High Performance Butterfly Valve

High performance butterfly valve is a new type butterfly valve designed on the basis of absorbing the advantages of several butterfly valves with different structures. The valve plate sealing surface of the butterfly valve is spherical arc. The sealing mechanism achieves a real dynamic sealing through the system pressure, so it has excellent cutting performance and durability. It has small size, light weight, wide manufacturing range and easy maintenance.
