Best 10 trunnion valve Manufacturers in the world - Blog

Introduction to Trunnion Valves

Trunnion valves are a type of quarter - turn valve commonly used in various industries, especially in the oil and gas, chemical, and power generation sectors. The distinctive feature of a trunnion - mounted ball valve is the presence of trunnions, which are shafts that support the ball at the top and bottom. This design provides additional support to the ball, reducing the operating torque required to open and close the valve, especially in high - pressure applications. Trunnion valves are known for their excellent sealing performance, high durability, and ability to handle large flow rates with minimal pressure drop. They can be used for both on - off and throttling operations and are available in a wide range of sizes, materials, and pressure ratings to meet different industrial requirements.
