The pneumatic single-acting actuator uses the pressure of the air source to push the internal components, so that he can push the valve, and after disconnecting the air source for him, he can automatically return to the original position. Pneumatic but acting actuators can be divided into pneumatic shift fork type and pneumatic rack type. Relatively speaking, the pneumatic shift fork type is better. Wicken single-acting pneumatic actuators have one spring at each end, which can reduce the probability of failure. The rack-return type is composed of multiple springs. After the failure, it is easy to damage the valve door, affecting production.
