Pneumatic Valve Series Pneumatic Parallel Gate Valve Application
Pneumatic gate valves are reliable in performance, easy to operate and maintain, and have been widely used in various media control by departments such as petroleum, chemical, and shipping
Characteristics of Pneumatic Parallel Gate Valve
1. Pneumatic gate valves are equipped with pneumatic actuators and manual mechanisms
2. The gate valve actuator adopts a double-layer cylinder structure, which doubles the lifting force compared to single cylinder pneumatic gate valves
3. Solved the problem of some valve plates of single cylinder pneumatic gate valves being wedged inside the valve body and unable to open
4. Equipped with a buffering mechanism, it can effectively reduce the wear of the valve plate sealing surface and valve body sealing surface caused by the downward impact of the piston when closing the valve, and also avoid the phenomenon of the gate plate getting stuck
