Cast Steel Double Flange Eccentric Butterfly Valve

Flange eccentric butterfly valve is designed with three eccentric or double eccentric configuration. It has hermetic capability reliably which ensure disc never touch with sealing seat when it works. This solve the problem of hermetical seat burden unequally, prolong service life and ensure reliable hermetic capability with advantage of high temperature resistant, wearable and anti-corrosive.

Features:

1.Wtih eccentric structure, the body sealing faces are elastic metal rings and multi-layer sealing face to make the disc

2.Sealing : metal to metal or soft sealing.

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

4.Flange standard: ANSI B16.5, JIS B2212, EN1092.1, GB/T 9113.1

5.Face to face according to ANSI B16.10, JIS B2002, EN558.1, GB/T12221
