Metal seal ring with a cut-end is set around the disc.
It has several different seal ring constructions suitable to various service applications.
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.
