Pneumatic Actuated Gate Valve

Pneumatic gate valve is a gate valve with pneumatic actuator and manual and its protection mechanism. With the help of the valve driven by compressed air, when the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed to the other side by the medium pressure. The valve seat on one side ensures the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.

Pneumatic flange gate valve can be equipped with electric or pneumatic echo device to send valve switch status information. Remote control, centralized control and automatic control can be realized. Reliable performance, easy operation and maintenance, etc. It has been widely used in petroleum, chemical, marine and other departments to control various media.

In order to cooperate with users to realize operation automation, besides supplying this series of products, our factory can also provide cylinder blocks including brackets separately to help users to transform existing various manual gate valves. Install the cylinder block produced by our factory on the valve body cover of the manual gate valve to form a double-cylinder pneumatic manual dual-purpose gate valve.

Using 0.4~0.6MPa (gauge pressure) purified compressed air as the working power, push the piston, drive the gate to make displacement perpendicular to the fluid, and realize the purpose of opening and closing the valve.
