GATE VALVE

The gate valve's opening and closing parts are the gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is to say, only rely on the medium pressure to press the sealing surface of the gate valve to the valve seat on the other side to ensure the sealing of the sealing surface, which is self sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate shall be forced against the valve seat by external force to ensure the sealing of the sealing surface.
