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

  • Double 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 bled easily.
  • Primary metal-to-metal seal at valve bonnet and end connections.
  • Quarter-turn design.
  • Operated as manual lever, gear operated, or actuated.
