API & ASME High Pressure External Sleeve Choke Valve, Cage and Plug Type (Angle Choke Valves, Adjustable Choke Valves)


VIGORPETRO's external sleeve control choke comes with a sleeve that throttles the flow on the external diameter of the ported cage. The external sleeve trim is particularly suited for lowcapacity and high pressure-drop conditions. The external sleeve is designed specifically for severely erosive service to improve the life of a choke specifically for conditions of high pressure drops and high sand concentrations.

External Sleeve control choke features

  1. The Cage and Sleeve are completely made by Tungsten Carbide alloy
  2. Large visual indicator is adjustable by increment of 1/64"
  3. Two-piece stem is threaded and locked, and is removed from wellbore fluids.
  4. Control sleeve and seat sealing surfaces are not directly exposed to the high velocity flow
  5. Lower operating torque with Heavy-duty thrust bearings
  6. Pressure-balanced seals reduce operating forces and enabling greater ease of adjustment
