The opening and closing parts of the high and medium pressure gate valve are gates. The movement direction of the gates is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters, usually 5, and the large diameter is sometimes 3. Gate of wedge gate valve:
