A trunnion ball valve features a ball supported by fixed trunnions, which stabilizes the ball and reduces operating torque. This design is ideal for high-pressure and high-temperature applications, offering reliable sealing and durability. It is commonly used in industries such as oil and gas, chemical processing, and power generation.

Features

  • Stable Ball Support: Fixed trunnions hold the ball in place, reducing movement and providing stability, especially under high pressures.

  • Reduced Operating Torque: The trunnion design lowers the force needed to operate the valve, making it easier to control.

  • High Pressure and Temperature Tolerance: Suitable for extreme conditions, including high-pressure and high-temperature applications.

  • Enhanced Sealing: Reliable sealing performance is maintained even under demanding operating conditions.

  • Durability: Built to withstand harsh environments and frequent use, offering long-term reliability and reduced maintenance needs.
