Forged Steel Gate Valve

The opening and closing parts of forged steel gate valve are gate valves. The movement direction of the gate valve is perpendicular to the fluid direction. Forged steel gate valves can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate of forged steel gate valve has two sealing faces. The two sealing faces of the most commonly used mode gate valve form wedge and wedge angle, which vary with the valve parameters. The driving modes of forged steel gate valve are: manual, pneumatic, electric, pneumatic. Gate valve is divided into: cast iron gate valve, ductile iron gate valve, stainless steel gate valve, forged steel gate valve, etc.

merits and demerits

1、Advantages of forged steel gate valve

1. The fluid resistance is small.

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

3. The flow direction of media is unlimited.

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

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

2、Disadvantages of forged steel gate valve

1. The overall dimension and opening height are large. Large installation space.

2. In the process of opening and closing, there is relative friction between sealing surfaces, which is easy to cause scratch.

3. Forged steel gate valves generally have two sealing surfaces, which makes it difficult to process, grind and maintain.
