Product Description

Triple Offset Flange Butterfly Valve With Metal Seat

User

The butterfly valve absorbs and digests foreign technology, adopts a three-dimensional eccentric multi-layer metal sealing structure, and is suitable for medium temperature ≤550ºC. It is the best device for adjusting flow and cutting off fluid in metallurgy, electric power, petrochemical, and water supply and drainage pipelines.

Advantage

1. The butterfly plate sealing ring is a soft and hard laminated metal sheet, which has the double advantages of hard metal seal and elastic seal, and has excellent sealing performance in both low and high temperature conditions.
2. The butterfly valve absorbs and digests foreign technology, adopts a three-dimensional eccentric multi-layer metal sealing structure, and is suitable for medium temperature ≤550ºC. It is the best device for adjusting flow and cutting off fluid in metallurgy, electric power, petrochemical, and water supply and drainage pipelines.
3. Adopting three - dimensional eccentric structure, the valve seat and the butterfly plate almost no friction, with more close more tight sealing function.
4. The sealing surface of the valve body is made of surfacing stainless steel and cobalt-based hard alloy. The sealing surface is wear-resistant and has long service life.5. Unique structure, flexible operation, labor-saving, convenient, not affected by medium pressure, reliable sealing performance and long service life.
