CCI - Velocity Control Valves

CCI has been the undisputed leader in the design, development and manufacture of velocity control valves for severe service applications since it designed, built and patented the first DRAG® valve in 1967. Since then, CCI has built and shipped tens of thousands of velocity control valves to customers in a wide range of industries worldwide, including fossil and nuclear power generation, oil and gas production and refining and chemical/petrochemical production and processing.

THE DRAG DISK STACK TRIM

The technologically advanced design of the DRAG disk stack trim controls flowing velocities throughout the valve trim by forcing the process fluid to follow a tortuous path of right angle turns. By combining the unique capability to easily vary the number of turns in each disk passage, the number of passages in each disk, and the number of disks in each stack, CCI is unequaled in the industry.

No one meets your most demanding flow characterization and rangeability requirements like we do. Over the past 30 years the combination of CCI technology and our high standards for quality and engineering expertise has demonstrated to users that the DRAG is the only real solution for the demands of severe control service by providing the following key benefits:

• Proven, highly reliable valve performance and longer intervals between maintenance
• Easy maintenance, quick change trim, no screwed or welded seats
• Long trim life
• Elimination of damaging cavitation, noise and pipe vibration
• Customised valve designs to fit your piping constraints
• Fewer valves needed because the DRAG valve can often do the job of multiple, parallel valves
• Reduced leakage costs: Tight shutoff prevents heat loss due to seal and seat leakage
• Reduced system costs: In many applications, block valves, orifices and/or multiple controls can be eliminated

CCI REPLACEMENT PARTS

When it comes to replacement parts from the original manufacturer, our standards are just as high. Everything is made from the right materials, to the right dimensional specs, by qualified machinists, with N-stamp qualification, when needed. Because many CCI DRAG and CCI-Bailey valves are completely custom-designed and built, the original drawings, specifications, and equipment are available to make the right replacement part for your valve. And all our spares meet the original industry standards for which the valves were designed - APL, ANSI or ASME.

CCI DRAWS ON EXPERIENCE

Our experienced field technicians have the tools and access to all information about the valves we have built so that when your conditions demand it, our people can completely rebuild and re-calibrate a control valve before returning it to service. They'll even help sort out your spares inventory. We also have factory-trained specialists that can handle complete rebuild procedures, including full disassembly and cleaning, welding, overlay and modification or fabrication of needed parts, part matching for tight sealing, reassembly, leak testing, painting and return shipment - and this applies to the smallest cage trim valve and the biggest DRAG® severe service valve.

As over 35% of our workforce consists of graduate engineers our resources are utilized not only in Design Engineering and Technical Support, but also in the Sales, Project Management, Quality Assurance, Manufacturing and Customer Service functions. With our modern and efficient manufacturing facilities in Rancho Santa Margarita, California; Winterthur, Switzerland; Osaka, Japan; and Kyunggi-Do, South Korea, we are globally positioned to meet your needs.
