Bi-Directional Metal Seated Butterfly Valve

Bi-Directional Metal Seated Butterfly Valve is designed as a tripple eccentric butterfly valve.Normally it's made with SS plus Graphite Seated. It can also be made into SS Plus PTFE Seated. The seal ring has less displacement when closed under a pressure and less wear(basically none) and produces a micro-angular magnitude for compensation when the butterfly disc is closed. The seal ring is to be a hard metal seal if a stainless steel arc-face ring is used, a fluoride plastic seal if a fluoride plastic ball arc-face ring is used, and a rubber seal if a rubber ball arc-face is used.

Bi-Directional Metal Seated Butterfly Valve Features:

1. This butterfly valve is with compact structure, small size, light weight, flexible operation and easy maintenance.

2. This butterfly valve is designed upon the tripple eccentric sealing principle, reliably sealed without leakage and can ensure long duration.

3. This Butterfly valve has large flow area, flow resistance coefficient, heavy flow capacity.

4. It also features with aging-proof, radiation-proof and durable life.

Such Bi-Directional Metal Seated Butterfly Valve is suitable for the pipeline system in water supply and drainage, high buildings, water treatment, environmental protection, food and beverage, medicine, petroleum, chemical industry, power station and main blower of catalyzation and cracking to act as flow blcoking or adjusting.

Bi-Directional Metal Seated Butterfly Valve can be divided into Wafer Type Bi-Directional Metal seated butterfly valve, Flange Type Bi-Directional Metal Seated Butterfly Valve, Butt-Weld End Metal Seated Butterfly Valve, etc.
