The 4WE6W6X/EG24N9K72L/62SO407 AN valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth to direct hydraulic flow in automated machinery. It follows the ANSI B93.9 porting pattern to match industry standard subplates. The solenoid operates on 24 V DC and tolerates a ±10 % supply variation to handle common voltage dips and rises. A nominal power draw of 8 W keeps electrical load modest, while a 100 % ED duty cycle permits continuous energizing without overheating. Wiring is completed through an M12×1 four-pole plug coded A, simplifying quick-disconnect installations. The housing carries an IP65 rating that blocks dust and low-pressure water jets in factory environments. Coil windings are built to insulation class F so thermal stress is managed safely. A concealed manual override labeled N9 allows technicians to shift the spool manually during commissioning or power loss.
The coil surface temperature is limited to 85 °C under SO407 conditions, preventing heat damage to insulation and nearby components. The valve passes up to 60 l/min when energized with direct current, supporting medium-flow actuators. Ports P, A, and B withstand 315 bar, and the tank port handles 210 bar, enabling use in high-pressure return-line circuits. Spool actuation can occur at rates up to two cycles per second, matching the 2 1/s maximum switching frequency. Fluid containment relies on NBR seals that resist standard mineral hydraulic oils. A mean time to dangerous failure of 300 years indicates a long functional safety horizon for critical installations.
