Trunion Mounted Ball Valves

The Flowserve 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. Quarter-turn valves is manufactured to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure with the ball in the closed position.
