Valve combines capacity with control
The Rotary DRAG axial flow valve combines the elevated capacity found in rotary valves with the precise flow control of a high velocity control valve for the gas transmission market.
The Rotary DRAG axial flow valve combines the elevated capacity found in rotary valves with the precise flow control of a high velocity control valve for the gas transmission market Barrett Niehus, CCI Project Manager, stated, "It is truly revolutionary in this industry; taking established technologies and blending them to provide a solution to the age-old problem of control versus capacity"

Choke valves for unmanned North Sea oil platform
After performance tests at all the extreme design conditions, CCI has been awarded a contract to supply five choke valves to the world's first unmanned oil platform
The design capitalises on the capacity of the rotary design and creates a control valve by employing a series of multiple pressure reducing paths within a portion of the ball.
With more than 28 stages of pressure reduction and high flow capacity, the CCI Rotary DRAG results in precise low-end flow and noise control; while high capacity is achieved through the relatively unobstructed rotary valve trim.
The Rotary DRAG is expected to have a significant impact on the system design choices for owners and operators of gas transmission pipelines.
This technology will impact design considerations for interconnect, distribution and blending stations, and will most likely have an effect on applications that have traditionally used two valves in parallel, since now the same applications will only need the Rotary DRAG valve.
This translates into substantial benefits to both builders and operators of these facilities through a reduction in overall operational and maintenance costs.
