1 CHOKES API 6A & 16C Extreme Service/Drilling Chokes Robust Reliable Proven The Standard in Non-Standard Valve Production

2 CORTEC Models CX3 and CXE-II Drilling/Extreme Service Chokes CORTEC Model CX3 Hydraulic or Electric Gear Actuated Choke The CORTEC Model CX3 is a worm gear operated drilling choke that can be driven hydraulically or electrically. The gear assembly allows for very fine incremental flow control adjustments. The manual override provides added insurance that the operator will be able to maintain control in the event of a power loss. Manufactured to PSL-3 under API 6A license API 16C monogram available upon request Compliant to NACE MR0175 Pressures to 15,000 MAWP Available in orifice sizes through 3 SS RTJ weld overlay on inlet/outlet grooves as standard Tungsten carbide reversible trim set allows for extended service life of common wear components Optional gantry system provides for field friendly service and maintenance operations Wear resistant nose cone and two tungsten carbide wear sleeves installed in outlet spool for extended wear protection Chokes utilize a block style body allows for the versatility to adapt to a wide variety of end connection types including ANSI, API and Hammer Union options. Digital position indicator Chokes and control systems can be configured to customer specifications upon request. Gate, seat, stem and bonnet removal tools available upon request CX3 Drilling Choke CORTEC Model CXE-II Hydraulic Piston Actuated Choke CORTEC Model CXE-II is a hydraulic double acting piston actuated drilling choke. The piston design allows for rapid flow control adjustments. CXE-II Drilling Choke

3 CORTEC Models CXC2 and CX6 Drilling/Extreme Service Chokes CORTEC Model CXC2 Hydraulic Piston Actuated Choke The CORTEC Model CXC2 is a hydraulic double acting piston operated drilling choke. CORTEC s piston operator design allows for rapid flow control adjustments. The flanged end body design is interchangeable with many common H2 type chokes in the field today. Chokes and control systems can be configured to customer specifications upon request. Manufactured to API 6A PSL-3 Manufactured to NACE MR0175 API 16C monogram available upon request Available in 1-1/2 or 2 orifice size Available up to 15,000 PSI Tungsten carbide reversible trim set allows for extended service life of common wear components Wear resistant nose cone for extended wear protection (integral with bonnet) One tungsten carbide wear sleeve installed in outlet spool for extended wear protection Digital position indicator Gate, seat, stem and bonnet removal tools available upon request CORTEC Model CX6 Hydraulic or Electric Gear Actuated Choke The CORTEC Model CX6 is a worm-gear driven drilling choke that can be hydraulically or electrically actuated. CORTEC s gear assembly allows for fine incremental flow control adjustments. The block style body allows for the versatility to adapt to a wide variety of end connections types including ANSI, API and Threaded Union options. Manual override ability provides end users added insurance that control ability will be maintained in the event of power loss. The large bore 6 orifice provides effective flow control in high flow rate operations such as deep water managed pressure drilling. Chokes and control systems can be configured to customer specifications upon request. Manufactured to API 6A PSL-3 Manufactured to NACE MR0175 API 16C monogram available upon request Available in 6 orifice size Available up to 5,000 PSI SS RTJ weld overlay on inlet/outlet grooves as a standard Optional gantry system provides for field friendly service and maintenance operations Wear resistant nose cone for extended wear protection Tungsten carbide wear sleeves installed in outlet spool for extended wear protection Electric control options available upon request Manual override capability Digital position indicator Gate, seat, stem and bonnet removal tools available upon request CXC2 Drilling Choke CX6 Drilling Choke

4 CORTEC Control Panels and Manifold Systems In addition to the extensive Drilling / Extreme Service Choke line, CORTEC offers comprehensive turnkey solutions for your operational needs with control panels and manifolds tailored to suit individual preferences and project specifications. CORTEC CX3 Drilling Choke with 1-1/2 Orifice and Optional Gantry for fieldfriendly servicing. 3-1/16 15,000 PSI In-Line Dual Choke Manifolds

5 Drilling/Extreme Service Chokes CORTEC Drilling/Extreme Service Chokes are designed to offer the oilfield operator increased service life and cost savings in high-pressure applications where substantial amounts of solids and abrasives are present. Models are designed for extreme conditions like frac flowback, drilling, choke & kill, coil tubing, well control and snubbing. Models Available in this line include: CX3, CXE-II, CXC2 and CX6. In addition to the rugged design of the choke internals, CORTEC recognizes the need for field friendly options to round out a complete operating system. Control Consoles to include the electronic hardware / software to control either hydraulically or electrically actuated chokes for total system responsibility. Gantry Systems are available on most models to allow the operator to slide and rotate the bonnet assembly for quick, relatively easy trim changes or maintenance Manifold / Skid Systems designed, assembled and tested as a complete system with single source responsibility.
