Three eccentric metal seal butterfly valve structural features interpreted

1 , three eccentric multi-level metal seal butterfly valve butterfly plate stacked rings of hard and soft metal sheets , metal seals and elastomeric seals with the dual advantages of both low and high temperatures, both with excellent sealing performance.

2 , the use of three-dimensional eccentric structure , seat and disc almost no friction parts inside the valve when closed almost no damage ; This structure greatly improves the performance of the valve in use . And has a more closed more tightly sealing function .

3 , the stem , the lower part is equipped with bushings , each bushing wear and friction generated is small , this structure can prevent wear and adhesion, but also improve the service life.

4, the valve sealing surface , the use of alloy steel or stellite alloy,barrier security seals  sealing surface abrasion, erosion , corrosion resistance ; long service life.

5 , unique structure , switching torque is small , flexible operation, labor-saving , convenient, high pressure from the media , low-impact , reliable sealing performance . Can be used for opening and closing and regulating equipment .
