Shanghai Pneumatic Valve Factory Shanghai Pneumatic Valve Pneumatic Valve High Pressure Valve Product Introduction: Pneumatic belt manual gate valve is a low bracket with pneumatic actuator and manual and its protection mechanism gate. Due to the double-layer cylinder structure of the pneumatic gate valve, the lifting force is doubled compared with the single-cylinder pneumatic gate valve. The valve is equipped with a buffer mechanism that can effectively decelerate the valve and reduce the wear of the valve plate car sealing surface and 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/B. Structural length flange connection B/B.
