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.
