The 4WRPEH10C3B50L-20/G24K0/F1M proportional solenoid valve is manufactured by Bosch Rexroth within the 4WRP Solenoid Valves series. It serves in hydraulic automation systems by metering flow and directing pressure to actuators. The unit is built in valve size 10 (NG10) and mounts on manifolds that follow the ISO 4401-05-04-0-94 pattern. A rated flow of 50 L/min is available at a differential pressure of 70 bar, while the pressure and work ports tolerate up to 315 bar and the return port handles 250 bar. Spool position is commanded by a 4–20 mA input under the F1 signal format, and the coil can run continuously because the duty cycle is 100 % ED. Dynamic performance is defined by a 25 ms response from 0 % to 100 % stroke, and repeatability is supported by hysteresis not exceeding 0.2 %.
The electronics require a nominal 24 V DC supply and disengage below 18 V DC to avoid uncontrolled motion during voltage dips. The circuit draws no more than 60 VA and accepts a ripple of up to 2 V DC without disturbing spool stability. A 200 Ω shunt resistor is included so technicians can monitor coil current without interrupting the loop. The enclosure meets the IP65 protection class, sealing the assembly against dust and low-pressure water jets. Total weight is 7.1 kg, offering sufficient mass to resist vibration while remaining manageable for a single installer.
