600B: Butterfly Valves/Casting Body type
600S: Butterfly Valves/Fabricated Body type
610S: RING-SEAL type Butterfly Valves

600B 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.
