The 4WE6H6X/EG24N9K72L AN directional spool valve is part of the WE Directional Spool Valves series produced by Bosch Rexroth for controlling actuator movement in hydraulic automation. It is built in size 6 to fit compact manifolds while still handling up to 80 l/min of direct current flow, supporting rapid cycle times. The valve bolts to an NFPA D03 interface so it can drop into standard subplates, and its port arrangement follows ANSI B93.9 to keep passage alignment consistent across brands. Working ports A, B, and P are rated for 350 bar, giving headroom for high-pressure circuits. A concealed manual override identified by N9 lets maintenance staff shift the spool when the solenoid is de-energized while preventing accidental actuation. Continuous energization is permitted because the coil is designed for a 100 % duty cycle, and it accepts a 24 V DC supply that may fluctuate within ±10 % without performance loss.
Electrical input is provided through an M12×1 four-pin connector coded K72L, simplifying plug-in replacement during service. At the rated 24 V level the coil draws 1.25 A and converts this input to a nominal 30 W, producing magnetic force to shift the spool without overheating. The return line at port T can withstand 210 bar, so back-pressure spikes from long hose runs do not compromise sealing. An IP65 enclosure resists dust and low-pressure water jets, allowing installation on mobile or wash-down equipment. The valve meets VDE protection class III requirements, meaning its electrical circuit operates on safe extra-low voltage to minimize shock hazards in moist environments.
