Wafer Lug Triple Eccentric Butterfly Valve

As one of the leading wafer/lug triple eccentric butterfly valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service.Triple Offset lug/Wafer Butterfly ValvesDescription1, Triple-Eccentric Control and Shut-off Butterfly Valve,Lug-type Body,High Performance & High Pressure,Metal Seated,Design Acc. To ASME B16.34 and API 609,Optional Fire-Safe Version Acc.to API 607,Double Flanged and Welding Ends are Optional2, 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 resistance3, 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 4, The triple eccentric butterfly valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to resilient seated butterfly valve, the seal of the eccentric disc could be either metal/Graphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple
