Trunnion Mounted Ball Valves: Design, Operation, and Principles
Trunnion mounted ball valves are crucial components in industrial systems, renowned for their robust design and reliable performance. These valves feature a spherical element with a bore through its center, which aligns with the flow path when fully activated. A trunnion mounted on two bearings supports this ball element, enabling it to rotate smoothly within the valve chamber. This rotation governs the passage of media through the valve.
The trunnion mounting mechanism offers several advantages over other types of ball valves. Primarily, it provides superior durability due to the direct load transfer from the ball to the trunnion. This design also allows for reduced valve dimensions and facilitates smooth movement even under high force.
