The 4WRAB6E25-1X/G12N9DA/MR proportional directional valve is produced by Bosch Rexroth in the 4WRA Proportional Directional Valves series to regulate actuator motion in hydraulic automation systems. The solenoid operates on a 12 V DC supply, draws up to 30 W, and shows a coil resistance of 4.8 Ω at 20 °C for stable current control. Wiring is completed through a terminal box with a 1/2 in NPT entry, and the housing meets IP65 to resist dust and low-pressure water jets. A covered manual override lets technicians shift the spool manually, while the valve uses an E-coded spool to define flow paths. Three switching positions enable forward, reverse, and centered functions without auxiliary hardware.
The unit conforms to nominal size 6 and mounts on an ISO 4401-3 D03 subplate for straightforward replacement in standardized manifolds. Ports A, B, and P accept operating pressures to 350 bar, whereas port T is limited to 210 bar to suit return-line ratings. Maximum flow reaches 30 l/min, and at a 10 bar pressure drop the nominal flow is 25 l/min, supporting precise speed control of cylinders and motors. NBR seals contain mineral hydraulic fluids and minimize leakage, while an overall weight of 2.1 kg allows easy handling during service. These capabilities combine to deliver compact, proportional control where consistent flow and pressure management are required.
