What is a Trunnion Mounted Ball Valve
Trunnion mounted ball valves are a type of quarter-turn valve used to control the flow of media within pipelines. Unlike traditional floating ball valves, which rely on the stem to maintain alignment and seal the valve, trunnion mounted ball valves feature additional mechanical anchoring at the ball’s top and bottom ends (trunnions). This design provides several advantages, making trunnion mounted ball valves suitable for both low and high-pressure applications.

Advantages of Trunnion Mounted Ball Valves
High Pressure Applications:
Trunnion mounted ball valves are particularly advantageous in high-pressure systems. Unlike floating ball valves where the ball only seals against one side, trunnion-mounted balls are anchored and sealed on both sides. This dual-sealing mechanism ensures better reliability under high pressure and reduces the torque required to operate the valve. Consequently, trunnion mounted ball valves are preferred for critical applications where maintaining a tight seal is crucial.
Spring-Loaded Seats:
One of the significant features of trunnion mounted ball valves is their spring-loaded seats. In floating ball valves, the pressure of the fluid forces the ball against the seats to create a seal. However, this method is less effective at lower pressures. Trunnion mounted ball valves, with their spring-loaded seats, can maintain effective sealing even at lower pressures, ensuring versatility across different operational conditions.
Lower Operational Costs:
Trunnion mounted ball valves contribute to lower operational costs due to their design. The trunnions bear the additional pressure load, reducing the operational torque required to open or close the valve. This design feature minimizes wear on the valve components and extends operational lifespan, thereby reducing maintenance and replacement costs over time.
Design Standards and Specifications:
Trunnion mounted ball valves are designed in accordance with industry standards such as API 6D. These standards dictate the valve’s basic design, dimensions, and testing protocols, ensuring reliability and compatibility across various applications. API 6D also specifies the weights of trunnion mounted ball valves based on different bore sizes and body dimensions, providing clarity and consistency in valve selection.
Double Block and Bleed (DBB) Capability:
Some trunnion mounted ball valves are equipped with double block and bleed functionality. This feature allows the valve to block both upstream and downstream flow, providing enhanced isolation for maintenance or safety purposes. DBB valves are commonly used in applications requiring strict fluid isolation to prevent contamination or ensure safety during maintenance operations.
Applications
Trunnion mounted ball valves find extensive use in industries such as oil and gas, petrochemicals, power generation, and water treatment. Their robust design and reliable sealing capabilities make them suitable for a wide range of pressures and temperatures, from low-pressure water systems to high-pressure oil and gas pipelines.
Conclusion
In summary, trunnion mounted ball valves offer superior performance compared to traditional floating ball valves, especially in high-pressure environments where tight sealing and operational efficiency are critical. Their dual-seal mechanism, spring-loaded seats, adherence to industry standards, and capability for double block and bleed make them a preferred choice for applications requiring reliability, durability, and cost-effectiveness in valve operation and maintenance.
