Trunnion Ball Valve

ValvesOnly is a trusted source as the best Trunnion Mounted ball valve manufacturers in USA.

A Trunnion ball valve is used to control the flow of fluids, supported by trunnions at both the top and bottom, which help to secure the ball in place and reduce operational torque. Trunnions are these supports that hold the ball in position and lessen the pressure on the valve seats. Even in situations with high pressure, its design aids in ensuring a tight seal and seamless operation. Because of its design, the trunnion ball valve can withstand harsh industrial settings where durability and dependable performance are essential, including in oil and gas pipelines. Trunnion ball valves are superior to their floating ball equivalents in terms of sealing performance. The robust or metal-to-metal sealing alternatives can be used with the design to provide tight shut-off and prevent leakage throughout a wide range of pressures and temperatures. For the oil and gas sector, where even the smallest leak might have catastrophic repercussions, this function is extremely crucial.

Working Mechanism:

As a working principle a spherical ball with a hollow center, rotates inside the valve body. When the valve is open, fluid is able to move freely through the ball’s hole and through the pipeline without obstruction. The ball turns perpendicular to the flow when the valve handle or actuator is rotated, therefore stopping fluid passage and the flow. In order to maintain consistent sealing performance under high pressure, the trunnion-mounted design stabilizes the ball and stops it from moving. When the valve is closed, seals or seats around the ball’s perimeter provide a tight shut-off that stops leaks. They are crucial in industries where accurate and effective fluid management is required because of its exact mechanism, which guarantees dependable fluid regulation and control.
