Trunnion Mounted Ball Valves
Trunnion mounted ball valves are bubble tight during shut-off. This is achieved by restricting the movement of the ball between the spring loaded upstream sealing seats. The ball is held in position by the stem and trunnion shafts. Initial seat load is provided by the seat springs to give low pressure sealing, after which, the system pressure loads the seats onto the ball when the valve is shut.
All Welded Ball Valve
All welded construction ball valves are designed to API 6A & 6D and are supplied in sizes up to 42 in and are of trunnion mounted design. They are suitable for all onshore, topside and subsea applications.
