The 4WE6D6X/EG24N9K72LSO9 AN directional spool valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require reliable flow direction control. It installs on an ISO 4401-03-02-0-05 interface so it aligns with common subplates, and uses the NFPA T3.5.1 D03 port layout for consistent manifold connections. The coil is rated at 24 V DC, and it accepts a ±10 % voltage swing without performance loss. Under nominal conditions the solenoid draws 1.25 A and consumes 30 W to shift the spool. Electrical hookup is through an M12x1 four-pole connector that includes a suppressor diode to limit inductive kickback. The valve is intended for continuous operation with a 100 % duty cycle, allowing persistent energization in closed-loop systems.
In service the valve handles line pressures up to 350 bar on ports A, B, and P while the tank port withstands 210 bar during direct current actuation. It passes up to 80 l/min of hydraulic oil without exceeding the rated pressure drop. An IP65 enclosure shields the coil and connector against dust and low-pressure water jets, and the design meets VDE protection class III for safety extra-low-voltage circuits. Switching transients are limited to 500 V when the coil is de-energized to protect downstream electronics. A concealed manual override lets maintenance staff shift the spool without power when needed. With two solenoids installed the assembly weighs 1.95 kg, facilitating straightforward mounting on compact actuator blocks.
