The 4WRPEH6C3B02L-2X/G24K0/A1M-816 valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth for hydraulic automation where electronic flow control is required. Nominal size 6 matches compact manifolds while still allowing a nominal flow of 2 l/min at a 70-bar differential, so small actuators can be metered precisely. A linear flow characteristic simplifies controller tuning because spool position changes proportionally adjust volume throughput. The internal spool follows the C3 symbol, defining port interconnections for bidirectional actuator movement. Installation follows the ISO 4401-03-02-0-05 mounting pattern, enabling direct stacking on standardized subplates. Ports p, a, and b withstand working pressures up to 315 bar, whereas the tank port tolerates 250 bar, permitting high power density without overloading return lines. NBR seals are fitted to resist common mineral oils and maintain leak-free service across temperature shifts.
Electrical operation is powered from a 24 V DC supply, and the solenoid draws 40 VA during steady state, so cabinet power budgeting is straightforward. The control amplifier delivers a ±10 V input signal that proportionally drives the spool, enabling closed-loop position or pressure commands. A 6-pole plus protective-earth plug conforming to DIN 43563-AM6 provides the primary interface, and a separate 2.5 A external fuse safeguards the circuit against overcurrent. The unit ships without a plug-in connector, coded K0, leaving the installer free to select a cable exit style that fits the machine layout. Once wired and sealed, the housing achieves IP65 protection, guarding internal electronics from dust and water jets common in pressurized fluid systems. Hydraulic cleanliness must reach ISO 4406 class 18/16/13 to preserve spool accuracy and reduce wear, ensuring long-term performance of the valve assembly.
