pneumatic actuator valve working
A pneumatic actuator is one component of a control valve package. ... When the actuator receives a pneumatic signal from the pilot, the pressure pushes up on the actuator diaphragm. This opens the valve and allows process fluid or gas through the valve orifice (in a pressure-open/fail-close set up).
What is control valve?
control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.
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.
