Forged steel gate valve refers to a valve in which the closing member (gate) moves in the vertical direction of the centerline of the passage. The forged steel gate valve is mainly used for cutting off in the pipeline. Forged steel gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate of the forged steel gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape, and the wedge shape angle varies with the valve parameters. Forged steel gate valve is a widely used valve, and it is generally used for cutting devices with a diameter of DN≤50.
