BS5351 Carbon Steel Turnnion Soft Seated Ball Valve

Soft Seated Industrial Turnnion Mounted Ball Valves

Trunnion mounted ball valves are quarter-turn valves used to stop the flow of medium in pipelines. These valves feature a round or spherical disk in the center that rotates to start or stop the flow. This disk is called a ball and it features a hollow center. Ball valves are extremely versatile and are commonly used in industrial applications where tight shut-off is required.

Trunnion mounted ball valves feature additional support for the ball. This support is in the shape of a shaft and is called a trunnion. The trunnion absorbs any added pressure from the flow, reducing stress on the ball and seats of the valve. Trunnion mounted ball valves are used in high-pressure, large scale applications where low operating torque is required.
