Three-Eccentric Double-Directional Metal Hard-Sealed Butterfly Valve
This Three-Eccentric Double-Directional Metal Hard-Sealed Butterfly Valve is engineered for harsh working environments in petrochemical, energy & power, metallurgy, and mining industries. It addresses critical pain points of traditional butterfly valves—such as easy seal wear, high leakage, and limited application scope—through its innovative “three-eccentric” structure (non-coaxial layout of valve shaft, disc sealing surface, and valve body sealing surface), combined with metal hard sealing and double-directional sealing technologies.
