Flange High Performance Butterfly Valve
The KOSEN High Performance Butterfly Valves are designed on the basis of absorbing the advantages of several different structural butterfly valves. The valve plate seal face of this butterfly valve is spherical arc surface body, and the sealing mechanism achieves a real dynamic seal through system pressure, so it has excellent cutting performance and durability. Its small size, light weight, wide manufacturing range, easy maintenance.
