The group s products are primarily used to control, direct and measure the flow of oil and gas as it is moved from individual wellheads through flow lines, gathering lines and transmission systems to refineries, petrochemical plants and industrial centers for Engineered & Process valves division provides a wide range of valves for use in natural gas, LNG, crude oil and refined products transmission lines.

3 The division also provides critical service valves for refinery, chemical and petrochemical processing businesses and for associated storage terminal applications, particularly through the ORBIT and GENERAL Valve lines which are manufactured at the Little Rock facility. This broad offering has significantly strengthened Cameron s ability to serve as a single source for a wide scope of customer requirements. The ORBIT valves block Valve technology provides valves with unmatched durability, safety and long term performance. In Cameron s valves & Measurement group Little Rock factory, production process teams are organized into manufacturing cells, each with responsibility for quality and on time delivery.

4 Using Six Sigma lean methods the result is a finished product of unmatched excellence, built with precision and pride. Little Rock, ARENGINEERED & PROCESS VALVESCT-ORB- Valve -0108/10 SWP-2 MORBIT 5 THE ORBIT VALVESTANDARD FEATURESORBIT valves are without equal when zero leakage and frequent operation are valves are used globally in over 88% of gas processing plants using molecular sieve systems in switching service. ORBIT valves are used in over 85% of LNG facilities. FRICTION FREE OPENING & CLOSING The tilt and turn action eliminates seal abrasion, which is the major cause of seat wear in conventional ball, gate and plug valves .

5 INJECTABLE PACKING For in service maintenance, stem packing material is injected through the packing fitting, giving complete control of fugitive emissions. (Available on all enclosed bonnet models.) SINGLE SEAT DESIGN The single, stationary seat in the ORBIT Valve seals in both directions and avoids the problems of trapped pressure between seals. LONG LIFE ORBIT valves replace troublesome ball valves , gate valves , globe valves and plug valves . The ORBIT design has performance advantages that reduce plant outage and minimize the cost of ownership.

6 OPTIMUM FLOW Full Port or Reduced Port openings give high CV figures. System pumping efficiency is enhanced and erosion problems are minimized. TOP ENTRY DESIGN In-line inspection and repair, after system depressurizing, simplifies maintenance. DUAL STEM GUIDES hardened stem slots and tough guide pins control the lift and turn action of the stem. SELF CLEANINGT ilting the core away from the seat before rotation causes immediate flow around 360 of the core face. Product flow flushes any foreign material away from the seat without localized, high velocity erosive flow.

7 LOW TORQUE OPERATION ORBIT valves turn easily because seal rubbing is eliminated. WEAR RESISTANT HARD FACING ON CORE The core face is a hard, polished material that will endure the most difficult service, without loss of sealing integrity. MECHANICAL CAM CLOSURE The cam angle at the lower end of the stem provides a mechanically energized : Never remove any part from an ORBIT Valve unless specifically instructed to do so in ORBIT literature, or without first consulting an ORBIT Representative. Incorrect procedure could result in personal injury and/or property & PROCESS VALVESCT-ORB- Valve -0108/10 SWP-2 MORBIT 6 THE ORBIT VALVEQUALITY ASSURANCEC ameron s valves & Measurement group Little Rock manufacturing facility has quality programs that are ISO 9001 and Compliances API 6D ISO 9001.

10 The core tilts away from the seat and line flow passes uniformly around the core eliminates the localized high velocity flow that typically creates uneven seat wear in ordinary ball, gate and plug valves . The core then rotates to the full open absence of seal rubbing during both opening and closing means easy, low torque Valve operation and long term reliable Valve leakage cannot be tolerated, the ORBIT operating principle can be relied upon to deliver a positive & PROCESS VALVESCT-ORB- Valve -0108/10 SWP-2 MORBIT 8 THE ORBIT VALVEThe ORBIT Valve top entry design provides convenient access for inline inspection and repairs when required.
