Plug & Cage

This trim also includes a thick metal outer cage to ensure maximum protection against solid impacts from debris in the flow.

The combined result is a versatile, robust, erosion-resistant trim with suitability for a broad range of challenging applications.

• Available in various sizes ranging from CC15 to CC80 choke models.
• Tungsten carbide plug tip in conjunction with solid tungsten carbide cage optimizes wear resistance in erosive conditions.
• Metal body-to-bonnet gasket for absolute pressure containment.
• Fully guided plug reduces side loading and vibration.
• Self-flushing, pressure-balanced ports reduce 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.
• Metal outer cage protects from impact damage.

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.

All control chokes are available in manually operated or actuated models. Custom-designed trim components to suit a wide variety of C_v capacities and flow characteristics also are available.
