The 4WRPEH6C3B40L-3X/M/24F1 proportional solenoid valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series. It meters hydraulic flow for automated machinery by converting an analog control signal into spool displacement. The valve is nominal size 6 and incorporates the C3 spool, delivering a linear flow characteristic that simplifies circuit trimming. A rated flow of 40 l/min is available at a 35-bar pressure drop per edge, while the design withstands a maximum operating pressure of 350 bar. Command input is provided as a 4–20 mA current loop, and the internal electronics operate from a 24 V DC supply. Electrical connection uses a 7-pole (6+PE) EN 175201-804 plug, and the housing supplies four ports for connection to system lines.
The device accommodates transient demands up to 50 l/min and offers four switching positions to control complex actuator sequences. It is configured for subplate mounting that matches the ISO 4401-03-02-0-05 pattern; the equivalent NFPA interface is T3.5.1 R2-2002 D03 for interchangeability in North American manifolds. NBR sealing elements protect against standard hydraulic fluids, and overall weight is 3.120 kg to ease installation. With these mechanical and electrical features aligned, the valve maintains accurate response under closed-loop flow or pressure commands in high-pressure circuits.
