The 4WE6D6X/EG24N9K72L/V AN directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits and is energized by a 24 V DC supply at a rated current of 1.25 A, resulting in a nominal coil power demand of 30 W. Continuous energization is permitted because the electromagnetic assembly is rated for a 100 % duty cycle. The coil surface may reach 120 °C under sustained load, so mounting must accommodate thermal clearance. Command signals reach the solenoid through an M12×1 four-pin connector identified by coding A, allowing quick plug-in installation. An IP65 enclosure guards the windings and terminals against dust ingress and low-pressure water jets in typical industrial environments. Actuation is limited to 1 Hz, a switching frequency that prevents excessive heat while supporting normal directional control sequences.
In operation the spool can withstand system pressures up to 350 bar at the P and A ports, while the T return line is limited to 210 bar when handling direct current control. The hydraulic body ships with a maximum flow capacity of 80 L/min, supporting medium-size actuator circuits without excessive pressure drop. Internal channels follow the ANSI B93.9 porting pattern, simplifying manifold block machining and replacement of earlier valves with the same footprint. A concealed manual override designated N9 permits local movement of the spool during commissioning or power loss. Fluid cleanliness should be maintained at ISO 4406 class 20/18/15 to prevent wear on sliding surfaces. External seals are made of FKM, providing compatibility with most mineral oils and higher-temperature synthetic fluids.
