Bi-directional metal To metal Butterfly Valve
Three eccentric laminate hard seal flange butterfly valve is a long-life, energy-saving butterfly valve. Its structure adopts the three-dimensional core principle design, and the valve seat adopts the laminate stainless steel with graphite structure of hard and soft sealing compatibility, with exquisite processing and advanced technology. This product is composed of valve body, butterfly disc, laminate seal as valve seat, valve stem, transmission mechanism and other main components. It is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage pipeline.
Bi-directional metal To metal Butterfly Valve-Features
There is three eccentric (offset), the first eccentric, the shaft deviated from the centerline of sealing face; The second eccentric, the shaft deviated from the centerline of pipe and valve; The third eccentric the distinctive included angle between oblique taper angle of eccentric seat and centerline of pipe, thus making seat completely disengaged from the sealing ring during the whole process of open and close. This structure not only uses cam effect, but also eliminates the possibility of abrasion and leakage.
