The 4WRPEH6K3B50P-2X/G24K0/A1M valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth. It meters hydraulic flow for closed-loop position or pressure control in automated machinery. The unit is configured in size NG6, which defines the envelope and compatible manifold pattern for small circuits. A subplate mounting style allows removal without disturbing pipework, while the ISO 4401-03-02-0-05 porting pattern aligns pressure, tank, and actuator lines with standard NFPA D03 blocks. The maximum operating pressure on P, A, and B ports reaches 315 bar so the valve can handle typical power unit outputs, and the T port is limited to 250 bar to protect return lines. A non-linear flow characteristic labeled P provides progressive spool response suited to proportional command loops. NBR seals are used to resist common mineral oil fluids, and the complete assembly weighs 2.7 kg, light enough for compact manifold stacks.
The electronics are powered from a 24 V DC supply, and the integrated amplifier accepts a ±10 V command signal so motion controllers can drive the spool directly. An input resistance of 100 kΩ minimizes load on the control card, while total power consumption stays below 40 VA to limit cabinet heat. The circuitry tolerates up to 40 V DC without damage, adding safety margin during switching transients that occur in mobile or plant power rails. A 6 + PE connector in accordance with DIN 43563-AM6 provides the electrical interface and includes a protective earth conductor for safety bonding. When the connector is secured, the valve attains an IP65 rating, enabling installation in wash-down zones where water and dust are present. A fast-acting 2.5 A external fuse is specified to isolate the supply under short-circuit conditions and protect the onboard driver stage against overcurrent.
