KOSO BUTTERFLY VALVES
600B: Butterfly Valves/Casting Body type 600S: Butterfly Valves/Fabricated Body type 610S: RING-SEAL type Butterfly Valves
Metal seal ring with a cut-end is set around the disc.
This construction realizes low seating force and better shut off performance. It also provides more resistance against very high operating temperature. The seat ring's thermal expansion with fluid temperature fluctuation makes the valve best suited to high-temperature fluid service.
