Valve Motor

Eaton Corp. (Cleveland, OH) released the HP30 high-pressure disc valve motor for mobile off-highway applications requiring up to 30,000 in-lbs of intermittent torque. Options include a hydraulic parking brake offering up to 3,570 Nm of static holding torque. The device includes bearing pack, break, output shaft, and port mounts. Other features include a no-load pressure drop lower than 200 PSI at 25 GPM of flow. A two-piece balance ring provides mechanical and volumetric efficiencies. Continuous pressure is 170 liters per minute (45 GPM) at 310 bar (45,000 PSI); intermittent pressure is 265 LPM (70 GPM) at 345 bar (5,070 PSI). Maximum inlet pressure is 400 bar (6,000 PSI).
