The 4WRPEH6C3B04L-2X/G24K0/A1M-817 valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series to regulate flow and pressure in hydraulic automation circuits. It accepts a ±10 V command input so a controller can deliver proportional positioning without additional signal conditioning. Control symbol C3 defines the spool cut-outs that meter oil in the required direction. A linear flow characteristic ensures the output varies directly with the input, and hysteresis is limited to 0.2 % to maintain repeatability. Electrical power is supplied at 24 V DC through a DIN 43563-AM6 connector that includes six power pins and protective earth for safe grounding. A 2.5 A external fuse guards the supply line against overcurrent faults. If power or command is lost, the spool shifts to its fail-safe state within 7 ms at zero bar, minimizing unintended actuator motion.
An IP65 degree of protection shields the enclosure from dust and water jets encountered in industrial environments. The valve is built to the NG6 nominal size, allowing compact installation on manifolds that follow the ISO 4401-03-02-0-05 pattern. Under rated conditions it delivers 4 l/min at a 70 bar differential, suitable for precise control of small cylinder or motor groups. Working ports P, A, and B withstand pressures up to 315 bar, while the T port is limited to 250 bar, so the return circuit must remain below that threshold. Internal feedback is provided on transducer side B to keep the spool centered on its commanded position. The assembly weighs 2.7 kg, enabling straightforward manual mounting during machine build or service.
