5 Downhole chokethe development of a subsurface gas-lift chokeMaster Flo Valve Inc. designs and manufactures choke valves and specialty control valves for both surface andsubsea applications to the requirements of ISO and API. Our products meet the CE-marking requirements asneeded by our product innovation through extensive research and development demonstrates our commitment toremaining the leader in choke technology. Our test facilities allow us to develop new products that are fullyqualified to applicable industry standards. Some examples include:E-Series Valve DesignHigh-Temperature valves to 850 F5CB Tungsten CarbideSubsea valves to 18000 ftMulti-Stage TrimValves for HPHT serviceMetal-to-Metal SealsMaster Flo also works in partnership with customers to develop new technology to meet special such examples include.

6 Subsea ChokesSubsea developments are constantly pushing the technology frontier, which results in the need to continuouslyimprove on existing products. Reliability is of critical concern for subsea choke systems. Three general typesof choke systems are available:Bolted-Bonnet StyleThe choke internals are held in place by a bolted bonnet, so these chokes are not intended to be servicedsubsea. They are suitable for modular-retrieval systems or applications where maintenance is not an Insert RetrievableThese chokes are intended for water depths that are suitable for diver intervention. They feature a diver-operatedclamp mechanism that holds the choke internals in place.

7 Double-tapered metal bonnet seals are used forreliable Retrievable (HRV)These chokes are qualified for water depths to 18000 feet (5500 meters) and are available for pressures up to15000 PSIG. The choke internals and actuator are contained as a separate retrievable module that can beinstalled or retrieved by a cable-deployed tool with the assistance of a remote-operated vehicle (ROV). Thismodule incorporates an ROV-operated bonnet clamp to fasten the insert to the choke body. Metal-to-metalseals are used at all critical sealing ActuationSubsea valves also require reliable actuators, and the Master Flo Model SL hydraulic stepping actuator hasbeen developed for this purpose.

8 It is compact, lightweight, and durable and has been qualified to water depthsof 18000 feet (5500 meters). It incorporates internal pressure- and volume-compensation and features amodular construction that allows for a variety of orientation and interface and the commitment to developing technology leads to continuous improvement and reduction inlife-cycle costs for CHOKES AND CONTROL VCE CHOKES AND CONTROL VCE CHOKES AND CONTROL VCE CHOKES AND CONTROL VCE CHOKES AND CONTROL VALALALALALVESVESVESVESVESE-Series Valve RangeMaster Flo s standard range of E-Series valves includes choke valves (right-angle bodies) and control valves (inline bodies)
