The 4WRPE6W18SJ-2X/G24K0/F1M proportional solenoid valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series and meters hydraulic flow to actuators in closed-loop automation circuits. A nominal size of 6 supports manifold assemblies where NG6 cavities are used, and a nominal flow of 18 l/min allows stable actuator velocity at moderate system rates. Its progressive flow characteristic gives fine resolution at low openings so position control remains smooth. Command signals of 4, 12, or 20 mA are accepted at the setpoint input, enabling direct interface with common current-loop controllers. Internal electronics operate from a 24 V DC supply voltage, simplifying power distribution in mobile or stationary machinery. Dynamic behavior is characterized by a 20 ms response time for a 100 % step, which limits overshoot during rapid command changes, while hysteresis is held below 0.3 % to provide repeatable positioning when the command returns to the same value.
Ambient operation is permitted from −20 °C to +50 °C so the valve can be installed in outdoor or unconditioned plant areas. An IP65 degree of protection shields internal components against dust and low-pressure water jets, supporting reliable service on exposed machinery. The molded plug connector uses a 6 P + PE interface according to DIN 43563, delivering secure electrical termination and a dedicated protective-earth pin. Hydraulic installation follows the ISO 4401-03-02-0-94 mounting pattern, allowing interchange with other NG6 directional elements. The unit tolerates working pressures up to 315 bar in ports P, A, and B, while port T is limited to 200 bar to match common return-line ratings. NBR seals confine fluid in mineral-oil circuits and resist wear under cycling pressure, and the assembly weighs 3.9 kg, light enough for direct stack mounting without additional support.
