The 4WE6J6X/EW24N9K4/B10 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and routes hydraulic flow to actuators in automation circuits. The component handles pressure up to 350 bar on ports P, A, and B, enabling use in high-pressure power units, while return port t is limited to 210 bar under direct-current operation so tank line sizing must respect this cap. A continuous flow rating of 80 l/min defines the maximum volume it can direct without excessive pressure drop. Installation follows the ISO 4401-03-02-0-05 mounting pattern, which allows interchange with standard sub-plates. The enclosure meets IP65, preventing dust ingress and low-pressure water sprays in harsh machine environments. Fluid contamination must not exceed ISO 4406 class 20/18/15 to avoid spool sticking. With both solenoids fitted the valve weighs 1.95 kg, light enough for manifold stacking. A manual override tolerates tank pressure up to 50 bar, letting maintenance personnel shift the spool during setup or power loss.
Electrical control relies on a 24 V DC coil that draws a rated current of 1.25 A, matching common mobile and industrial supply buses. The magnetic assembly consumes 30 W at nominal voltage, which determines panel heat calculations. An EN 175301-803 plug coded K4 provides the connector interface, simplifying wiring with molded cable sets. The coil can remain energized continuously because the duty cycle is 100% ED, eliminating rest periods in cyclic machinery. Supply variation of ±10% is permitted, so the driver may fluctuate between 21.6 and 26.4 V without loss of function. Internal suppression limits switch-off overvoltage to 500 V, protecting drive electronics from inductive spikes. The hydraulic inlet includes a 1.0 mm throttle insert in port P, which moderates acceleration of the connected actuator. These electrical and hydraulic features together maintain consistent spool response across the specified operating envelope.
