The 4WRAE10E30-2X/G24N9K31/F1V proportional directional valve is manufactured by Bosch Rexroth for the 4WRA Proportional Directional Valves series and regulates hydraulic flow and direction in automated systems. Its nominal size of 10 supports mid-range circuit layouts, while the ISO 4401-05-04-0-94 porting pattern lets the unit mount on standard subplates. A 24 VDC coil supply provides compatibility with common machine control voltages, and the valve accepts a 4–20 mA command input for straightforward PLC control. Solenoid current is limited to 2.5 A, and a coil resistance of 2 Ω at 20 °C defines the initial power draw and heating profile. The electromagnetic assembly is specified for a 100 percent duty cycle so continuous modulation is possible. Wiring is completed through a DIN EN 175201-804 K31 connector, and the IP65 enclosure guards the coil and electronics against dust and water jets.
The valve delivers a nominal flow of 30 l/min for steady-state operation and can pass up to 75 l/min at maximum spool opening to accommodate peak demands. Ports P, A, and B tolerate pressures up to 315 bar, whereas port T is restricted to 210 bar to protect return-line components. Approved operating media are HL and HLP mineral oils defined by DIN 51524, and the internal FKM seals withstand these fluids while resisting thermal aging. Coil insulation survives temperatures up to 150 °C, maintaining reliability during prolonged high-load cycles. A total weight of 6.8 kg informs manifold support and handling requirements.
