LEDEEN HS Series Compact actuators LEDEEN HS Series Compact Actuators Customer-focused solutions ■■ Save valuable space with one of the smallest compact actuators on the market ■■ Get the best power transmission technology with the high-performance helical spline ■■ Set the valve position precisely with independently adjustable travel stops ■■ Experience the convenience of single-source integrity with Cameron automated valves ■■ Keep your equipment in peak performance with Cameron services Hydraulic double-acting actuator. Hydraulic spring-return actuator. Solid engineering and manufacturing excellence ■■ ■■ ■■ The power piston with torque outputs developed to 1,500,000 in.lbf (photo circa 1966). 2 The LEDEEN Valve Automation Center of Excellence located in Italy has an actuation heritage dating back to 1948. Because Cameron designs and manufactures valves, actuators, and control solutions, our customers benefit from a single point of accountability. The LEDEEN* compact actuator incorporates proven technology first developed in 1966 with the power piston, many of which are still in operation today. Features and Benefits Space savings ■■ Save valuable space with the LEDEEN compact actuator ■■ Significantly reduce piping and support structures in new manifold designs Double-acting actuators Spring-return actuators Size comparison—equivalent scotch yoke actuator on 8-in ANSI 2500. Independently adjustable travel stops Experienced Cameron engineers designed an integrated adjustable travel stop subassembly for precise valve positioning (patent pending). ■■ ■■ Independently adjustable open and close travel stops Precise valve setting to fully open for optimized flow and to fully closed for positive shut-off position ■■ External access to travel stop adjustment ■■ Setting retention with an integrated locking mechanism 3 Typical applications The LEDEEN compact hydraulic actuator is a quarter-turn actuator ideal for space-constrained installations, including ■■ floating production, storage, and offloading (FPSO) vessels, platforms, and offloading buoys ■■ drilling diverters, carbon dioxide (CO2), and liquid mainlines ■■ mining operations. Standard features Hydraulic double acting actuator. ■■ Available as double acting or spring return ■■ Torque outputs to 340,000 in.lbf [38,500 N.m] ■■ Open and close travel stops provide ± 3° minimum adjustment ■■ Helical spline torque-generating mechanism ■■ Low-friction spline treatment ■■ Rugged alloy steel frame ■■ Buna piston seals ■■ Fully welded spring cartridge subassembly ■■ Epoxy-coated springs ■■ Local position indicator ■■ Adaptable to any quarter-turn valve topworks Available options ■■ Hand pump or gearbox overrides ■■ Mechanical partial stroke test device (local or remote operation) ■■ Special seals for low-temperature applications to −76 degF [−60 degC] Standard Product Characteristics Actuator Model Temperature Range, degF [degC] HS −22 to 185 [−30 to 85] Hydraulic spring return actuator. 4 Gauge Pressure Range, psi [bar] 145 to 3,000 [10 to 207] Standard Construction Hydraulic Double-Acting Actuator 10 1 9 2 8 7 3 4 6 5 Item 1 2 3 4 5 6 7 8 9 10 Description Top flange Frame Piston Torque hub Bottom flange Bearing Guide band Seal Travel stop Position indicator Material Alloy steel Alloy steel Alloy steel Alloy steel Alloy steel Alloy steel Teflon® PTFE NBR and PTFE Alloy steel Stainless steel 5 Hydraulic Spring-Return Actuator 10 11 12 9 1 2 8 3 7 4 6 5 Item 1 2 3 4 5 6 7 8 9 10 11 12 6 Description Top flange Frame Piston Torque hub Bottom flange Bearing Guide band Seal Travel stop Position indicator Spring cartridge Spring Material Alloy steel Alloy steel Alloy steel Alloy steel Alloy steel Alloy steel Teflon PTFE NBR and PTFE Alloy steel Stainless steel Carbon steel Spring steel Model Number Designation Cameron offers customizable actuators from the frame type to the override options.
