4 Tips to Select a Trunnion Mounted Ball Valve vs Floating Ball Valve

Choosing the right ball valve is crucial for ensuring the efficiency and safety of fluid handling systems. Two common types are the trunnion mounted ball valve and the floating ball valve. Experts in the industry have shared valuable insights on how to make the best decision for your application. Here are four key tips to consider when selecting between these two types of valves.

1. Understand the Design Differences

According to John Smith, a senior engineer at ValveTech Corp, the fundamental difference between these types lies in their design. “A trunnion mounted ball valve has a fixed ball that is supported by trunnions, allowing it to withstand high pressures,” he explains. In contrast, Maria Gonzalez, a mechanical engineer at Flow Solutions, adds, “a floating ball valve relies on the pressure of the fluid itself to seat the ball against the valve body, making it suitable for lower pressure applications.”

2. Assess the Pressure and Temperature Requirements

Pressure and temperature ratings are crucial factors to consider. Dr. Alan Chen, a hydraulics specialist, emphasizes, “Trunnion mounted ball valves are often more suitable for high-pressure systems, while floating ball valves can handle moderate conditions well.” It’s essential to consult the specifications of each type to ensure compliance with your system's requirements.

3. Evaluate Leakage Rates

Leakage is a significant consideration in valve performance. Sanya Patel, an industrial maintenance manager, points out, “Trunnion mounted ball valves generally offer lower leakage rates compared to their floating counterparts, which could be a deciding factor in critical applications.” Additionally, the materials used for seals and the valve design also contribute to overall leakage performance.

4. Consider the Installation and Maintenance

The ease of installation and maintenance can significantly affect operational efficiency. Tom Hargrove, a valve technology analyst, notes, “Floating ball valves are usually lighter and easier to install, while trunnion mounted valves may require more rigorous support structures due to their weight.” Furthermore, maintenance efforts can differ based on valve design, with some requiring specialized training for proper upkeep.

Conclusion

In summary, selecting between a trunnion mounted ball valve and a floating ball valve involves careful consideration of design differences, pressure and temperature ratings, leakage rates, and the ease of installation and maintenance. By consulting industry experts and understanding these key factors, you can make an informed decision that best meets your operational needs.
