Product - 100DPC DRAG® Wellhead Production Choke Valve

Today’s gas field environment means higher wellhead pressures with aggressive fluids with entrained sand and other solid particles. A conventional single stage choke valve is not suitable for this kind of severe service. The need to maintain production rates means that frequent choke repair or replacement is no longer acceptable. IMI CCI has responded to this need by developing the world’s first true severe service choke valve. IMI CCI has been solving severe service control valve problems in the oil and gas industry for over 30 years. The IMI CCI severe service choke uses a combination of proven DRAG® velocity control technology and the best grades of tungsten carbide material used in the industry to provide long trim life and precise process control.



Key features

Seals, Gaskets & Stem
Packing materials selected are explosive decompression resistant

Dual Body Seals
For high integrity toxic services

Pressure Balancing Seals
Reduces actuator/handwheel force Provided with dual wiper rings to keep solids out of sealing areas

Bolted Bonnet
Easy maintenance

Solid Tungsten Carbide Plug
Solid tungsten carbide eliminates galling Excellent erosion resistance. Large balance holes will not clog

Solid Tungsten Carbide Disk Stack
Solid tungsten carbide for erosion resistance. Multi-step letdown to control velocity, erosion and noise. Large flow passages, easily handle solids and dirty fluids

Solid Tungsten Carbide Venturi Seat
Solid tungsten carbide venturi seat in high turbulence zones. Venturi seat transition flows smoothly into valve outlet and piping

DRAG® Disk Stack
Up to six stages of velocity control​


  • Solid tungsten carbide plug, seat and disk stack eliminates erosion and galling
    and extends performance life for maximum productivity

  • Large flow passages to easily handle solids means continued reliable performance

  • Multi-step letdown to control velocity, erosion, noise, and vibration for minimum
    down time and safety

  • Increased rangeability due to a longer stroke means superior performance and control

  • Dual scrapers prevent solids from entering sealing areas for reduced maintenance

  • Venturi seat transition assures smooth flow into valve outlet and piping for problems downstream

  • Easy maintenance, quick-change trim means no trim parts are welded or screwed
    into the body

  • One choke body can handle changing wellhead conditions by swapping trim for
    less down time

  • Up to 6 stages of DRAG® velocity control (with total velocity control trim disk stack)

  • All trim seals are PTFE. PTFE is explosive decompression resistant​
