Structure and Application
Two-piece and three-piece trunnion mounted ball valves, also known as side-entry split-body ball valves, divide the valve body into asymmetrical left and right halves along the cross-section perpendicular to the valve passage axis. They are mainly used in pipelines for cutting off, distributing, and changing the flow direction of the medium. Its trunnion structure ensures an accurate ball position. The standard seat adopts a spring structure to push the seat toward the ball, ensuring good low-pressure sealing performance. Both the upstream and downstream seats of the ball valve can seal, which is the so-called bidirectional sealing characteristic. Using the built-in bleed valve, the middle cavity of the valve body can be drained outward. The trunnion adopts an anti-blow-out protection structure and low-friction coefficient bearings. It features excellent performance, high reliability, wide application, and reasonable price.

Electric trunnion mounted ball valves are suitable for industries such as chemical, petroleum, natural gas, metallurgy, and long-distance natural gas pipelines containing hydrogen sulfide media, high impurities, and severe corrosion.
