Trunnion mounted valves are a common choice in industrial pipeline systems due to their ability to manage high-pressure applications effectively. Unlike floating ball valves, trunnion mounted valves have their ball supported at the top and bottom by trunnion bearings. This design helps reduce the torque required to operate the valve, which can be beneficial for automated systems or large pipelines.

One of the notable characteristics of trunnion mounted valves is their capacity to maintain sealing integrity under varying pressure conditions. The seats are designed to adapt to the pressure inside the pipeline, which reduces wear and provides a reliable seal over long periods. These valves are typically used in oil and gas pipelines, chemical plants, and power generation facilities, where handling high-pressure fluids safely is essential.

In addition to their pressure-handling capability, trunnion mounted valves are often chosen for their ease of maintenance. The valve’s design allows the ball and seats to be accessed without removing the entire valve from the pipeline, simplifying inspection and replacement procedures. The supporting trunnions also reduce stress on the valve stem, which can extend the service life of the valve.

Another practical aspect of trunnion mounted valves is their suitability for large-diameter pipelines. Because the torque is independent of line pressure, operators can control flow effectively without requiring extremely large actuators. This feature makes the valves adaptable to various industrial settings while maintaining operational efficiency.

Overall, trunnion mounted valves combine durability, reliability, and manageable operation. Their structural design addresses challenges in high-pressure and large-scale pipelines, making them a practical choice for continuous industrial processes. Regular inspection and proper maintenance can further enhance performance and ensure consistent sealing. The combination of low torque operation, robust sealing, and maintenance convenience contributes to the widespread use of trunnion mounted valves across multiple sectors.
