Stainless Steel Metal-Seat Flange Butterfly Valve

As one of the leading stainless steel metal-seat flange butterfly valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service.DescriptionDouble flange triple eccentric butterfly valve adopted three-dimensional eccentric theory design, which idealized the sealing surface’s space motion trail, there is no friction and interference between sealing surface, choose suitable sealing material, all of this guaranteed the triple eccentric butterfly valve’s sealing, corrosion resistance, high temperature resistance and abrasive resistance, the main features of double flange triple eccentric butterfly valve are as bellow :1, small open torque, flexible and convenient.2, three-dimensional eccentric structure, which makes the disc more tight the more valve closed, reliable sealing reached zero leakage.3, high pressure resistance, corrosion resistance, abrasive resistance and long longevity .    4,Triple Eccentric Butterfly Valves,Double Flanged,Features Three-Way Eccentricity and Unique Elliptical Seat,Designed In Accordance With API 609 With Features Of Bi-Directional and Low Torque,Triple Offset High Performance Butterfly Valve Can Be Used Not Only On-Off But Also Regulating The Flow.Valve materials of constructionBody Materials: WCB + S.S.or alloy , CF8/CF8M+alloy Seat Materials: S.S., alloyDisc Materials: WCB/ duplex S.S./CF8/CF8M/CF3M+STELLITE Stem Materials: SS416/420, 17-4PH, SS304, SS316,S.S.316L, duplex S.S.  Applicable standard Size Range: 4~80"(DN100~DN2000）Pressure: PN10, PN16, PN40,PN64, Class 150-class 600Standard : ANSI,DIN,JIS,GOST End Connection: flangeOperate: Manual, worm gear, pneumatic actuated and electric motorized.
