Choke Valve
Choke Valve – External Sleeve
Choke External Sleeve
Control Valve
The external sleeve control choke has a sleeve that throttles the flow on the external diameter of the ported cage. 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.
Features
- Available in various sizes ranging from CC15 to CC80 choke models.
- Heavy-duty thrust bearings reduce operating torque.
- Reverse angle external sleeve improves flow dynamics within the trim.

Plug And Cage Choke Valve
Plug And Cage Control
Choke Valve
The plug and cage control choke uses the plug as the controlling element and throttles the flow on the internal diameter of the ported cage. The ports in the cage are sized and arranged to give the most appropriate combination of control and flow capacity for each application.
Features
- 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
