The main seal is a three-dimensional multi-level metal seal, stainless steel and stainless steel, open or closed valve sealing surface friction between the sealing surface of short stroke, long service life, close the valve is closed tightly, reliable sealing performance. The elastic properties of the composite metal seal ring make the valve leak free.
The use of three eccentric structure design, reduce the friction between the sealing surface, the valve in the actual operation of the process has a role in the compensation of the three, making the valve performance is higher, longer life.
The structure of the truss is adopted, and the streamline design of the valve plate is realized, and the casting quality of the valve plate surface is improved, and the flow resistance is reduced. The stainless steel ring mounted on the body, as the cone structure, conducive to fluid circulation, but also improve the casting quality of the inner cavity of the valve body, reduce the flow resistance.
