When to Use Trunnion Vs Floating Ball Valve？

When it comes to selecting the right type of valve for your application, understanding the differences between trunnion and floating ball valves is crucial. Both types serve unique functions and are suitable for different operational conditions. Industry experts emphasize the importance of making an informed decision based on the specific needs of your project. A trunnion ball valve is designed with support at both the top and bottom of the ball, which provides stability and allows for a more robust construction. According to Mark Johnson, a valve engineer with over 15 years of experience, "Trunnion valves are ideal for high-pressure applications. The design limits the ball's movement, minimizing wear and tear, which extends the valve’s lifespan." This construction makes them suitable for large diameter pipelines where pressure can be significantly high. On the other hand, floating ball valves feature a ball that floats between two seats. This design allows the ball to move freely and creates a tighter seal when the valve is closed. According to Linda Green, a fluid dynamics specialist, "Floating ball valves are better suited for smaller piping systems with lower pressure. Their design accommodates thermal expansion effectively, and they offer better performance in terms of leakage.” This can be especially beneficial in pipeline systems where pressure and temperature fluctuations are common. Another expert, Tom Rodriguez, highlights an important consideration: "The size of your application really dictates your choice. If you're dealing with a high flow rate in larger applications, trunnion mounted valves are often more reliable. Conversely, floating ball valves work well for smaller sizes and are often less expensive to install due to their simpler construction." Industry standards also recommend using trunnion ball valves in critical applications, such as oil and gas services, where safety is paramount. Compliance with industry regulations can further influence the choice you make. For example, valves used in cryogenic applications might require specially designed products, which can be sourced from companies like Xiangyu. They offer a variety of options including Cryogenic Ball Valve solutions. When considering these factors, it is clear that the decision between a trunnion and a floating ball valve is not just about functionality. It also involves understanding the operational requirements, safety standards, and long-term maintenance costs associated with each type.
