The 4WRPEH6C4B25P-2X/G24K0/A1M valve is manufactured by Bosch Rexroth within the 4WRP Solenoid Valves series and serves as a proportional flow controller for hydraulic automation tasks. It follows the ISO 4401-03-02-0-05 mounting interface and occupies nominal size 6, enabling straightforward installation on NG6 manifolds. At a 70 bar differential the unit delivers a rated flow of 25 l/min, and it tolerates working pressures up to 315 bar on ports P, A, and B while the tank line is limited to 250 bar. Dynamic behavior is supported by a response time of 10 ms or less for a full 0–100 % command change. Control repeatability benefits from hysteresis not exceeding 0.2 %, and the enclosure meets the IP65 protection level for resistance to dust and water spray.
The control electronics require a nominal supply of 24 V DC and can withstand up to 40 V DC; ripple on this line must remain below 2 V DC to maintain stable spool positioning. Command input is a differential ±10 V signal presented to an amplifier with 100 kΩ input impedance, minimizing loading on upstream controllers. A 2.5 A external fuse guards the supply circuit, and overall power consumption is limited to 40 VA during continuous operation. The valve weighs 2.7 kg, so a single technician can mount it without additional lifting equipment. Operating within these electrical limits, the proportional solenoid generates precise magnetic force for consistent flow modulation in fast industrial cycles.
