The floating ball valve vs the trunnion mounted ball valve

Ball valves are fundamental components in many industrial applications, and understanding the differences between the types available is crucial for making the right choice. Two popular designs are the floating ball valve and the trunnion mounted ball valve. Each has its unique features and benefits, making them suitable for different applications.

What is a Floating Ball Valve?

The floating ball valve operates with a ball that is free to float and move in accordance with the flow of the fluid. When the valve is closed, the ball is pressed against the seat by the pressure of the fluid, providing a tight seal. This design is particularly effective in applications with lower pressure and less demanding specifications. It offers simplicity and ease of installation, making it a cost-effective solution for many industries.

What is a Trunnion Mounted Ball Valve?

In contrast, a trunnion mounted ball valve features a ball that is anchored by pins on the top and bottom, allowing for more stability under high-pressure conditions. This design is ideal for larger valves and high-pressure systems, as it minimizes the wear on the seat and provides better control over the flow. The trunnion design means that even as pressure changes, the ball remains fixed in place, making it less likely to wear out over time.

Key Differences

One significant difference between the two types is their application suitability. Floating ball valves are typically used in low-pressure, low-temperature situations, while trunnion mounted ball valves are better suited for high-pressure environments. Additionally, floating ball valves tend to be smaller and simpler in design, making them lighter and easier to handle, whereas trunnion mounted valves can be larger and more complex but better equipped to handle extreme conditions.

Conclusion

Choosing the right valve involves considering your specific application requirements. Whether you need the simplicity of a floating ball valve or the resilience of a trunnion mounted ball valve, understanding these options is vital.
