Product Technical Data Sheet

Product Name: Flanged Trunnion Ball Valve
Model / Size: 6″ – 150LB – RF / A105 Body / Trunnion Type

  1. Général

This product is a split‑body ball valve with flanged ends and a trunnion‑mounted ball design. It features a double‑seat configuration. Suitable for petroleum, natural gas, long‑distance pipelines, storage tanks, and large‑bore piping systems for on‑off service. The trunnion design reduces operating torque and provides reliable sealing for high‑pressure and large‑diameter applications, ensuring long service life.

  1. Caractéristiques
  1. Trunnion Mounted Ball
    The ball is supported by upper and lower stems, allowing the spring‑loaded or pressure‑energized seats to maintain tight contact with the ball surface. This results in low operating torque and suitability for large diameters and high‑pressure applications.
  2. Double Piston Effect & DIB (Optional)
    Seat design can be Single Piston Effect (SPE) or Double Piston Effect (DPE), enabling bidirectional isolation or Double Isolation and Bleed (DIB) functionality.
  3. Blow‑out Proof Stem
    The stem is designed with a blow‑out proof construction to ensure safety.
  4. Anti‑static Design
    An anti‑static device is provided between the ball and the stem to prevent static electricity accumulation.
  5. Emergency Grease Injection
    Grease injection ports are provided at the seat and stem areas for emergency sealing.
  6. Double Block & Bleed (DBB)
    When the valve is closed, the body cavity can be vented via the bleed valve, providing Double Block & Bleed (DBB) capability.
