When selecting cryogenic ball valves for specialized applications such as LNG, LPG, or hydrogen services, understanding the differences between floating and trunnion-mounted designs is crucial. Both types serve essential functions in controlling flow at extremely low temperatures, but their construction and performance characteristics can significantly impact operational reliability and efficiency.
Design and Operation
Floating cryogenic ball valves feature a ball that is not fixed in place; rather, it floats within the valve body, relying on the pressure of the fluid to create a seal against the downstream seat. This design simplifies operation and is typically more compact, making it suitable for lower-pressure applications. Conversely, trunnion-mounted cryogenic ball valves have a fixed ball supported by trunnions, allowing them to handle higher pressures without deforming. This unique construction enables better torque control and less wear on the sealing surfaces.
Application Suitability
The choice between floating and trunnion-mounted cryogenic ball valves often depends on the specific application requirements. Floating valves are ideal for low-pressure scenarios where compactness and ease of maintenance are priorities. On the other hand, trunnion-mounted valves excel in high-pressure environments, providing enhanced stability and durability. Each type must be evaluated based on the conditions it will face in its operability, including temperature fluctuation, pressure variations, and the nature of the fluid being transported.
Performance and Reliability
Performance reliability is crucial in cryogenic applications. Floating valves can sometimes face challenges in maintaining a tight seal under varying pressures, while trunnion-mounted valves offer more consistent sealing capabilities thanks to their design.
