The 4WE6D73-6X/EG12N9K4SO892 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. Designed to switch hydraulic lines in automated circuits, it houses a D73 spool in a size 6 body that shifts when the solenoid is energized. The coil operates on 12 V DC and draws 2.5 A, while a K4 connector compliant with DIN EN 175301-803 streamlines wiring. A spring return moves the spool back to neutral once power is removed, improving circuit safety. NBR sealing elements retain fluid and resist common mineral oils. The subplate interface follows ISO 4401-03-02-0-05 and matches the NFPA D03 pattern, allowing the valve to replace legacy units without manifold changes.
The unit tolerates pressures up to 350 bar on the work ports and 210 bar on the tank port, supporting medium-pressure machines such as presses and tooling lines. It accommodates a direct current flow of 80 l/min, so actuator speed is not limited by the valve. An IP65 ingress rating shields the coil and connector from dust and low-pressure water jets, enabling installation near spray zones. Coil surface temperature can reach 120 °C during continuous duty, so surrounding components must withstand that heat. A concealed N9 manual override lets maintenance staff shift the spool mechanically without energizing the coil, providing troubleshooting capability while keeping the actuator protected against dirt.
