1 CCI 100 DPC DRAG Wellhead Production Choke Valve

2 2 Severe service DRAG choke valve delivers precise wellhead pressure control with superior reliability and life. Improves well production time Enhances control at wellhead Reduces costs associated with maintenance and repair Improves ability to accommodate changes in well operating conditions Enhances the safety and reliability of production facilities DRAG Technology for Severe Service Choke Valves 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. CCI has responded to this need by developing the world s first true severe service choke valve. CCI has been solving severe service control valve problems in the oil and gas industry for over 30 years. The 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. Typical Conventional Valve Problems Solved by DRAG Technology Requirement Conventional Choke Valve Root Cause(s) Figure 1: Exploded view of DRAG choke disks showing flow path Operation at high pressure differentials for extended periods of time. Improved control at wellhead. Improved resistance to erosion due to sand and other particulate matter entrained in fluids. Ability to accommodate significant changes in well operating conditions over time. Safety and reliability for increasingly demanding and challenging environments. Production time significantly reduced due to frequent repair or replacement of trims and/or bodies. Inability to precisely control pressure and/ or flow. Production time significantly reduced due to frequent repair or replacement of trims and/or bodies. Replace existing valve to address new well operating conditions. Operation of facility and health of employees compromised due to rapid erosion to pressure boundary parts, severe mechanical vibration and excessive noise. Inadequate control of fluid velocities resulting in rapid damage to trim components. Poor rangeability inherent to design. Inadequate control of fluid velocities resulting in high erosion rates and rapid damage to control surfaces of trim components. Inadequate control of fluid velocities resulting in high erosion rates and rapid damage to trim components. Poor material selection. Poor rangeability. Inability to significantly modify existing valve. Inadequate control of fluid velocities.

The resistance to flow provided by these turns (or stages) limits the trim exit velocity to a safe level, regardless of the pressure drop. The DRAG choke valve eliminates problems resulting from excessive fluid velocities such as trim and body erosion, noise, vibration and poor process control. The fluid velocities within the trim of CCI choke valves are typically 1/3 to 1/4 that of conventional single stage chokes. Velocity control protects the trim from erosion and increases the trim life many fold.

Proven Materials of Construction for Superior Wear Resistance CCI chokes utilize solid tungsten carbide trim. The plug is solid tungsten carbide, not just carbide tipped. The disk stack provides for multi-stage letdown and is made from solid tungsten carbide, an industry first. The seat ring is provided with a tungsten carbide venturi, allowing for a controlled, erosion resistant expansion into the choke outlet and downstream piping. Proven Engineered Solutions for Maximum Design Flexibility The CCI 100DPC Production Choke Valve is designed to accommodate a variety of trim sizes and throttling elements (i.e. disk stacks and cages) in order to accommodate changes to well operating conditions that will occur over time. Instead of having to purchase an entirely new valve, CCI can simply re-fit the existing valve with an appropriate trim set that will properly address the new operating conditions.

5 Use this checklist to evaluate the benefits of the CCI severe service choke valve. 5 Benefits CCI 100DPC DRAG Choke Valve Competitors 1 Solid tungsten carbide plug, seat and disk stack eliminates erosion and galling and extends performance life for maximum productivity. 2 Large flow passages to easily handle solids means continued reliable performance. 3 Multi-step letdown to control velocity, erosion, noise, and vibration for minimum down time and safety. 4 Increased rangeability due to a longer stroke means superior performance and control. 5 Dual scrapers prevent solids from entering sealing areas for reduced maintenance. 6 Venturi seat transition assures smooth flow into valve outlet and piping for problems downstream. 7 Easy maintenance, quick-change trim means no trim parts are welded or screwed into the body. 8 One choke body can handle changing wellhead conditions by swapping trim for less down time. 9 Up to 6 stages of DRAG velocity control ( with total velocity control trim disk stack.) 10 All trim seals are PTFE. PTFE is explosive decompression resistant.
