The 4WRPEH6C3B04P-2X/G24K0/A1M valve is manufactured by Bosch Rexroth for the 4WRP Solenoid Valves series. It is a size 6 NG6 proportional spool unit that meters hydraulic flow in automation systems. The rated flow is 4 l/min at a 70 bar differential, providing accurate motion control for compact actuators. Working ports P, A and B tolerate pressures up to 315 bar, while the tank port is limited to 250 bar. A C3 spool profile and a P-type inflected flow characteristic shape the metering curve. The electronics accept a ±10 V analog command (interface A1) and present an input resistance of 100 kΩ. Closed-loop hysteresis does not exceed 0.2 %, supporting repeatable positioning across the full stroke.
The valve attaches to an ISO 4401-03-02-0-05 mounting pattern for quick exchange on standard subplates. Solenoid power is 24 V DC and reaches the coils through a DIN 43563-AM6 connector that provides six control contacts and a protective earth. The position transducer is arranged on side B, keeping feedback wiring on the same housing face as the power leads. System fluid must be filtered to ISO 4406 (c) 18/16/13 to prevent contamination-induced wear. The assembly weighs 2.7 kg, allowing single-person handling during maintenance, and the calculated mean time to dangerous failure is 150 years, indicating long functional life in continuous service.
