The pneumatic gate valve is equipped with a pneumatic actuator and a manual mechanism. The gate valve actuator adopts a double-layer cylinder structure. Compared with the single-cylinder pneumatic gate valve, the lifting force is doubled. It has a buffer mechanism that can effectively reduce the wear of the valve plate sealing surface and valve body sealing surface caused by the downward impact of the piston when closing the valve, and can also prevent the gate from getting stuck.
