Stainless Steel Wafer Eccentric Butterfly Valve

Wafer eccentric butterfly valves are our products with the advantages of long lifetime and energy economized. The product is mainly made up of body, disc, seal ring and actuator. It is designed according to triple eccentric or double eccentric principle and new technology, compatible to soft sealing and metal multi-layer sealing.

Category:

Features:

1.Unique structure, portable, flexible operation, convenient.

2.Reliable sealing to get no leakage for air seal.

3.Flow characteristics tend to the best with adjustment in line.

4.Follow the three or double eccentric principle, which extends the usage lifetime with approximate zero friction for seal faces.

5. Designing standard : API 609, JIS B2064, EN593, GB/T12238

6.Connection type : wafer and lug
