Stainless Steel Gate Valve: A certain angle is formed between the two sealing faces of the single-disc or double-discs wedge gate valve and perpendicular to the pipeline axis. It is mainly used for switching on or off the medium within pipelines, that is, it is used in a full open or close manner. The gate valve is widely applicable for oil industry, chemical industry, and power station.

The design of the body-bonnet/gaskets varies depending on the class of the valve. Class 150 gate valves consist of a square joint in 2” and an oval one for all other sizes. Depending on the valve service it can be supplied flat-face gasket with graphite of PTFE. Class 300 and 600 valves consist of a circular spiral wound gasket. Class 900 and above gate valves consist of a ring type joint.

In pressure seal designs the sealing is achieved through a gasket that takes advantage of the internal pressure of the line. The material most commonly used is high-purity graphite being located between the body and the body retainer ring.


1. Small flow resistance for fluid;

2. Only a small force is required for opening/closing;

3. No limitation on the flowing direction of the medium;

4. During opening and closing process, the friction between the disc wedge and the seat is small, so the sealing is reliable ensuring tightness and long service life;

5. The valve stem sealing is realized by the collaboration of flexible and woven graphite. ensuring a more reliable tightness;

6. Optional locking device or stem extension;

7. Optional direct mounting to ISO 5211;

8. Full port.
