Top-Entry Trunnion-Mounted Ball Valve is in-line repairable and assures bi-directional sealing of the valve with two independent floating seats. The design of the seats minimizes the torque required to operate the valve without losing the sealing power. This power is assured from zero differential pressure to the valve's maximum rated pressure. These quarter-turn valves to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure (DBB) with the ball in the closed position. The DBB feature allows for verifying that the seats are properly sealing.

Features
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 pressures independent of the body cavity pressure which is ideal to verify the sealing of the seats.
Self-relieving seat rings- two seat rings assure bi-directional sealing of the valves.
Soft-seated valves: In valves designed for standard service, a resilient material is inserted into the metal seat holder to provide a soft-seating acting in addition to the metal-to-metal seating between the ball and seat rings.

Optional Features
Emergency sealant injection stem seal and seat face
Metal seated valves
Double piston effect seats
Extended stem and fittings for below ground service
Numerous body, trim, seal area overlay and seal materials available
