Triple Offset Lug Butterfly Valve

In a triple-eccentric lug butterfly valve, the sealing surface of the disc quickly detaches from the valve seat during opening, resulting in almost no friction between the disc and the seat throughout the entire opening and closing stroke. Only at the moment of closing does the disc wedge into the seat and achieve a seal. This completely solves the problem of easy wear on the sealing surface of traditional centerline butterfly valves. Triple offset lug butterfly valves are widely used in industrial pipelines in metallurgy, power, petrochemical, water supply and drainage, and municipal construction where the medium temperature is ≤ 425℃, for regulating flow and cutting off fluid. Materials include cast steel, and stainless steel.
