Forged Steel Valve Testing




BB Forged Steel Gate Valve.

The opening and closing part of the forged steel gate valve is a gate, and 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 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 used model gate valve form a wedge, and the wedge angle varies with valve parameters. The driving modes of forged steel gate valve are: manual, pneumatic, electric, gas-liquid linkage.


The valve is designed similar to.

TECHNICAL FEATURES

Advantages of forged steel gate valve

1. Small 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 sealing surface is less eroded by the working medium than the stop valve.

5. The body shape is relatively simple, and the casting process is better.


Disadvantages of forged steel gate valve

1. Both the external dimensions and opening height are relatively large. Larger space is required for installation.

2. During the opening and closing process, there is relative friction between the sealing surfaces, which is easy to cause scratches.

3. Forged steel gate valves generally have two sealing surfaces, which add some difficulties to processing, grinding and maintenance.
