The 4WE6J6X/EG24N9K72L/B10 AN is a valve produced by Bosch Rexroth within the WE Directional Spool Valves series, and it shifts hydraulic flow paths in automated machinery. The solenoid operates on a nominal voltage of 24 V DC and draws 1.25 A, so the coil consumes 30 W during actuation. A voltage tolerance of ±10 % lets the unit accept common supply deviations without malfunction, while a 100 % ED duty cycle allows continuous energization. Thermal limits are set by a coil surface temperature rating of 120 °C, supporting long-term service at elevated ambient heat. The M12×1 four-pin K72L connector simplifies wiring, and pin 4 is assigned to +24 V DC for consistent power routing. An IP65 housing seals the assembly against dust and low-pressure water jets, and a switch-off overvoltage limit of 500 V prevents insulation stress when the coil is de-energized.
Hydraulic capacity is defined by a maximum operating pressure of 350 bar at ports a, b, and p, while the tank port is limited to 210 bar. The valve passes up to 80 l/min of oil in direct current service, providing prompt actuator response without excessive pressure rise. A 1.0 mm throttle insert in port P moderates flow during spool transitions to reduce hydraulic shock in downstream circuits. Installation on subplates is straightforward because the mounting surface follows the ANSI B93.9 porting pattern. By combining the stated flow capacity with the pressure limits, the unit maintains stable directional control without cavitation or leakage across the spool, enabling reliable operation in presses, injection machines, and automated handling stations.
