The 4WRPEH6C3B04L-3X/M/24A1 proportional directional valve is built by Bosch Rexroth for the 4WRP Solenoid Valves series and serves to meter hydraulic fluid in closed-loop automation circuits. Size 6 establishes a compact envelope for manifold mounting, while the C3 spool symbol defines equal metering edges that support bidirectional flow control. A linear flow characteristic ensures that spool travel correlates directly with flow gain, and a rated flow of 4 l/min at a 35-bar differential matches the demands of small-to-medium cylinders. The internal electronics operate from a 24 V DC supply, accept a ±10 V analog command to set spool position, and draw no more than 40 VA, so power supplies can be sized accurately. A 2.5 A external fuse guards the feed line, and a 7-pole (6+PE) EN 175201-804 connector provides a quick, keyed interface.
The valve attaches to systems using the ISO 4401-03-02-0-05 porting pattern, giving compatibility with widely available subplates. Operating pressure can reach 350 bar on ports a, b, and p, enabling high-force actuation, whereas port T is limited to 250 bar to prevent back-pressure damage in the tank circuit. The enclosure meets IP65, so sealed gaskets and the connector keep dust and water spray away from coils and position sensors. Electrical stability is aided by a permitted residual ripple of 2.5 Vpp on the supply, which minimizes unintended spool oscillations. NBR sealing elements contain mineral oil without swelling and simplify routine maintenance. With a mass of 2.9 kg the unit can be handled by one technician and mounted quickly, completing the set of features required for responsive proportional control in industrial hydraulics.
