What is Control Valves?

 

 

Control valves are crucial devices in fluid systems. They are used to regulate the flow, pressure, and other properties of fluids like liquids and gases.A control valve typically has a valve body, a trim (including the valve plug and seat), and an actuator. The actuator moves the valve plug to adjust the opening size, changing the resistance to fluid flow.

FAQ

 

Q: Should control valves be on supply or return side?

A: The return side is preferable as it allows the valve and actuator to operate at a reduced temperature which can help protect valve seats and actuator electronics over the installation lifetime.

Q: What is the best way to test control valves?

A: Valves are tested to ensure that they are functioning properly and providing accurate control of the process. The testing process typically includes a combination of visual inspection, pressure testing, and functional testing. During the visual inspection, the valve is examined for signs of damage, wear, or corrosion.

Q: How do you know if your control valve is bad?

A: One of the most obvious indicators of a faulty control valve is leakage. Leakage can occur either internally or externally. Internal leakage is when the valve does not close completely, allowing some fluid or gas to pass through when it should be shut.

Q: How do you clean a control valve?

A: Spray throttle body cleaner onto the idle air control valve and use a clean cloth or soft brush to scrub gently. Focus on areas with visible dirt and carbon buildup to ensure thorough cleaning. If the valve is heavily soiled, submerge it in the cleaner for several minutes.

Q: What are the criteria for selecting a control valve?

A: When selecting a control valve for process plant, there are many things to be considered. These can include the valve flow characteristic, size, valve body and trim materials, noise, potential for damage from cavitation or flashing, actuator type and size, dynamic response to changes in control signal etc.
