Wafer Type Triple Eccentric Bu

As one of the leading wafer type triple eccentric butterfly valve,Website:http://www.hugo-valve.com, lug type triple ecentric butterfly valve, high temperature wafer butterfly valve, carbon steel lug butterfly valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service. Wafer type triple eccentric butterfly valve? Description 1, wafer/lug type 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 2, the triple eccentric features and it?s theory for wafer/lug type triple eccentric butterfly valve are : ? ? deviated from pipeline center? ? ? deviated from sealing surface center ? ? the tilted taper When the valve is going to be opened, take advantage of disc eccentric features, the disc and seat contact flashily, then break away from the seat rapidly, which reduced the seal pair?s abrasion, friction torque is small, it?s flexible to open. Conical surface can enable the disc to reach sealing by through seat?s inner bore when the valve be open or closed. Conical disc?s turning radius is larger than contact location?s turning radium of seal pair, so the disc will be more tight when the valve be closed tightly more and more to reach self-locking? ?? 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,....
