Product Description Product DescriptionA trunnion-mounted ball valve is a specialized type of ball valve designed for high-pressure and large-diameter applications. Unlike floating ball valves, the ball in this valve is supported by a trunnion, which anchors it in place. This design reduces the torque required for operation and minimizes stress on the valve seats, making it ideal for demanding environments. Key Features:Trunnion Support:The ball is held in position by a trunnion (a shaft or post at the bottom and sometimes the top), which absorbs the force generated by fluid pressure.Ensures stability and precise alignment even under high pressure.Double-Block-and-Bleed (DBB):Many trunnion-mounted ball valves are designed for DBB functionality, allowing for system isolation and venting of trapped pressure.Seating Mechanism:Spring-loaded or pressure-assisted seats ensure a tight seal against the ball, regardless of pressure fluctuations.The seats are often self-relieving, allowing excess pressure to escape automatically to prevent damage.Material Options:Body materials include carbon steel, stainless steel, and exotic alloys for corrosion and pressure resistance.Seat materials like PTFE, PEEK, or metal are selected based on the application's temperature and pressure requirements.End Connections:Flanged, butt-weld, or socket-weld ends.Available in various standards, such as ANSI, API, or DIN.Operation:Manual (via a gear operator for larger sizes).Automated options include electric, pneumatic, or hydraulic actuators.Pressure Ratings and Sizes:Typically available in high-pressure ratings, up to Class 2500 or equivalent.Commonly used in larger pipeline diameters. Advantages:Low Operating Torque: Reduced friction between the ball and seats makes it easier to operate, even for large valves.Enhanced Sealing: Effective sealing under both high and low pressures, suitable for critical applications.Durability: The trunnion design minimizes wear and tear on seats, extending service life.Pressure Isolation: DBB capability ensures safety and ease of maintenance.Versatility: Suitable for handling a wide range of fluids, including gas, oil, and corrosive substances. Common Applications:Oil and Gas Pipelines: Long-distance pipelines and offshore platforms.Petrochemical Plants: Handling aggressive chemicals and high-pressure systems.Power Generation: High-pressure steam or cooling systems.LNG Terminals: Cryogenic applications require robust and leak-proof valves.Refineries: Isolation and flow control for process units.
