Main Features
The opening and closing part of the ring-stem gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The open-stem gate valve can only be fully opened and closed, and cannot be adjusted or throttled.When the exposed stem gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed to the valve seat on the other side by the medium pressure 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 must be forced against the seat by external force to ensure the sealing performance of the sealing surface.
