Product Description

Pneumatic gate valve
has reliable performance, convenient operation and maintenance, and has been widely used in petroleum, chemical, maritime and other departments for all kinds of media control

[pneumatic parallel gate valve characteristics]
1, pneumatic gate valve is equipped with pneumatic actuator and manual mechanism
2, gate valve actuator adopts double-layer cylinder structure, which is compared with single-cylinder pneumatic gate valve. The lifting force is doubled
3, to solve the problem that some valve plates of the single cylinder pneumatic gate valve die in the valve body and can not be opened 4, with a buffer mechanism, can effectively reduce the valve plate sealing surface and valve body sealing surface wear caused by the downward impact of the piston when closing the valve, but also to avoid the phenomenon
of gate jam
