Product Description

product description
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 commonly used model gate valve form a wedge. The wedge angle varies with valve parameters. The driving modes of forged steel gate valve are: manual, pneumatic, electric, gas-liquid linkage. Gate valves are classified by material: cast iron gate valves, ductile iron gate valves, stainless steel gate valves, forged steel gate valves, etc.

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 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.
