BV45TRN-78 Trunnion Mounted Ball Valves
Our trunnion mounted ball valves are built for high-pressure, high-demand industrial applications such as oil & gas pipelines, petrochemical plants, and power stations. The trunnion design supports the ball to reduce seat wear and provides reliable shutoff performance even in the toughest conditions. These valves are compliant with API 6D, ASME B16.34, and fire-safe standards.

Why Choose a Trunnion Ball Valve?
Unlike floating ball valves, trunnion-mounted ball valves are ideal for larger sizes and higher pressures. The ball is anchored by trunnions, reducing load on the seats and allowing smoother, lower-torque operation, making them the go-to solution for critical shut-off applications.
