Expanding Gate Valve

The expanding gate valve provides superior bi-directional mechanical sealing because the two-piece gate valve assembly expands toward the seat area in the open or closed position. The greater the torque, the tighter the seal. The end result is an extremely heat resistant seal that is unaffected by pipeline pressure or vibration.

Expanding Gate Valve

Product Description

An expanding gate valve is a type of industrial valve used to control the flow of fluids within a pipeline. It is designed to provide a tight seal and is often used in applications where a high degree of isolation is required.

 

Features

1. Design and manufacture according to API 6A and NACE MR0175;

2. Full size design, effectively eliminate pressure drop and eddy current, slow down solid particles in the fluid to wash the valve.

3. The valve plate adopts split - body expansion structure.

4. Achieve low torque operation and low wear during the switching process.

5. Metal seal between bonnet and body.

6. A soft seal or metal seal is used between the disc and the seat.

7. The sealing grease can be injected through the valve regularly to enhance the sealing performance of the valve.

8. The connection mode includes flange type, screw type and clamp type.

9. Non - rubber seal effectively protects valve chamber from well mud, sand, rock, etc

10. Simple, safe plate and seat design, no special tools required, easy to replace
