Real-World Performance Advantages
This high-performance model “CC” Control Choke design offers the oilfield operator specific performance advantages over the conventional needle trim options.
- Low Pressure Recovery Characteristics
- Erosion resistant prolonging trim life
- Pressure balanced to reduce torque
- For severe service applications including abrasive service
- ANSI Seat Class IV &V
- Firesafe
Features and Benefits
- Pressure balanced trim offsets high actuation force and allows for high differential pressures.
- Slotted sleeve provides smooth flow-to-lift transition that reduces noise.
- Maintains low-pressure recovery characteristics to offset potential cavitation and flashing.
- Seat and control sleeve sealing surfaces are not directly exposed to the high velocity flow.
- Highly effective shut-off that meets the practical demands of oilfield applications.
- Adapts to a wide range of inlet and outlet connections and dimensions.
- Fitted with a heavy duty severe service metal bonnet seal ring. (excludes Model “CC1”)
- This design offers “real-world” advantages to noise reduction, reduced cavitation in liquid service, reduced icing in gas service, extended service in abrasive environments, and positive shut-off.
