Forged Steel API Ball Valve F316 F316L 3 Pieces Side Entry Ball Valve

Trunnion mounted ball valves are based on a system that provide a fixed ball
and floating seat rings, moving along the valve axis.

The side load given by the pressure acting on the ball is absorbed by the
bearings. At low pressure, the sealing on the seats is obtained by the spring
action on the seat rings. The more the pressure increases, the more it pushes
the seats against the ball.

the trunnion mounted valves are available from ½” to 36” – ASME class 150 to
2500 – as well as API 6A 5000 and 15.000 – in several combinations of
materials and execution to cover all possible service application from low
temperature to high pressure
