The 4WRA10W60-2X/G24K4/V-589 proportional directional valve is produced by Bosch Rexroth as part of the 4WRA Proportional Directional Valves series. It directs hydraulic flow and positions actuators according to an electrical command in automated machinery. The nominal size 10 interface sets the overall envelope for medium-capacity circuits, while subplate mounting lets technicians swap the unit without disturbing hard lines. A porting pattern of ISO 4401-05-04-0-05 matches standard manifold blocks, and four ports link pressure, tank, and two work lines. Three switching positions provide a centered neutral plus two active directions for reversible motion. Actuation is electrical with external electronics, so a separate amplifier delivers the control current that moves the spool proportionally. A 24 V DC coil connects through an EN 175301-803 K4 plug, and the three-pole (2 + PE) layout affords power, signal return, and protective earth in one compact connector.
The valve passes a nominal flow of 60 l/min at its reference pressure drop, giving designers a firm basis for sizing cylinders or motors. Maximum flow capability rises to 75 l/min, offering headroom for transient peaks without over-restricting the circuit; this reserve helps maintain linear metering and avoids unnecessary energy loss. Operating pressure on the supply and work ports can reach 315 bar, whereas the tank port is limited to 210 bar to protect return-line components. ISO 4406 cleanliness class 20/18/15 defines the allowable particle count so the spool remains responsive and avoids jamming. FKM seals handle elevated temperatures and aggressive fluids, supporting long duty cycles with reduced maintenance. The assembled unit weighs 5.96 kg, a consideration for manifold support, transport, and installation planning.
