Product overview
Z641H pneumatic gate valve is a low bracket gate valve with pneumatic actuator and manual and protective mechanisms.Due to the double-layer cylinder structure, the lifting force is doubled compared to the single-cylinder pneumatic gate valve. The valve is equipped with a buffer mechanism, which can effectively reduce the wear of the valve plate sealing surface and the valve body sealing surface caused by the downward impact of the piston when closing the valve, and can also avoid the phenomenon of the gate getting stuck.
