Pneumatic Valve Actuator Working Principle
Mon, Dec 5, 2022
Pneumatic valve actuators are actuators that use air pressure to drive open, close or adjust valves. Pneumatic actuators are sometimes equipped with certain auxiliary devices, commonly used are valve positioners and handwheel mechanisms. The function of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can achieve accurate positioning according to the control signal of the controller.
