Trunnion Mounted Ball Valve: Master 10 Essential Concepts
When dealing with high-pressure piping systems, selecting the right valve is crucial for safety and efficiency. While standard ball valves are common, they face limitations in demanding applications due to the high torque required for operation. This challenge led engineers to develop a specialized solution: the Trunnion Mounted Ball Valve. This design overcomes the difficulties associated with high pressure, offering significant advantages in terms of ease of operation, required actuator size, and overall cost savings. Understanding the mechanics and benefits of the Trunnion Mounted Ball Valve is essential for anyone working with high-pressure fluid control systems.

Major Takeaways
- The Trunnion Mounted Ball Valve is specifically designed for use in high-pressure piping systems.
- Unlike a floating ball valve, the ball in a Trunnion Mounted Ball Valve is held in position by a trunnion support.
- This support prevents fluid pressure from pushing the ball tightly against the seat, resulting in significantly less torque required for operation.
- Spring-loaded or floating seats are used to maintain a tight seal against the ball.
- The reduced torque requirement allows for the use of smaller actuators, which helps save costs.
- The Trunnion Mounted Ball Valve is commonly utilized in high-pressure pipelines, such as those found in oil and gas systems.
Conclusion
The Trunnion Mounted Ball Valve represents a crucial advancement in valve technology, specifically addressing the challenges posed by high-pressure fluid control applications. By providing robust support for the ball, this design significantly reduces operating torque, enables the use of smaller, more cost-effective actuators, and ensures reliable sealing even under demanding conditions. Its prevalence in critical high-pressure systems like oil and gas pipelines underscores the effectiveness and reliability of the Trunnion Mounted Ball Valve design. Understanding its unique features and operational benefits is key for engineers and technicians working in pipeline and process industries.
