Product - 900D Control Valve

​​​​​900D Control Valve​​​​​​​​​​​​​

IMI CCI’s DRAG® technology, pioneered in 1961, is the industry’s leading solution for handling demanding service conditions. The 900D is designed to deliver peak process performance with superior control while minimizing losses caused by valve leakage. IMI CCI’s proven DRAG® technology will reduce your equipment and maintenance costs through dramatic reductions in cavitation and vibration – the root cause of damage to trim, adjacent equipment and piping. Supported by the world class technical expertise of The Valve Doctor® program, the 900D is a continuation of IMI CCI’s industry leading critical application solutions that customers have come to depend on.​

Key features

Multi-stage DRAG®
  • Eliminates cavitation, noise and vibration
  • Increases life and reduces maintenance costs
Tight shutoff
  • Reduces leakage
  • Available in Class IV, Class V & VI with soft seat
Top entry design
  • Teflon and graphite seals available
Trim characterisation
  • Linear and equal percentage
  • Custom characterisation available to match specific process requirements
Easy maintenance
  • Quick change trim allows for ease of maintenance, no internal components are screwed or welded into valve body or bonnet​​


Benefits

Control and reliability
The 900D continues IMI CCI’s tradition of customising valve performance to meet the exacting requirements of your application. In addition to linear and equal percentage characterisation, the 900D can be custom characterised for applications that require critical control.

Solves cavitation
  • Maintains the fluid velocity at minimum levels so that local pressures are unlikely to drop below the fluids vapour pressure
  • Should gas bubbles form, DRAG® reduces the energy to a safe level by dividing the flow into many small channels
  • The 900D adheres to ISA guidelines on trim exit velocity
Solves vibration
IMI CCI has extensive experience in helping customers eliminate the damage caused by vibration. Chart 1 shows the dramatic results of applying DRAG® technology and kinetic energy control. Customers typically experience a 90% decrease in peak vibration with the application of DRAG®, and that enables them to:
  • Eliminate valve and piping damage
  • Minimise system trips
  • Minimise downtime and maintenance costs
  • Eliminate additional piping supports
Solves noise
IMI CCI’s philosophy on noise control is to avoid the creation of noise as opposed to trying to muffle it once it’s produced. With the 900D the amount of noise that must be absorbed by the pipe wall or insulation is dramatically reduced, and the noise sensed in the vicinity of the valve is at acceptable levels:
  • DRAG® operates <85 dba
  • Eliminates worker safety concerns
  • Eliminate additional insulation & acoustic barriers
  • Maximize process flow rates
