The 4WE6J6X/EG24N9K4/B10 UR directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It shifts hydraulic flow paths by energizing a 24 VDC solenoid rated at 1.25 A, so control electronics can operate the valve directly. The coil consumes 34 W at nominal voltage and accepts a ±10 % voltage fluctuation without functional loss. Continuous operation is permitted because the duty cycle is 100 % ED, while the maximum coil surface temperature of 120 °C defines the thermal limit that must not be exceeded. A DIN EN 175301-803 K4 connector provides standardized electrical termination and assists quick replacement during service. Protection against dust and water jets is defined by an IP65 ingress rating, allowing cabinet-free mounting in typical machinery environments. A concealed manual override marked N9 lets maintenance personnel shift the spool mechanically when power is unavailable.
The hydraulic section follows the ISO 4401-03-02-0-05 porting pattern, enabling interchange with other size-03 subplates. During operation ports A, B, and P can be pressurized up to 350 bar, while port T is limited to 210 bar to safeguard return-line components. The valve passes up to 80 l/min of filtered oil in direct-current service, and a 1.0 mm throttle insert in port P moderates inlet flow to improve spool stability. Secure mounting requires tightening M5 screws to 7 N·m so that sealing rings remain compressed under peak pressure. These parameters coordinate to deliver reliable directional control in automated hydraulic circuits.
