Pneumatic Wedge Gate Valve with Manual Operation
Introduction:
Z6S41 pneumatic wedge gate valve with manual is a low bracket rising stem gate valve with pneumatic actuator (double cylinder with buffer mechanism) and manual and protection mechanism. The valve is adopts double cylinder structure, with double lifting force compared with single cylinder pneumatic gate valve. This structure fundamentally solves the problem of open failure which usually happened in single cylinder pneumatic gate valve. Besides,this gate valve has a buffer mechanism is another advantage. It can effectively reduce the attrition between sealing surfaces.
