一．Product Introduction
The main advantages of the pneumatic control valve are that the opening and closing speed of the pneumatic control valve is easy to adjust, the structure is simple, and it is easy to maintain. Due to the buffer characteristics of the gas itself during the operation, it is not easy to be damaged due to jamming. It is more reliable than the electric valve in some explosion-proof situations
