Pneumatic Gate Valve

Pneumatic gate valves mainly consist of gate valves, linear pneumatic actuators, pneumatic triplets, and limit switches. Due to the structural form of gate valves, linear pneumatic actuators that are matched with gate valves are generally double acting or can be equipped with manual devices. The opening and closing of the pneumatic gate valve produced by Shanghai Meiyan Yi Pump Valve is driven by compressed air. When the gate valve is closed, the sealing surface can also be sealed by the medium pressure, that is, the sealing surface of the gate is pressed against the sealing surface of the valve seat on the other side by the medium pressure to ensure the sealing of the valve sealing surface. But most gate valves still use forced sealing, which means that when the valve is closed, external force must be used to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface.
