ASTM A216 Gate Valves For High Temperature High Pressure And Corrosion Resistance
Gate Valve Overview
They have beautiful and advanced structures. The opening and closing parts of the valve are gate plates. The movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate plates have two sealing surfaces, and the wedge angle is 2°52'. The gate plates between the wedge gates can be made into a whole, which is called a rigid gate plate; they can also be made into gate plates that can produce slight deformations to improve their processability and compensate for the deviation of the sealing surface angle during the processing process. This type of gate plate is called an elastic gate plate.
