High performance zero leakage metal sealing butterfly valve, through the three eccentric unique structure design makes the valve in the opening and closing process, the sealing surface between does not produce interference, no wear, seal more reliable, long service life.
As the cut-off, regulating equipment widely used in water works, power plant, petrochemical, steel, paper, environmental protection, water supply and drainage system.
Product features:
The elastic properties of a composite metal sealing ring allows the valve with zero leakage performance
■ torque sealing valve to ensure the continuous two-way sealing requirements
■ rotate frictionless design is realized by a unique three eccentric principles, it eliminates the friction between the 90 degree switch rotating seat and the sealing ring
■ integral hardfaced seat can satisfy many requirements of working conditions, long service life, convenient repair
■ stem blow-out proof design, safe and reliable
■ valve shaft axis with the whole design (large specifications for axle design), the valve shaft and the valve plate adopts the reliable sealing pin connection
