ANSI Trunnion Mounted Ball Valve

ANSI Trunnion-Mounted Ball Valves are quarter-turn valves designed for high-pressure and large-size industrial piping applications. The ball is supported by fixed upper and lower trunnions, reducing operating torque and minimizing the load transferred to the valve seats. This design provides reliable sealing and smooth operation, particularly in high-pressure services. These valves are widely used in oil and gas pipelines, refineries, petrochemical plants, and process facilities, and can be supplied with various body configurations, pressure classes, materials, and sealing arrangements.
