The opening and closing parts of forged steel gate valves are gate plates. The movement direction of the gate is perpendicular to the direction of the fluid, and the forging gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate of the forging gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves are wedge-shaped and wedge angles vary with valve parameters.
