The 4WE6J9-6X/EG24N9K4 valve is produced by Bosch Rexroth and belongs to the WE Directional Spool Valves series. It directs hydraulic fluid between pressure, actuator, and tank lines to automate motion sequences in machinery. The unit withstands a maximum operating pressure of 350 bar on ports a, b, and p, while the tank port tolerates 210 bar in direct current service. A rated flow of 80 l/min ensures adequate volume for medium-capacity circuits. Actuation is supplied by a high-power wet-pin solenoid energized at 24 V DC, drawing a rated 1.25 A during steady state. The solenoid winding is built to insulation class F and the coil surface temperature is limited to 120 °C for thermal safety. Two solenoids bring the total mass to 1.95 kg, allowing straightforward handling during manifold installation.
For electrical connection, the valve employs a DIN EN 175301-803 K4 plug, and when that connector is fitted the enclosure achieves IP65 ingress protection against dust and water jets. The body can be mounted in any position, giving designers flexibility in stack or sub-plate layouts. A concealed manual override identified by code N9 permits spool shifting during commissioning, and its use is restricted to tank pressures up to 50 bar. The hydraulic interface follows the ISO 4401-03-02-0-05 porting pattern and matches the NFPA D03 mounting footprint, enabling interchange with standard sub-plates. These interface features, combined with the previously noted electrical and pressure limits, define the valve’s role in compact directional control stations.
