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.
