Manual Soft Seal Gate Valve

Manual soft seal gate valve, industrial valve, soft seal gate valve opening and closing member is the gate, the direction of movement of the gate is perpendicular to the fluid direction, the gate valve can only be fully open and fully closed, can not be adjusted and throttled. The gate has two sealing faces. The two sealing faces of the most commonly used mode gate valves form a wedge shape. The wedge angle varies with the valve parameters. The nominal diameter is DN50 to DN1200, and the operating temperature is ≤200°C.

Product Details

Product Description

Features

1. Elastic seat sealing gate valve, the main sealing member is a one-piece integral slab covered with rubber. It produces a small amount of adaptive elastic deformation under the action of hydraulic force and water pressure, and forms an excellent sealing effect with the precision cast valve seat.

2. Ductile iron casting shell

3. All rubber gates

4. Integral copper nut

5. Gate rail system

6. Stainless steel valve stem

7. Double thrust bearing (dark rod type DN≤300)

8. Stem axial seal (dark rod type)

9. Inverted sealing structure (dark rod type DN≤300)

10. Middle flange connection

11. Double feet double rings

12. Non-toxic anti-corrosion coating

13. Diversified operation
