● Sealing at Clapper-to-seat is metal-to-metal.
● Reliable seal for the seat and clapper, and very easy to repair at well site.
● The seal between the valve body and bonnet is a pressure-energized gasket.
● Bore: 4-1/16"~7-1/16"
● Pressure Class: 10,000PSI ~20,000PSI
● Material Class: AA ~ HH
● Temperature Class: L ~ V (-50℉~ 250℉)
● Product Specification Levels: PSL 1~ PSL 3G
● Performance Requirements：PR 1, PR 2
