The 4WRPEH10C4B100L-2X/G24K0/F1M proportional solenoid valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series. It meters hydraulic oil in automation circuits, adjusting flow according to an electrical setpoint. The unit is built in nominal size NG10 (ISO 4401-05-04-0-05) so it mounts on standard subplates for mid-range power manifolds. A rated flow of 100 l/min supports actuators that demand moderate volume without exceeding cavity limits. The P, A, and B ports withstand 315 bar while the T port is limited to 250 bar, allowing high-pressure work lines and a lower tank return rating. The valve accepts a 24 V DC supply and interprets a 4–20 mA command to position the spool, enabling closed-loop control from common PLC analog outputs. Electrical loading reaches 60 VA, and continuous operation is permitted thanks to a 100 % duty cycle. These electrical figures ensure stable performance when the valve is held energized for long periods.
The wiring interface is a 6-pole plus protective earth connector compliant with DIN 43563, providing quick exchange during service. An IP65 enclosure rating shields the electronics from dust and low-pressure water jets, making the valve suitable for machine frames with incidental fluid spray. The hydraulic path requires fluid cleanliness no worse than ISO 4406 class 18/16/13 to prevent spool wear and maintain accuracy. Viscosity may be as high as 800 mm²/s, which allows the device to handle cold-start or heavy-oil conditions without sticking. NBR seals are fitted to resist standard mineral oils used in industrial power units. The control cabinet should include a 2.5 A fast-acting fuse to protect the coil, and a 200 Ω shunt resistor may be inserted for current feedback or fault monitoring circuits. Total mass is 7.1 kg, so standard manifold supports are sufficient during installation.
