to the fact that it ensures the safe operation of the valve and prevents malfunctions. The control system includes a controller, limit switch, sensor, and actuator. The controller sends signals to the limit switch and sensor.
The limit switch sends a signal to the controller when it detects an error or fault condition. Also, the sensor detects the position of the ball valve stem and sends it as a signal to the controller. The actuator moves according to the instructions given by the controller and opens or closes the ball valve.

Asset compatibility, reliability and criticality

Image Source:

Asset compatibility refers to the size of the pipe that the ball valve will be installed on. This is an important factor because it will determine whether or not your existing equipment can support a particular type of valve. Reliability refers to how rugged the ball valve is against wear and tear over time.
Criticality is another important factor driving the ball valve automation market. Ball valves are used in equipment that requires a high degree of accuracy or where failure could result in serious injury or damage to equipment.

Valve Cost

Image Source:

A ball valve can be made from several different materials, including metal, plastic, and rubber. They are available in many different sizes, materials, and configurations. They are often used in high-pressure applications because they have a larger sealing surface than other types of valves.
The type of material used determines how much force is required to open or close the valve. The price of a ball valve will depend on its size as well as the manufacturer who makes it but the average valves usually cost between $10 and $20.

Types of valve actuators

There are four common types of control valve actuators in process industry applications: electric actuators, pneumatic actuators, manual actuators, and hydraulic actuators. Depending on the type of control valve being used, one or more of these types of actuators may be used to control the valve.

Manual valve actuators

Basic Levers

Image Source:

In the manual valve actuator, a lever is attached to the end of a rod. The rod is connected to a piston that moves back and forth inside the cylinder of a hydraulic pump. The rod is connected by a pivot to the lever, which operates the valve.

Latching-Lockable Lever Handle

Image Source:

Latched manual valve actuators are available in various sizes with manual operation and locking lever handle. The latching feature engages automatically when the lever is released, preventing accidental operation of the valve.

Oval Handles

Image Source:

The manual valve actuators with oval handles are used in many different applications. They are designed to operate manually, so they will not require any external power source. They can be used in a wide range of applications, including domestic and commercial plumbing.

Hand Wheels

Image Source: Directindustry

Hand wheels are the smallest, most lightweight, and least expensive type of manual valve actuator. They are used to rotate valves manually, either by hand or with a handle. A hand wheel is attached to the spindle of a manual valve and allows the operator to open or close the valve by turning the wheel.

Manual Valves with Limit Switches

Image Source:

These limit switches use a mechanical linkage that is activated by an operator turning a handle. The operator turns the handle until it reaches its maximum position, whereupon the linkage opens or closes the valve as required.

Pneumatic valve actuators

Rotary Actuators

Image Source:

Rotary actuators are another type of electric valve actuator. These act as normal valves, but instead of using moving parts, they use rotating motions and electromagnetic fields. This allows them to open and close very quickly, making them ideal for applications where speed is important like robotics and computers.

Double-Acting Valves

Image Source:

Double-acting valves are used to control the flow of gas or liquid into and out of a system. They have two ports: one for gas or liquid to enter, and another for gas or liquid to exit. The valve opens by moving a piston inside the cylinder, which allows the port to be opened or closed.

Spring-Return Valves

Image Source:

Spring-return valves are used to control pressure in a pneumatic system. They can be either normally closed or normally open. A spring-return valve will remain in its current state until it is manually changed by an operator, at which point it will return to its default state.

Solenoid Valves

Image Source:

Solenoid valves are electromechanical components that use an electric current to control fluid flow through a pipe or tube. These valves have a moving part (called the stem) that opens the passageway when current flows through a coil of wire wrapped around the stem’s center.

Electric valve actuators

Rotary valve actuators

Image Source:

The parts of electric valve actuators include a motor, gear box, position sensor and wire harness. The motor turns the gearbox which rotates the stem of the electric valve actuator. The position sensor senses when the stem reaches its desired position and sends a signal to the control system which can then turn off or on the valve.
Rotary valve actuators are also known as rotary vane actuators or rotary solenoid valves. They are found in applications where large flow rates are required such as in industrial processes like fluid dispensing or for controlling large volumes of gasses or liquids such as water supply systems, cooling towers and air conditioning systems.

Linear valve actuators

Image Source:

Linear valve actuators are controlled by an electromechanical system. The controller converts the signal from the control system into a mechanical movement. This is done using a linear motor, which comprises an electric coil and a magnetic rotor. The electric coil attracts the magnetic rotor towards it, causing it to move linearly. The speed at which this happens depends on the power of the motor and its load capacity.
Linear actuators with a push-pull cable connection. This is the most common type of electric valve actuator, which is used to open or close a variety of valves, including butterfly valves, ball valves, globe valves, and gate valves. These types of electric actuators are available with various features and include manual override switches for fail-safe operation.

Hydraulic valve actuators

directional control valves

Image Source:

These use hydraulic pressure to move a piston or rotor inside a cylinder. The piston or rotor may be moved in one direction, or it may be moved back and forth in a linear motion. Hydraulic directional control valves are used for things like moving pistons in engines and controlling the flow of fluids through pipelines.

pressure control valves

Image Source:

Pressure control valves regulate the flow rate at low pressure by controlling the amount of relief pressure in relation to the load pressure. Pressure control valves typically have three ports: one for flow in; one for flow out; and one for relief (blow-down). They are used for applications such as oil refineries, power generation stations, chemical plants and pharmaceutical manufacturing facilities.

flow control valves

Image Source:

Flow control valves regulate flow by controlling the rate at which fluid flows through them under pressure (i.e., throttling valves). Flow control valves typically have four ports: two inlet ports, one outlet port, and an external port (or pilot port) that connects via tubing.

ball valve automation: in summary

When it comes to automation, sometimes you need to make sure that everything will run smoothly. Especially when you are dealing with high pressure piping and a significant amount of water. That is why we recommend using a ball valve as your primary control device.

What Is a Locking Valve

A locking valve is a valve that is designed to lock in a specific position. This type of valve is often used in applications where it is necessary to prevent accidental or unauthorized operation of the valve. Locking valves can be operated manually or automatically, and they are available in different forms, such as lockable level valves and lockable flow control valves.

Lockable Ball Valve

Image Source: 91探花

A locking ball valve is a valve that uses a ball as a closure element. The ball has a hole in it that aligns with the flow when the valve is open and blocks the flow when the valve is closed.

Specifically, locking lever ball valves are used in applications where it is important to prevent the valve from being opened or closed inadvertently. The ball is held in place by a stem that is connected to a handle. Meanwhile, the handle is used to open and close the valve.

Different dimensions are used for these locking ball valves. Below are some examples, but you can check other setups here:

• 1-inch locking ball valve / 1 lockable ball valve
• 2-inch lockable ball valve 2 lockable ball valve

Magnetic Lockable Ball Valve

Image Source: 91探花

A magnetic lockable ball valve is a type of valve that uses a magnetic field to keep the ball in place. This valve is often used in high-pressure applications, such as in the gas and oil industries. The ball in the valve is held in place by a series of magnets, creating a seal resistant to high pressure. This type of valve is often used in pipelines or any applications where there is a need for leak-proof seals.

Brass Lockable Ball Valve

Image Source: 91探花

A brass lockable ball valve is similar to a typical ball valve except that it is made from brass. Brass is an excellent material for plumbing due to its durability and corrosion resistance. This type of valve is designed to be installed in a system where there is a need to control the flow of water and prevent backflow.

Lockable PVC Ball Valve

Image Source:

A PVC ball valve is a common amenity used to control water flow in residential and commercial piping systems. The ball valve is a type of quarter-turn valve that is operated by a handle that is attached to the ball. The ball has a hole in the center that is aligned with the flow of the liquid when the handle is in the open position. Closing the handle will also block the hole. In turn, the flow of liquid stops.

Lockable Ball Valves for Water

Image Source: 91探花

This particular ball valve is ubiquitous in industrial, residential, and commercial plumbing systems. It has a spherical disc that controls the water flow by opening, closing, or partially obstructing the flow path. The ball valve is open when the hole through the sphere aligns with the water flow and closed when it’s perpendicular.

Locking Gas Ball Valve

Image Source: 91探花

Locking gas ball valves are designed to prevent unauthorized operation of natural gas lines. This type of valve is equipped with a locking device that must be released before the handle can be turned to open or close the valve. Locking gas ball valves are typically used in natural gas, resource extractive, and power generation systems.

Lockable Gate Valve

Image Source: 91探花

A lockable gate valve is optimal for blocking the flow of liquids or gases. The valve is operated by a handle that is connected to a gate that opens and closes the valve. The gate is usually made of metal or plastic and is connected to the valve’s body by hinges. A padlock can seal the gate valve with a lock in the open or closed position.

Lockable Hose Valve

Image Source: iStockPhoto

A lockable hose valve is a mechanism for regulating the water flow of a hose or similar medium. It is often used in gardens and other indoor / outdoor areas where there is a need to control the amount of water that is being used. A standard hose bib valve lock is usually located at the rear portion of the hose; it has a handle that turns the valve into your desired position.

Lock-up Control Solenoid Valve

Image Source:

Similar to other valves here, a locking solenoid valve is for regulating liquid and gas flow. It is often used in hydraulic systems but can also be used in pneumatic and other types of systems. The fuel lock-off solenoid valve is actuated by a solenoid. Meanwhile, the solenoid is a wire coil that generates a magnetic field when there’s electricity. It is used to open and close the valve, which allows or prevents the flow of fluid.

Lockable Needle Valve

Image Source:

A locking needle valve is essential for tampering prevention of the pipes. Furthermore, it is often used in applications where a high degree of precision is required, such as in laboratory settings. The valve consists of a needle that is inserted into a chamber, which is then sealed. By turning the needle, the user can control the flow through the valve.

Lockable Butterfly Valve

Image Source: iStockPhoto

This quarter-turn valve is for regulating fluid flow. It comes with a butterfly-shaped disc that is attached to a rod that goes through the center of the valve. The rod is connected to a handle on the outside of the valve. When the handle is turned, the disc either opens or closes, depending on which way the handle is turned. A butterfly valve lock is common in the food and beverage, pharmaceutical, and oil and gas industries.

Locked Open Valve & Lock Close Valve Symbol

Image Source:

In industrial documentation, LO means Locked Open, while LC stands for Locked Closed. These symbols apply to various valves, such as butterflies, balls, globes, gates, and others.

Activating either Locked Open or Locked Closed valves are needed for operation safety. Both of these mechanisms ensure that critical valves are in their designated positions while operating. In most cases, manually running these valves is essential to ensure their structural integrity.

Valve Locking Mechanism

Locking valves is a critical safety measure that prevents unauthorized tampering or operation of the valve. But how do you lock a valve in the first place?

There are many different ways to lock a valve, depending on the type of valve you have. But the safest and most effective method is to follow the instructional manual of the valve itself. Each valve has its own locking mechanism or procedure. Special tools are often needed, as well. Hence, it is integral that you strictly follow the instructions for fool-proof operation.

Common Valve Lock Device Types

The following are some of the locking devices commonly used to lock specific valves. Without these locks, sealing the valves might be difficult or impossible.

Air Valve Lock

Image Source:

Air valve locks are devices that are used to restrict unauthorized access or operation of air valves.

Image Source:

These locking gas ball valves are used in commercial and industrial magnetic lockable ball valves. They can also be used to secure both manual and automatic valves.

Water Valve Lock

Image Source:

A water valve lock is a mechanism installed on water valves, such as lockable pvc ball valves, to prevent unauthorized use. These locks are applicable in industrial and commercial setups. However, they are usable in residential applications.

Image Source:

Lockable ball valves for water are available in a variety of designs. You can customize them to meet your specific requirements.

Gas Valve Lock

Image Source:

A gas valve lock is a locking device that is used to secure a locking gas ball valve in a closed position. It is typically used in residential and commercial applications to deter unwarranted access to the gas line.

Image Source:

For example, you can install this device over the handle of a brass lockable ball valve. This prevents the handle from being turned to the open position.

Hydraulic Lock Valve

Image Source:

Hydraulic lock valves are used to prevent the flow of hydraulic fluid in a system. They are typically used in applications where it is necessary to prevent fluid flow under high pressure, such as in a hydrostatic testing system.

Image Source:

Hydraulic lock valves are often used in industrial applications where there is a need to maintain a constant pressure. They can also be used in high-pressure lockable ball valves for water.

Summary

Locking valves are an important safety measure in many industries and related applications. Being able to lock the valves prevent unwanted tampering or operation, ensuring the structural integrity of the valves and their entire lines.

Actuators for ball valves

Source:

Source:

According to Wikipedia, valve actuator is a crucial component in an industrial environment. The actuator is responsible in opening and closing a valve which plays a key role in the industrial process.

hydraulic valve actuators

Source: Inst Tools

Hydraulic valve actuator utilize fluid in their mechanism. To elaborate, fluid plays a key component in the mechanical process of converting energy. This process enables a force that moves the piston which is responsible in opening and closing a valve.Pneumatic variant requires air pressure while hydraulic requires fluid.

However, the maintenance of the hydraulic supply system is pretty costly. Its quick operation may cause a faster soilage of the machine; thus, routinely check-ups should be done.

electric valve actuators

Source: Inst Tools

An electric valve actuator utilizes electricity in its mechanism. Unlike hydraulic and pneumatic actuators, it can operate without the presence of fluid and air pressure; making it perfect for environments with low temperatures where air and fluid may be rendered unusable.

Since it is powered by electricity, it can produce huge amounts of torque. With that, it comes with constant and configurable operating speeds.

A few cons to look out for are that it is a potential fire hazard due to the present variable, has slower operational speeds compared to other types, and tends to be costlier.

Manual valve actuators

Source: Direct Industry

Hand-operated levers or wheels engage a series of gears to open or close the valve in manual valve actuators. Manual valve actuators are limited to applications where automated or remote valve control is not required, despite their low cost and ease of use.

pneumatic actuators

Source: RS Components

Pneumatic valve actuators convert the energy in compressed air into mechanical motion, allowing for automatic or semi-automatic valve operation. They function by containing the air within a chamber and allowing it to expand, resulting in a pressure difference between the inside and outside of the chamber. The air is energized by the pressure differential. It can then be directed away from the chamber and toward the mechanical component that opens and closes the valve.

pneumatically actuated ball valves: types, symbols, and working principles

Pneumatic valve actuators are frequently found in oil refineries, chemical plants, power plants, water treatment, marine terminals and mining.

When compressed air is available in refineries, chemical plants, and pipeline compressor stations, the features and capabilities of on and off ball valve with pneumatic actuator are usually more advantageous. This is due to its working principle that match well where compressed air is frequent.

Rotary actuators

Source: Rotaru Cylinder

A mechanical device that converts electric, hydraulic, or pneumatic energy into rotary motion is known as a rotary valve actuator. This type of actuator is typically defined in degrees and revolves on a circular path. It can be set to finite or infinite, depending on the needs of the customer.

Double-acting valves

Source: Alibaba

Air is supplied to both sides of the piston in a double-acting actuator. Higher air pressure on either side causes the valve to open and close. A single-acting actuator, on the other hand, receives air on one side and uses one or more springs to return the piston to its original position.

Spring return valves

Source: Schlumberger

Spring-return actuators have only one side of the piston supplied with air or liquid, and the energy to move the mechanisms is provided by a spring on the opposite side. The valve is opened or closed using pneumatic or hydraulic pressure from the air or liquid, and the opposite motion is controlled by a spring.

Solenoid valves

Source: Tameson

The solenoid operates on the “electromagnetism” principle. When current flows inside a coil, a magnetic field can be generated in it; the concentration on the core of the flux of magnetic lines is the result when a metal core is situated in a coil, increasing the coil’s induction when compared to an air core.

Common on and off-ball valves with pneumatic actuator

One of the few misconceptions is that actuators and ball valves come in one. Ball valves pair with actuators, making them separate from one another. Actuators, like pneumatic, open and close ball valves. Furthermore, there are two types of pneumatic actuators and these are:

1. Scotch Yoke (dual)

Source:

• Rack-n-Pinion (dual)

Source:

They both perform the same rotational operation on quarter-turn ball valves, but they do so in a different mechanical manner. Both are available in spring return and double (direct) acting configurations. When power or supply air is lost, spring return pneumatic actuators will return to a “fail-safe position.” That position could be open or closed, depending on what is best for the system. When power or supply air is lost, double-acting pneumatic ball valves simply remain in their current position.

2-air actuated ball valve

Source: 91探花

2-air actuated ball valve or double acting ball valve are your best option thanks to their affordability and durability. Because the absence of mechanical springs in most models eliminates the least durable component in the actuator, double-acting actuators are chosen for their lower cost and superior longevity. A high-quality double-acting actuator can often cycle millions of times before failing.

3-way pneumatic ball valve

Source: 91探花

The 3-way ball valve is intended for use in a system with a constant flow of water. In systems where fluid mixing and diversion are required, the use of 2-way valves will necessitate the use of additional accessories.

Stainless steel pneumatic ball valve

Source: 91探花

Stainless steel pneumatic ball valve endures longer. Because valves are designed to open and close, corrosion can be a major issue. When there is too much corrosion, a Ball Valve may break or become immobile. Stainless Steel Ball Valves will fare much better in harsher water conditions. This will result in a more durable valve.

Electrically actuated ball valve: symbol and working principle

The operating principle of the electric motor generates torque, which is transmitted to the valve stem via a shaft. This causes the ball valve to rotate. A gear system is connected to the electric motor shaft to achieve the required torque. The torque capacity is an important consideration when choosing an actuator. This option is well-suited in work environments where pneumatic and hydraulic are rendered unusable.

How do electrically actuated valve work?

A motor and gear train power electric actuators (also known as motorized or rotary ball valves). These are the most commonly used ball valve automation options. Electric actuators are used when there is no air supply to power pneumatic devices.

pneumatically actuated ball valves vs electrically: how to choose

• Power source

Power sources vary among pneumatic actuators and electric actuators. This is due to the presence of compressed air in the former, and the use of electricity in the latter.

• Speed

In terms of speed, pneumatic actuators tend to be quicker, however, this would mean shorter longevity as speed cause more cycle counts. On the other hand, electric actuators tend to be slower, but this is a benefit in their longevity as slower speeds require fewer cycle counts. Weighing these variables is a crucial component in choosing between the two.

• Duty cycle

As mentioned earlier, duty cycles between these two types vary in their speed. The speed directly affects the duty cycle counts of the actuator.

• Safety features/ standard

Normally, pneumatic actuators tend to be safer as there is no fire-hazard present in their mechanism. However, some situations call for the need for an electric actuator especially when there is a lack or no presence of compressed air at all. So, electric actuators tend to fall short of safety standards.

Other actuated valve types: hydraulic actuator valve

Source: Inst Tools

Fluid pressure is converted into motion by hydraulic actuators. They are used on linear or quarter-turn valves in the same way that pneumatic actuators are. Fluid pressure acting on a piston provides linear thrust for gate or globe valves. A quarter-turn actuator generates torque in order to provide rotary motion to a quarter-turn valve.

Control valve actuation

You may have noticed the focus of this article on how actuators perform with ball valves. To expand on the capabilities of actuators, other valves that pair well are globe valves, check valves, gate valves, and butterfly valves. These variants differ in how each stem is at work. For example, control valves are linear because its stem moves in an upward and downward motion. The globe valve is considered to be linear, as it is under the control valve.

As discussed earlier, the different types of actuators, mainly pneumatic, hydraulic, and electric utilize different variables such as air pressure, electricity, and fluids. All these types can cater to the different types of valves mentioned above.

There are different kinds of ball valves according to the ball valve direction of flow. Some are unidirectional, while some are bidirectional. It is important to know the kind of valve you need for your usage and purchase the valve according to your specifications.

Is there a flow direction for ball valves?

Image Source:

Know you required ball valve flow direction when choosing the right ball valve. A unidirectional valve only allows one direction of flow, while a 2 piece ball valve flow direction is both from inlet to outlet and vice versa.

Ball valve flow direction

Why does ball valve installation direction matter?

In the ball valve installation, knowing the direction of the flow is crucial especially for unidirectional flow since it is best to set-up the handle to point to the direction of the flow when open.

Are ball valves multi directional?

There are ball valves that are multi-directional but not all of them are, it depends on the number of seats and ports.

Unidirectional ball valve

Image Source:Metalsvalve

Unidirectional forged ball valves allow the medium to flow to only one direction. This direction is indicated by an arrow outside the ball valve body and points to where the contents flow to. The ball shutter prevents the medium from flowing when the valve is shut.

Single-seat valves like the C and V port ball valve, as well as, some double-seat ball valves are unidirectional or designed for single flow. The seats are usually on the upstream side of the valve.

Bi directional ball valve

Image Source: Metalsvalve

The bidirectional cryogenic ball valve or the two-way ball valve are ball valves that have identical seats on both sides of the ball. These correspond to the upstream and downstream flow of the medium. This double-seat design creates a tight seal in both directions.

Installation of this type of ball valve is less particular since it can be installed in either direction since neither directions affect its sealing capacity.

Should the ball valve be oriented with the flow of water?

If the ball valve is bidirectional then it may be oriented in either direction, but if it is unidirectional , then the water flow direction in the ball valve arrow must be followed.

How to determine the direction flow for a ball valve

The ball valve flow direction standard is indicated by an arrow outside the ball valve body. Furthermore, the lever of the ball valve usually point to the direction of the flow.

ball valve open close direction: which one to handle face

Ball valves are quarter-turn valves that are easy to maneuver whether it be opening or closing the valve.

When the handle is turned clockwise, it closes the valve, and opens the valve when turned counterclockwise, the easiest valve to open and close.

Ball valve opening direction

Image Source:

The lever or handle of the ball valve usually faces the side when closed. Turn the lever towards the flow of the medium or towards the arrow, this is usually done in a counterclockwise turn.

Ball valve close direction

Ball valves are closed when the its lever or handle faces the side. Turn the lever a half turn clockwise to close the valve and stop the flow of medium.

2 piece ball valve flow direction: Take it for instance

Image Source: 91探花

The Two piece ball valve is a bidirectional or two-way ball valve that allows flow from either direction.

What does arrow on ball valve mean?

The arrow that is written or cast on a valve indicates the ideal direction of flow for the valve.

Can the ball valve be partially opened ?

Technically, it can be partially opened but users are discouraged to do so since the pressure may be distributed incorrectly and can damage the ball valve seats.

Ball valve installation vertical or horizontal?

Essentially, it can be installed in any direction but any installation that is not the recommended usual way of installation may have effects on the way pressure is handled in the ball valve mechanism.

Can the handle of the ball valve be changed?

Yes, the handle can be changed. It can be replaced for a quick fix if it is damaged. You may also opt to swap it with a higher quality material even prior to any damage.

Valve direction of flow

What valves have a flow direction?

There are other valve types that have valve direction of flow similar to the ball valve. Globe valves, especially the large ones, have the flow direction cast or embossed on its body. Check valves are unidirectional and prevent flow of medium back to its origin direction. Gate valves, on the other hand, are bidirectional or two-way flow and can be shut-off in either direction. While butterfly valves, are essentially bidirectional but have a preferred flow direction indicated in its body.

Control valve flow up or down

Flow to open

Flow to open or FTO flow direction is when a medium or fluid passes through the plug causing the plug to open. Control valves with the FTO flow direction are more common than the flow to close or FTC mechanism. The former is only employed in special uses while the FTO is usually used in more general applications.

Flow to close

Flow to close or FTC is the opposite of the FTO in the sense that the fluid opens the plug when it passes it. This flow direction is usually used in low pressure usage and applications and is less popular than the flow to open flow direction. It is also referred to as reverse flow.

Plumbing ball valve flow direction: in summary

Learning the ball valve flow direction is essential to get the most out of your ball valve and to determine which kind of ball valve flow direction you may need for your specific requirement. The ball valve flow direction is also important when installing your ball valve.

Water tank overflow

Image Source:

Overflowing water tanks are a sign of a significant problem. If your tank is overflowing, you need to address it immediately. It can also cause severe damage to your home and even result in flooding. A water tank overflow occurs when the water level in your storage tank reaches the top of the overflow pipe.

Heavy rains and other weather events cause this. The overflow pipe is installed at the top of your water storage tank for this purpose 鈥� to prevent water from overflowing into your home or yard. However, if you don’t have enough space around your storage tank or if it’s not at least two feet off the ground, you may need to install an overflow pipe.

Let鈥檚 first consider the differences between valves and their applications in the excellent pump. A proper understanding of the primary uses of the check valve and foot valve will further answer the question of which valve option is better for the excellent pump. However, the foot valve is most applicable because it has an open end with a shield to trap debris.

Check valve

Image Source: xhval.com

Can I use a check valve instead of a foot valve for the well?

A check allows the flow of gas or fluid only in one direction. The valve’s external shells (bodies) are made of plastic or metal, and it operates automatically without any external control. They are small, simple, less expensive, and part of household items.

Check valves are mounted anywhere in the suitable pumps primarily to prevent the backflow of fluid, but a foot valve is placed at the bottom of the excellent pump. Furthermore, a check valve has two-port valves, but a foot valve has one opened end, and it’s ideal for use in suitable pumps because it keeps the pump primed and prevents water backflow.

Check Valve Uses

Let’s further consider the popular uses/application of a check valve;

To prevent damage to well pumps and other equipment such as centrifugal pumps caused by water backflow. Also, check valves help prevent mixing different media or contamination involving two reservoirs. For instance, in the case of water treatment plants, the check valve prevents the treated water from mixing with the contaminated one. They equally serve as vacuum breakers to allow air into the piping system to avoid interrupting the liquid flow.

Foot valve

Foot valve is which type of valve.

A foot valve is a non-return valve, a one-way valve, or a retention valve that permits fluid flow only in one direction. As the name implies, a ”foot valve,” it’s installed at the end of a pump or pipeline.

What is Foot Valve

A foot valve is a water pump valve having only one thread at the end of it. When the pump is in operation, pressure builds up that sucks up through the pipe. Placing a foot valve in the good pump extracts water from the underground well in one direction.
When the pump stops working, the pressure reduces. This way, the foot valve prevents any water remaining in the pipe from flowing back into the well. This principle makes the foot valve ideal for ponds, pools, and wells.

What is Foot Valve made From (With Foot Valve Diagram)?

Image Source: Google

Foot Valve Uses

The foot valve is valuable and applicable in several instances, which include;

• It is suitable in all kinds of pneumatic systems to prevent the pump column from draining when the pump is shut down.
• To maintain hydraulic pressure.
• Used in ponds, pools, and other scenarios where the pump is needed, such as lake pumps, deep well pumps, water/well pumps, etc.
• Useful in sump pumps which are applicable in industrial settings.
• Designed to keep the pump primed for a unidirectional flow of liquid.

How Does Foot Valve Works

As earlier stated, a foot valve allows for a unidirectional flow of liquids in a pipe without any reversal, which means it can be used to extract water from the well without a backflow. Let’s consider in-depth the foot valve working animation in pumping and water well.

• Firstly, the valve is mounted at the pick-up end of the piping, that is, the end that allows for water extraction.
• When operating the pump, it sucks water through the pipe. While at the same time, the valve opens, and water flows upward because of the pressure coming from the water.
• When the pump stops working, the upward pressure reduces or stops. The law of gravity takes effect, causing the remaining water to run down the pipe and back into the well. However, the foot valve comes into play, preventing the backflow of the water.
• The water in the pipe exerted much pressure on the foot valve. But because the valve is one-way directional, it doesn’t open at the other end. Instead, the pressure tightens the valve and prevents any reversal of water from the pump back into the well.

Why foot valve is used

A high-quality foot valve conserves energy and prevents well pumps from damaging, prolonging their lifespan. But a foot valve is recommended for any system requiring a one-way liquid flow. There are several situations where a foot valve is needed.
It’sIt’s best to use a high-standard foot valve, as it can be challenging to uninstall once mounted. In addition, a PVC foot valve is cost-effective and lightweight, but when high temperature or pressure is involved, metal valve option like stainless steel and bronze is preferred.

Foot valve for well pump: why you cannot just use a check valve

It鈥檚 crucial to note the difference between a check valve and a foot valve and why you can鈥檛 just use a check valve.

• With the multiple threads present on a check valve, it can be placed at the discharge side of the well pump line to discharge water, but a foot valve can only be placed at the bottom/end of the well pump for water intake to prevent backflow. This way, it prevents the pump from burning out and keeps it primed.
• Also, foot valves are useful on deep well applications to prevent loss of prime in the well piping system, but a check valve is mostly on the discharge side of the pump to prevent water from flowing backward.

Why foot valve is good for well pump

You might be questioning why foot valves are necessary for well pumping. Check out the reasons below;

• Foot valves come with a surge block, which exerts pressure on the valve body to remove residues and allow for easy water flow.
• A foot valve has a strainer attached to its inlet port to prevent dirt in the well from entering the valve and sticking to it.
• A foot valve has NPT connections with a filter attached to it, preventing the valve from clogging, preventing the well pump from being damaged.

How to Replace Foot Valve for Well

A faulty foot valve in your well causes the pump to lose its prime between cycles. Check out this guide below to help replace your foot valve;

• Disconnect the pump from the power source.
• Using an adjustable wrench, loosen the bolts at the top of your good seal.
• , detach the union fitting at the wellhead.
• Remove the pipe from the well and place it on a flat surface.
• Unscrew the valve and remove it from the bottom of the well.
• Clean the thread on the valve and apply a coat of thread sealant.
• Using the pipe wrench, tightly screw the foot valve onto the well.

Foot valve: best choice for a good pumping

As we wrap up, we will argue that the foot valve is the best choice for well pumping because of its many advantages. The internal balls allow quick sealing and valve reaction and flexibility to fit into all types of suitable pumps. This and many more benefits mentioned in this article make the foot valve a better option than other valves.

Foot valves are usually made from heavy-duty cast iron, stainless steel, plastics, PVC, and bronze. Since they’re used for water service purposes, these materials have a long-lasting effect even when immersed in water.

Valve Cv

What it is

The valve Cv demonstrates how much fluid or substance can pass through the valve under its extreme open conditions. Formally known as the valve flow coefficient, it is defined as the gallons per minute water volume that goes through the open valve at 1 pound-fore per square inch (PSI). Determining this coefficient is essential when selecting control valves.

Examples of valve Cv explained

To understand this technical concept better, you can refer to the example problem below.
Let鈥檚 say that you are using your industrial valve to control water flow, which has a specific gravity of 1. If its valve Cv is 1.00, this means that:

• It will allow 1 gallon per minute to pass through.
• It is under the pressure of 1 PSI.

Under the same specific gravity and pressure, the valve Cv should be 2.00 if you want it to have a flow rate of 2 gallons per minute. Overall, it shows that the valve Cv allows you to control your pipelines more precisely.

Valve Cv Formula

While you can find valve Cv calculators online, understanding its core formula is a better way to have a good grasp of the concept. The formula above consists of the following:

• Cv = valve flow coefficient
• Q = rate of flow
• SG = specific gravity
• 螖P = pressure drop

Note that you cannot use the valve flow coefficient formula if any of these components are undetermined.

Flashing & Cavitation, Valve Pressure Drop vs Flow Rate: Differences Among These Cv Factors

Viscosity correction factor

The standard valve Cv values on the market have water as the base fluid, but the valves can also be used in processing many other substances with varying viscosities. Fortunately, most manufacturing projects involve fluids whose viscosity differences can be ignored. If you require specific valves related to viscous conditions, you may refer to the correction factors below.

Image Source: Emerson

Rate of flow

The rate of flow is pretty intuitive with its name. Often represented in gallons per minute (GPM), this variable shows the amount of fluid going through the valve鈥檚 opening per set time. You can find it using the fluid volume and how long it takes for it to bypass the valve.

For example, you are processing two gallons of water. It took it 5 seconds to go through the valve. Hence, the rate of flow in GPM is 24.

Pressure drop

The pressure drop in PSI refers to the difference in pressure along a pipe due to the fluid鈥檚 friction against the tube. It is the hardest component to determine since it also considers the length of the pipe, the density of the fluid, diameter, and more. Referring to available charts from resource platforms like The Engineering Toolbox would be more straightforward.

How to Calculate Valve Flow Coefficient

Step 1: Determine the necessary numbers

To be able to use the valve flow coefficient formula, you must first find the numbers that you will substitute for the given variables. Determine the rate of flow, pressure drop, and specific gravity.
Example:

• Rate of flow (Q): 5 GPM
• Pressure drop (螖P): 2 PSI
• Specific gravity: 1

Step 2: Replace the variables in the formula

Recall that the valve flow coefficient formula is Cv = Q * 鈭�(SG / 螖P). Plugging the numbers into the variables, we get: Cv = 5 * 鈭�(1 / 2).

Step 3: Calculate

This step involves basic arithmetic rules like PEMDAS. Below is a basic flow of the equation solution.

While the solution is straightforward with a clear set of rules according to the given formula, the first step of determining the correct numbers you need may pose some difficulty.

Cv Flow

Cv to GPM

While it鈥檚 more common for professionals to determine the valve flow coefficient for their pipes, converting the Cv to GPM may also be important to get the correct flow rate anticipated. Note that to find the GPM, you need these three values: Cv, 螖P, and SG.

Cv to Kv

Another concept related to the valve flow coefficient is the flow factor. The flow coefficient is an Imperial unit, while the flow factor is its equivalent in the metric system. There are two ways to convert between the two:

• From Cv to Kv = 0.865 * Cv
• From Kv to Cv = 1.156 * Kv

Cv to SCFM

Table from Cole-Parmer庐

The standard cubic feet per minute value represents the flow capacity at precise air pressures, making it different from Cv, which applies to all pressures. Although uncommon, converting Cv to SCFM lets you know about more accurate calculations of a valve鈥檚 flow capacity. To get SCFM, simply divide the Cv by a factor that corresponds to specific air pressures in PSI.

Cv Practice Problem

Here鈥檚 another example of determining the correct valve flow coefficient that you need for your project.

Valve labeling

Image Source:

Valve labeling is important for identifying, classifying and finding valves easily. Valve Labels should be easy to read and understand so that anyone can identify the valve type and its purpose. There are many types of valves that are used in industries such as chemical plants, refineries, power plants, oil refineries, and water treatment plants. Choose the right labels for the industrial valves that suit your requirement.

Valve images with names

Valve labels

Image Source:

Valve tags are preprinted with numbers and standard abbreviations to relay critical pipe content, valve identification, or operation information at the point of use. Valve tags include manufacturer information, valve seat, model number, trim, and body material.

Valve size

The valves in your plumbing system are the most important part of your system. They allow water to flow through your pipes and into your home or business. The valve pipe size is frequently specified in inches, but it may also be specified with a DN prefix. The DN number refers to the nominal diameter of the pipe in millimeters (mm).

Valve body

The valve body is an assembly inside the transmission that directs the flow of transmission fluid. It鈥檚 made up of many valves, which open and close to direct fluid to different areas of the transmission. If a valve fails to work properly, it can cause your vehicle to shift hard or not at all.

Pressure class

“PN” stands for pressure nominal. The number following PN indicates the valve’s pressure class in bars, where 1 bar equals 14.5038 PSI. Some manufacturers may also include the pressure rating in PSI. For example, a 4-way valve with PN16 is rated for 16 bar (250 PSI).

How to identify valve marking or labeling (With Examples)

Image Source:

1. The first step in identifying a valve is to determine the type of marking or valve identification standard that is used on the valve. There are three main types of markings found on valves: Markings on the body of the valve. The body of the valve has manufacturer markings, such as “Made in USA.”
2. Stem markings can include dimensions such as stem length and diameter as well as pressure ratings for use with specific media such as steam or water.
3. Most valves have the information printed on them, but if you can’t find it there, check the catalog or specification sheet for the valve you’re looking at.

Valve Rating VS Valve Standard: what’s their differences?

Valve class rating

The valve class rating is a code that indicates the maximum allowable working pressure for a valve. The valve class rating also indicates the type of fluid being handled, as well as the temperature range in which it can be used.

The valve class rating is usually stamped into the body of the valve, either directly onto the body or on a tag attached to it. Valve manufacturers use different methods to indicate the valve class rating. Some stamp it directly onto the body, while others use an external tag that can be removed and replaced with another tag if necessary.

Valve standard

A valve standard is a document that sets out technical specifications for valves used in water distribution systems. It outlines some basic requirements for design, construction, testing and inspection which must be met by all manufacturers. It also outlines some minimum performance criteria which must be met by all accredited products.

By using this document as a benchmark, manufacturers can easily compare their products with those of other manufacturers who comply with similar standards. Valve standards are published by organizations that have adopted standards for valves.

Valve standard: a list for your identification

The type of valve you choose will depend on your needs and the type of environment in which it will be used. The main concern that the valve standards are required is to ensure the safety of the product. It is very important for any company to be able to produce safe products, so they can be sold to the public.

What does WOG rating stands for

WOG is a term that has been used for many years in the plumbing industry. It refers to the type of fluid being used in the system being serviced. The WOG rating specifies the maximum pressure per square inch that a valve can withstand, whereas the WOG indicates whether the valve is suitable for Water, Oil, or Gas.

WOG rating chart

WOG rating chart is a chart that shows the WOG (Water, oil, gas) rating of a tank. The WOG rating is a measure of the resistance of a tank to the passage of water, oil and gas. The higher the WOG rating number, the more resistant the tank is to leaks from these substances. WOG rating number includes:

• 400 wog valve
• 600 wog valve pressure rating
• 1000 wog pressure rating
• 1500 wog pressure rating

WSP/SWP rating

What does WSP rating stands for

The working steam pressure (WSP) of a ball valve indicates the maximum steam pressure that it can withstand at its highest temperature rating. This may also be labeled SWP, which stands for steam working pressure.

WSP rating chart

The WSP rating chart on the valve is a test to determine the performance of the valve. This test is conducted in accordance with the American Society for Testing and Materials (ASTM) B86-99a. The rating chart shows the flow capacity of the valve, which is determined by measuring the quantity of water that passes through the valve in a minute. The lower the flow rate, the better the quality of the valve.

PSI rating

The PSI rating of a tire refers to its ability to withstand internal pressure. This number is shown on the side of every tire and it helps you determine how much weight your car can carry. The higher the PSI, the more weight your tires can support. The opposite is true as well: the lower PSI rating, the less weight your tires can support.

CWP

CWP stands for Combined Water and Pressure. A CWP system is used to provide water and pressure to a building or business. The water supply is provided by a water main that feeds into a meter box. The meter box supplies water to the building or business through a series of pipes and valves.

Ansi Class

Image Source:

The ANSI class of a valve refers to its pressure rating. The ANSI class number is composed of three digits and represents the valve’s pressure rating in PSI. For example, a valve with an ANSI class of 150 means that it can handle up to 150 PSI (10 bar).

Piple classes VS pressure number

The major difference between piple classes and pressure numbers is that piple classes are assigned to valves based on their design characteristics, whereas pressure numbers are assigned based on the pressure rating of the valve.

Ball Valve Rating

Ball valve pressure ratings

The rating of a ball valve is based on its ability to withstand a certain pressure without leaking. This rating is determined by how much force acts on the ball when it is seated against its seat.

Ball valve pressure – temperature ratings

Image Source:

The pressure rating is the maximum pressure that can be safely applied to a valve without causing it to fail (rupture). The temperature rating is the maximum temperature that can be safely applied without causing failure (melting). Pressure ratings are typically expressed as pounds per square inch (psi).

Ball valve design

Ball valves are measured by their diameter and length. The diameter is the size of the circle, while the length is simply how long it is.When it comes to ball valves, the size of the ball is an important factor. This size determines the flow rate, pressure and temperature range for a given valve. It also determines how much force is required to open or close it. There are many ball valve designs that you can choose from, and it is available in one of the leading manufacturers XVHAL indstural valve co .

Conclusion

The valve marking is a quick way to identify the valve type and size. The markings are in a standardized format that can be used across the globe. This is important because the valve markings help us know what size and type of valve we are dealing with. There are many different types of valves and each one has a unique set of markings. Some valves have numbers on them, while others have letters or symbols. The markings will make it easier for us to identify the proper replacement part.

Although both valves are similar in their operations and functions, we’ll further compare them in terms of construction, working principle, cost, application, etc., as we consider the slight differences.

Plug Valve vs. Ball Valve: What Are They

Plug Valve

Image Source:

A plug valve is a control valve with a conical tapered or cylindrical disc that controls fluid movement via one or more passages that run sideways through the plug. It has a 90-degree rotation that closes the valve and blocks fluid flow, making it different from an eccentric plug valve. This quarter-turn valve uses an offset (eccentric) valve to regulate wastewater flow.

Plug valves are small, simple, and majorly used for cutting, distributing, or channeling media flow. Its primary applications are in medium or low-pressure, low-temperature settings, although some specific types of plug valve work in high-temperature settings also.

Ball Valve

Ball valves are a modified version of plug valves featuring a spherical disc and a circular bored passageway. The spherical disc has a hole called a port which aligns with both ends of the valve allowing for the opening and closing of the valve.

The primary function of the ball valve is to cut off, distribute, and alter the flow of direction of the medium. And has characteristic features that make it ideal for water, solvent, acid, etc. The valve is also applicable in working conditions of harsh media like methane, oxygen, hydrogen peroxide, and ethylene.

Plug Valve vs. Ball Valve Construction

Plug Valve Port

Image Source:

Valve ports are openings in the valve body that permit fluid flow in and out of the valve. Several plug valves have a straight full port bore, especially rectangular port valves. The plug valve full port permits the entire flow of fluid straight through the valve’s body.

Ball Valve Full Port

Image Source:

The ball valve’s full port or full bore allows unrestricted medium flow. It means the ball has a straight fluid flow path without any flow reduction as it passes through the valve. This is because the diameter of the hole and the pipeline size are the same, permitting lower friction loss.

Ball Valve Standard Port

Ball valve ports are either in full or standard sizes. A full port ball valve has the same diameter as the pipe, while a standard port ball valve has a smaller diameter than the pipe’s diameter.

The ball valve standard port has smaller bodies overall, corresponding with the narrowing of the internal size of the valve body.

Plug Valve vs. Ball Valve Working Principles

Plug Valve Mechanism

A plug valve’s working principle relies on a plug with a hollow passage in the valve body. The 90-degree rotation creates an alignment between the pipe and the hole, leading to an open state. When rotated to a 90-degree angle from the open position, the valve sits across the pipe leading to a closed state.

Ball Valve Mechanism

A ball valve has a valve body in which a large sphere with a centrally placed hole, having the same diameter as the pipe’s internal diameter is mounted. When the ball rotates at 90 degrees, the valve produces the through conduit or full bore needed for the unrestricted flow of the fluid and scrapers.

Plug Valve vs. Ball Valve Applications

When to Use Plug Valve

In terms of performance, the plug valve has a cutting edge over the ball valve. Some of its advantages over ball valves are;

• The sealing surface of the plug is much more extensive than that of ball valves and offers a better sealing effect, greater torque, and smaller diameter.
• Plug valves are primarily used in low-pressure-low-temperature services, although some high-pressure and high-temperature plug valve designs also exist.
• Plug valves have a high capacity for directional flow control, even in moderate vacuum systems.
• Plug valves are also efficient in handling gas and liquid fuel.

When to Use Ball Valve

Owing to the advancement in technology, the ball valve’s sealing effect is much better today. It can only be replaced with a plug valve when the sealing requirements are stringent but with a smaller diameter. Other applications of ball valves include;

• Better suited for applications that require faster opening and closing speed or during an emergency because of its quarter turn on/off operation.
• The versatile ball valves are popular in various automated applications, such as gas feed lines, crude oil, turbine, LNG, field gas or polymer plants, compressor or separator skids, water tank farms, oil refinery feedstock lines, hydrocarbon processing, etc.
• Stainless steel ball valves are useful for cooling water, petroleum refining, feed water, brewing, and desalination.
• High-pressure ball valves are perfect for underground, subsea, and cryogenic services.

Plug Valve vs. Ball Valve for Gas

Ball valves typically have a longer lifespan than plug valves. The plug valve suffers a higher likelihood of erosion because of the high torque, and more fluids coming into contact with the cylinder causes the plug valve to suffer a higher chance of erosion.

On the other hand, ball valves have more moving parts, less contact with the fluid medium, and require less torque, making them best for gas flow.

Plug Valve vs. Ball Valve Cost

Plug valves cost considerably lower than a ball valves. The “plug” is entirely covered with bushing, protecting the valve body and plug from wear. The valve can be repaired or updated by changing the bushing and top seal to withstand the long-term service requirements of 300掳C. This temperature range gives plug valves a significant cost advantage over ball valves.

Plug Valve vs. Ball Valve Maintenance

Plug Valve Maintenance

Both control valves need constant maintenance to function efficiently. Plug valves are relatively easier to maintain because they have a simple construction and few moving parts. Moreso, you can easily remove and clean the plug and access the rest of the valve body for hassle-free cleaning.

In addition, plug valves offer a lower cost of maintenance because, in the plug valve, the plug is covered with the bushing, which prevents the body and plug from wearing. And replacing the bushing and top seal is enough to update and maintain the valve’s optimum function and long-term service requirement.

Ball Valve Maintenance

Ball valves are tougher to clean because the ball or disc is located deep inside the valve, making it difficult to access. Over time, the body cavity of the ball valve may accumulate particles and debris from the medium, which further adds to its cleaning and maintenance difficulty.

In addition, Sometimes a ball valve doesn’t shut off completely. In most cases, if the valve closes only partially, you’ll have to replace the valve seat or replace it with a new valve that works more steadily.
