Double Flange Triple Eccentric Butterfly Valve

As one of the leading double flange triple eccentric butterfly valve,Website:http://www.hugo-valve.com, double flange triple offset butterfly valve, tricentric butterfly valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service. Double flange triple eccentric butterfly valve  Description Double 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              Valve materials of construction Body Materials: WCB + S.S.or alloy , CF8/CF8M+alloy  Seat Materials: S.S., alloy Disc 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 600 Standard : ANSI,DIN,JIS,GOST  End Connection: flange Operate: Manual, worm gear, pneumatic actuated and electric motorized.
