Pneumatic actuators are actuators that use air pressure to drive the opening and closing or regulating 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 are valve positioners and hand wheel mechanisms. The function of the valve positioner is to improve the performance of the actuator by using the feedback principle, so that the actuator can achieve accurate positioning according to the control signal of the controller. The function of the hand wheel mechanism is to use the control valve directly to control the normal operation of the control system when the control system is powered off, gas is shut down, the controller has no output, or the actuator fails.
