Trunnion Mounted Ball Valves: Design, Operation, and Principles
Trunnion mounted ball valves are crucial components in industrial pipelines, 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 unrestricted. A axle mounted on two bearings supports this ball element, enabling it to rotate smoothly within the valve body. This rotation governs the control of media through the valve.
The trunnion mounting mechanism offers several strengths over other types of ball valves. Primarily, it provides superior strength due to the direct load transfer from the ball to the trunnion. This design also allows for compact valve dimensions and facilitates smooth operation even under high force.
