Features

  • In-line repairable, top-entry, floating design.
  • From -20F to +1,200F (higher temperature available).
  • Truly In-line repairable: No need to cut the valve out of service when maintenance is required (unlike end-entry unibody and three-piece designs).
  • Proprietary metal-to-metal, pressure energized, C-Lok bonnet seal with self-alignment seal memory; eliminates a potential leak path and realignment challenges.
  • 360-degree lapping prevents coating transition peaks which eliminates high friction and torque when cycled.
  • Modular trim kit allows for simple, deliberate repair with a factory trim-set.
  • Scalable design for use in larger applications.
  • Quick, quarter-turn operation mitigates damage from high velocities across seating surfaces (unlike slow opening linear valves).
  • Available with weld pups factory-installed; eliminate field welding dissimilar metals in transition areas.
