Trunnion mounted ball valves are crucial components in industrial systems, renowned for their robust design and reliable performance. These valves feature a spherical body with a bore through its center, which aligns with the flow path when fully activated. A axle mounted on two 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 strengths 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 compact valve dimensions and facilitates smooth activation even under high force.
