Trunnion mounted ball valves are crucial components in industrial pipelines, renowned for their robust design and reliable performance. These valves feature a spherical structure with a bore through its center, which aligns with the flow path when fully activated. A pivot mounted on a single bearings supports this ball element, enabling it to rotate smoothly within the valve chamber. This rotation governs the control of media through the valve.
The trunnion mounting mechanism offers several benefits over other types of ball valves. Primarily, it provides superior sturdiness 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.
