Introduction to Trunnion Valve
Trunnion valves are a type of quarter - turn valve used to control the flow of fluids in pipelines. They are widely applied in various industries such as oil and gas, chemical, power generation, and water treatment. The key feature of a trunnion valve is its trunnion - mounted ball design. The trunnion provides additional support to the ball, allowing the valve to handle high - pressure and large - diameter applications more effectively. This support reduces the operating torque required to open and close the valve, making it more efficient and reliable compared to floating ball valves. Trunnion valves can be designed to be either double - block - and - bleed (DBB) or double - isolation - and - bleed (DIB) valves, which are crucial for ensuring safety during maintenance and operation in critical pipelines.
