1 LEDEEN GS Series Pneumatic and Hydraulic Actuators

2 LEDEEN GS Series typical application For on/off or modulating control of any quarter-turn operated valve. Pneumatic Quarter-turn Actuator MODULAR ASSEMBLY Hydraulic Quarter-turn Actuator Consistent engineering design and efficient modular assembly allows increased flexibility to be achieved. Double acting, single cylinder or dual cylinder are combinations readily available to meet specific pipeline application requirements. Pneumatic Cylinder Spring Cartridge Frame Hydraulic Cylinder Symmetric Yoke Canted Yoke 2

3 Standard Features All models available as double acting or spring return Torque outputs to 5,360 in-lb (60 N m) Open and close travel stops provide ± 3 degrees minimum Scotch yoke mechanism generates powerful opening and closing torque outputs Steel fabricated frame provides rugged foundation of modular assemblies Chrome-plated side load bar with guide block for effective elimination of piston rod deflection Bronze bushing interfaces provide low-friction support of sliding and rotating components Pneumatic Spring Return Actuator Aluminum bronze sliding blocks for a low-friction, low-stress pin connection Steel cylinder assembly provides robust pressure containment for all conditions Nickel-plated cylinder ID ensures sealing surface with excellent corrosion resistance Buna piston seal configurations specifically designed for pneumatic and hydraulic applications Hydraulic Spring Return Actuator Composite guide band on piston provides low-friction guidance and support Steel spring cartridge is fully enclosed from environmental conditions Epoxy-coated prestressed springs provide consistent performance with corrosion protection Seal-welded design construction provides maximum personnel safety standard product characteristics type temperature pressure Pneumatic 0 to 5 psig -22 F to 22 F (3 to 2 barg) Hydraulic (-30 C to 00 C) 5 to 3000 psig (0 to 202 barg) 3
