Product Description

Product Description

A 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:

  1. 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.
  2. Double-Block-and-Bleed (DBB):

    • Many trunnion-mounted ball valves are designed for DBB functionality, allowing for system isolation and venting of trapped pressure.
  3. 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.
  4. 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.
  5. End Connections:

    • Flanged, butt-weld, or socket-weld ends.
    • Available in various standards, such as ANSI, API, or DIN.
  6. Operation:

    • Manual (via a gear operator for larger sizes).
    • Automated options include electric, pneumatic, or hydraulic actuators.
  7. 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.
