The valves operate in low-temperature cryogenic conditions and to 1,000°F. They feature a patented seat made from self-lubricated, full-contact sintered stainless steel that contains TFE or graphite. This provides positive shutoff and eliminates galling when paired with the hard-coated, super-round ball.
