Hastelloy Butterfly Valve
Both high-performance and triple-offset GMK Hastelloy butterfly valves are available. As a novel kind of butterfly valve, the Hastelloy high-performance butterfly valve takes the best features from existing designs. This butterfly valve has great cutting-off performance and longevity because the sealing surface of the plate is a spherical arc body and the sealing mechanism creates a true dynamic seal via the pressure of the system. It's portable, lightweight, versatile, and simple to manufacture, fix, and maintain. Metal-to-metal seals are used in the construction of Hastelloy triple offset butterfly valves, which allow for reliable sealing at temperatures ranging from cryogenic to superheated.
