The 4WE6JA6X/EG24N9K72L AN directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. Designed to shift hydraulic flow paths in automated machinery, it runs with a 100% duty cycle (S1) so continuous energization will not overheat the coil. A rated voltage of 24 V DC and a rated current of 1.25 A match common machine control supplies, while the coil accepts a ±10% voltage fluctuation to tolerate minor line variations. The electromagnet consumes 30 W of nominal power, setting the load presented to power supplies and driver boards. Electrical hookup is through an M12x1 four-pin connector identified as K72L; pin 3 serves as the coil ground and pin 4 carries the 24 V feed, which simplifies plug-and-play wiring. An IP65 enclosure rating keeps dust ingress and low-pressure water jets from entering the solenoid housing so the valve can be mounted near spray zones.
A concealed manual override identified as N9 lets maintenance staff shift the spool locally, and it can safely vent to tank as long as back pressure does not exceed 50 bar. The valve handles line pressures up to 350 bar on ports P, A, and B, while the tank port is limited to 210 bar, fitting standard high-pressure circuits. It passes up to 80 l/min of direct current flow without exceeding rated differential, providing capacity for medium-sized actuators. Switching is limited to 1 Hz with the K72L coil, a frequency that balances response speed against thermal rise during cycling. Port geometry follows the ANSI B93.9 pattern so the unit bolts directly to common subplates without adapter blocks.
