It will make the valve has a nonstop fixing surface on the circle and make the valve didn’t touch the seat at all when it is completely opens. This plan will make the seat encounter a less grating and accordingly will delay its lifetime. In common application, this twofold balance butterfly valve is restricted to class 150.
The double eccentric butterfly valve`s sealing ring is made of elastomer fit in disc, it available be used in unidirectional sealing application, Commonly used in the water or municipal water application.
