API 602 Welded Flange Gate Valve

The opening and closing part of API 602 forged steel gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The forged steel gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The gate of the forged steel gate valve has two sealing surfaces. The two sealing surfaces of the most common mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters. The drive modes of forged steel gate valves are: manual, pneumatic, electric, gas-liquid linkage.

Forged steel gate valve refers to a valve in which the closing member (gate) moves in the vertical direction of the center line of the passage. The forged steel gate valve is mainly used for cutting off in the pipeline. The forged steel gate valve is a widely used valve, and it is generally used for cutting devices with caliber DN≤50.

Advantages of API 602 forged steel flange gate valve

1. Low fluid resistance.

2. The external force required for opening and closing is small.

3. The flow direction of the medium is not restricted.

4. When fully open, the erosion of the sealing surface by the working medium is smaller than that of the globe valve.

5. The shape is relatively simple and the casting process is good.
