What is control valve actuator?
What is control valve actuator?
An actuator is an assembly fitted to the control valve to provide power for moving the move-able parts – plug, ball or vane. The operation of the control valve essentially involves positioning these move-able parts(plug, ball or vane) relative to the stationary seat of the valve.
What are the two types of valve actuator?
A valve actuator is a mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil). There are two main types of actuators, one for each of the two main types of valves that require them. They are rotary and linear.
What is the difference between valve and actuator?
Basically an actuator just moves things, but it’s POWERED by electric, hydraulic, or pneumatic power. A VALVE is intended to REGULATE the flow of hydraulic or pneumatic pressure, but it’s intent is NOT to create motion.
What are the most common types of valve actuators?
Pneumatic and Hydraulic Actuators One of the common types of actuators are pneumatic, that is, air operated. However, organizations need to choose if they want a linear or rotary pneumatic actuator. A pneumatic linear actuator uses a compressor or manual pump that moves a piston throughout the pipe.
How do I choose a valve actuator?
How to Select an Actuator for Valve
- Move the valve closure member (disc, ball, or plug) to the desired position.
- Hold the valve closure member in the desired position.
- Seat the valve closure member with sufficient torque to provide the desired shutoff specification.
- Provide a failure mode in the event of system failure.
Which way should pool returns face?
Most people like to point the jets in a unified direction, clockwise or counterclockwise. On older pools, return jets might have been built on one side or end of the pool with the skimmer opposite the return jets.
How does a Hayward valve actuator work?
. Hayward valve actuator rotates 2-port or 3-port valves automatically. It can be used with the Aqua Logic system to automate pool/spa operations, cleaner operations, water features, or a variety of other uses. The unique cam setting feature ensures a quick and easy installation with the precise control of water flow.
