[0002] Pneumatic actuators are actuators that use air pressure to open, close or adjust valves. They are also called pneumatic actuators or pneumatic devices, but they are generally called pneumatic heads. Pneumatic actuators are sometimes equipped with certain auxiliary devices. Commonly used ones 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.
