Trunnion-mounted ball: Features a fixed ball and floating seat rings. Bearings absorb the side load generated
by the pressure acting on the ball.
Independent ball and stem: The ball and stem are independent to minimize the effect of side thrust from
pressure acting on the ball.
Double block and bleed (DBB): Both seats hold their respective pressure independently of the body cavity
pressure, which is ideal to verify that the seats are sealing.
Soft-seated valves: In valves designed for standard service, a resilient material is inserted into the metal seat
holder to provide a soft-seating action in addition to the metal-to-metal seating between the ball and seat rings.
Self-relieving seat rings- two seat rings assure bi-directional sealing of the valves.
Anti-blowout stem maintained because the stem is retained by the stem cover.
Emergency sealant injection stem seals and seat face
Metal seated valves
Double piston effect seats
Extended stem and fittings for below ground service
Numerous types of body, trim, seal area overlay and seal materials available
