The pneumatic control valve, which is simply developed, is a device that controls the valve by the electric actuator to realize the valve opening and closing. Of course, you can also regard this device as the upper and lower parts. The upper part is the electric actuator, and the lower part is the valve.

Improper motor selection will significantly reduce the service life of the valve, or quickly lead to internal leakage of the valve, which will endanger the re application.
