Pneumatic actuator is an actuator that uses compressed air to drive the opening and closing or adjust the valve, also known as pneumatic actuator or pneumatic device, but it is generally called pneumatic actuator. 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. The function of the handwheel mechanism is to use it to directly operate the control valve when the control system is out of power or gas outage, the controller has no output or the actuator fails, so as to maintain the normal progress of production.
