The 4WE6J73-6X/EG24N9K72L/A12/62 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for controlling flow direction in hydraulic automation systems. It operates on a 24 V DC supply, and the solenoid accepts a voltage swing of ±10 % to tolerate line variation. Current draw is 1.25 A, producing a 30 W electromagnetic load that shifts the spool with reliable force. Continuous energization is possible because the coil is rated for a 100 % ED duty cycle, and its surface may reach up to 120 °C without damage. Wiring is completed through an M12×1 four-pin connector coded K72L, simplifying installation and service. The enclosure carries an IP65 rating, so dust ingress and low-pressure water jets do not affect internal components.
The hydraulic interface follows the ISO 4401-03-02-0-05 porting pattern, allowing direct mounting to common CETOP 3 subplates for compact manifold layouts. The spool conducts up to 80 l/min while withstanding 350 bar at pressure and work ports, and the tank port endures return pressures up to 210 bar. Switching tasks are limited to one actuation per second, matching circuits that require dependable but moderate cycling rates. A concealed N9 manual override lets maintenance personnel reposition the spool when electrical power is unavailable. Assembly alignment is maintained by a locating hole built to ISO 8752-3×8-St, securing the body against rotation during bolt tightening. This standardization shortens downtime because technicians can replace the valve without special adapters.
