Trunnion Ball Valve

The CORTEC “DTB” Compact Trunnion Ball Valve provides oilfield customers a well-established design.

This double trunnion design effectively seals at low pressures, with reduced torque and flow turbulence in the through bore.

 

Features and Benefits

  • Compact Trunnion Ball ValveDouble trunnions and spring loaded seats
    • Reduced torque and ease of operation.
    • Holds ball firmly in place and allow only rotational movement.
    • Independent upstream and downstream seats are spring-loaded, ensuring seats are always in contact with the ball.
    • Tight seal at even very low pressures.
  • The throttling ball design minimizes seat damage. Balls that are 2″ and larger can be throttled by rotating the stem/ball in either direction.
  • Extremely robust and reliable configuration.
  • Every valve comes equipped with a stainless steel vent fitting that allows the body cavity to bleed easily.
