ZM-80EZ4 inclined-axis variable-displacement cartridge-type hydraulic motor, with stepless displacement adjustment within the specified range of Vgmin and Vgmax, high operating pressure, high power density, and excellent low-speed and starting performance. Comprehensive control options meet diverse application requirements. Optional components include a brake release valve, a flushing valve, and a charge valve; the flushing/charge valve prevents overheating in closed-loop circuits and ensures a minimum system charge pressure.

TECHNICAL FEATURE
01. Torque increases with the pressure differential between the high- and low-pressure sides and with displacement.
02. Output speed depends on the pump’s flow rate and the motor’s displacement.
03. Displacement is adjustable at two points, ranging from Vg max to Vg min.
04. The motor’s mounting flange is designed at the center of the housing (space-saving design).
05. Easy installation—simply plug into the gearbox (no need to account for mounting tolerances).
06. Axial tapered piston, swashplate-type, cartridge-style variable motor.
