Trunnion Mounted Ball Valve

A Trunnion Mounted Ball Valve is a type of industrial valve that incorporates additional support for the ball, providing enhanced stability and control, especially in high-pressure and large-diameter applications. The term "trunnion mounted" refers to the fixed shafts, known as trunnions, which support the ball at both the top and bottom. This design allows the ball to pivot within the valve body while maintaining precise alignment and reducing operating torque.

The Features of Trunnion Mounted Ball Valves


Trunnion mounted ball valves offer several key features that make them suitable for a wide range of industrial applications. These features include:
 
High Pressure Capability: This type of ball valve is designed to handle high-pressure applications more effectively than floating ball valves, suitable for applications in oil and gas, petrochemical, and other industries where high pressures are common.
 
Reduced Operating Torque: Trunnion mounted ball valves typically require lower operating torque, making them easier to operate, especially in high-pressure conditions.
 
Enhanced Stability: The trunnion design provides additional support to the ball, ensuring stability and reducing the risk of ball wobbling or misalignment during operation.
 
Bi-Directional Sealing: The valve offers reliable bi-directional sealing, making it suitable for applications where flow direction may vary.
 
Fire-Safe Design: Many trunnion mounted ball valves are designed to be fire-safe, ensuring they can maintain a seal even in high-temperature and fire conditions.
 
Trunnion mounted ball valves are chosen for applications where reliable shut-off, high-pressure capability, and stability in large-diameter pipelines are critical. Their robust design and ability to handle demanding conditions make them well-suited for a variety of industries.
