Bosch Rexroth 4WRPEH6C4B25P-3X/M/24A1 proportional directional valve

4WRPEH6C4B25P-3X/M/24A1 is a factory-listed size 6 direct-operated proportional directional valve with electrical spool-position feedback and integrated electronics. Material number R901382361 identifies the existing execution. It uses spool symbol C4, inflected metering and 25 L/min nominal flow at a pressure differential of 35 bar per control edge. The A1 interface accepts a ±10 V command; the electronics require 24 VDC nominal supply. NBR seals must be compatible with the selected hydraulic fluid.

The applicable series limits distinguish 350 bar at P, A and B from 250 bar at T. Transition to the fail-safe position is additionally limited to 250 bar across the summed metering edges for this spool and rated-flow execution. De-energization is not leakage-free isolation; consider the manufacturer’s leakage and transient-motion information. Curve tests use HLP46 at 40 ±5 °C. Article-listed maximum flow is separate from nominal flow and does not establish a complete operating envelope. Mating connectors, subplates and mounting screws are separate-order accessories.
