API 6A External Sleeve Choke Valve

The Enerpal external sleeve choke valve. The external sleeve control choke has a sleeve that throttles the flow on the external diameter of the ported cage.

Main features

  • Large visual indicator provides position in 1/64 in (bean) as standard
  • External grease port lubricates threads and bearings
  • Stem lock maintains set position
  • Bleed plug assembly vents pressure before disassembly
  • Antirotation key translates rotation from the drive bushing into linear movement of the lower stem/flow plug assembly
  • Two-piece stem is threaded and locked, and is removed from wellbore fluids
  • Large annulus area reduces the risk of body and trim erosion caused by high velocities

Product Description

The Enerpal external sleeve control choke has a sleeve that throttles the flow on the external diameter of the ported cage, it different from the H2 adjustable choke valve needle stem and seat. The external sleeve trim is particularly suited for low-capacity/high pressure-drop applications. The external sleeve is designed specifically for severely erosive service where the combination of high pressure drops and high sand concentrations can reduce the life of a choke.

  • Available in various sizes ranging from EPL15 to EPL80 choke models
  • Tungsten carbide-lined external sleeve and solid tungsten carbide cage/seat provide optimum wear resistance in erosive conditions
  • Metal body-to-bonnet gasket for absolute pressure containment
  • Reverse angle external sleeve improves flow dynamics within the trim
  • Self-flushing, pressure-balanced ports reduced stem loads and actuator output requirements
  • Heavy-duty thrust bearings reduce operating torque
  • Pressure-balance seals are a key feature of the pressure-balanced trim arrangement, reducing operating forces and enabling greater ease of adjustment
