The 4WRPEH6C4B12L-2X/G24K0/A1M valve sits in the 4WRP Solenoid Valves series from Bosch Rexroth and serves as a proportional control element for hydraulic automation loops. It uses a nominal size NG6 interface and follows the ISO 4401-03-02-0-05 mounting pattern, allowing direct installation on standard subplates. A linear flow characteristic combines with a nominal flow rating of 12 l/min to meter fluid in a predictable way during actuator positioning. The unit accepts working pressures up to 315 bar on ports P, A, and B, while the tank port tolerates 250 bar, so circuit designers can place it in medium-to-high pressure manifolds. Dynamic performance is maintained through a response time of 10 ms or less, and repeatability is supported by hysteresis kept below 0.2 percent.
Electrical circuitry is supplied with 24 V DC, and command signals are interpreted through a ±10 V setpoint input that sees 100 kΩ input impedance to avoid loading the controller output. Peak power demand does not exceed 40 VA, and over-current protection is provided by a fast-acting 2.5 A external fuse. Field wiring terminates on a 6P+PE connector conforming to DIN 43563, while the enclosure achieves an IP65 rating to block dust ingress and low-pressure water jets. NBR seals contain hydraulic media and resist common mineral oils used in industrial systems.
