Pneumatic manual integrated gate valve wholesale pneumatic manual integrated gate valve price Shanghai manual integrated gate valve manufacturer Shanghai pneumatic valve supply Shanghai pneumatic valve factory, Shanghai pneumatic valve, pneumatic valve, high pressure valve Product introduction: Z pneumatic belt manual gate valve is a pneumatic actuator and manual and Low bracket gate valve with its protective mechanism. Due to the double-layer cylinder structure of the pneumatic gate valve, compared with the single-cylinder pneumatic gate valve, the lifting force is doubled. The valve is equipped with a buffer mechanism, which can effectively slow down the valve and 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. It can also prevent the gate from getting stuck. Implementation of standard design based on B standard standard design standard B. Structural length flange connection B. Connection flange size, B.
