The 4WRAE10W1-60-2X/G24N9K31/F1V proportional directional valve is produced by Bosch Rexroth within the 4WRA Proportional Directional Valves series. It modulates flow to hydraulic actuators in automated equipment requiring variable position control. Nominal size 10 defines its mounting envelope for standard subplates, and the ISO 4401-05-04-0-05 porting pattern aligns the pressure and return galleries for quick installation. Nominal flow is 60 l/min with a 10 bar differential, providing predictable speed under typical loads, while a maximum flow of 75 l/min covers transient peaks. System pressure may reach 315 bar on the service ports, whereas port T is restricted to 210 bar to protect the tank circuit. Spool symbol W1 delivers symmetrical metering characteristics, and FKM seals retain integrity under hot oil and high pressure.
Control is achieved through a 24 V DC coil that shows 2 Ω resistance at 20 °C, establishing normal current draw. A 4–20 mA command interface supplies the proportional signal, and amplifier settings must remain below the 2.5 A maximum coil current to prevent saturation. The winding can operate up to 150 °C, marking the temperature ceiling for continuous duty. Electrical connection is made via an EN 175201-804 plug coded K31, offering keyed coupling and strain relief. The housing is rated IP65 so dust and low-pressure water jets do not compromise service. Approved hydraulic media are mineral oils of classes HL and HLP to DIN 51524, ensuring compatibility with internal clearances and the installed seal set.
