The 4WE6J6X/EG24N9K4/B18 UR directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs pressurized fluid to actuators in hydraulic automation circuits. A 24 V DC solenoid coil operates the spool, and the ±10 % voltage tolerance keeps performance consistent when supply levels vary. The coil draws 34 W, allowing power supplies to be sized accurately, while a 100 % duty cycle lets the solenoid remain energized continuously without overheating. Electrical connection is made through a plug conforming to DIN EN 175301-803 K4, which provides IP65 protection when mated. The valve’s NG6 body matches the ISO 4401-03-02-0-05 porting pattern for straightforward mounting on standard subplates. Four ports link pressure, tank, and two work lines, and an internal spool identified by symbol J establishes the flow paths needed for typical cylinder extend-retract control.
A concealed manual override designated N9 lets technicians shift the valve locally during setup while shielding the push pin from dirt. The assembly supports a maximum flow of 80 l/min, ensuring adequate passage for medium-size actuators. Ports P, A, and B are rated to 350 bar, so the unit tolerates high system pressures, whereas the tank port T is limited to 210 bar to protect return-line components. NFPA size D03 identifies the same mounting footprint for North American manifolds, aiding interchangeability across geographical standards. NBR sealing material resists mineral oil and maintains elasticity under the specified pressure range, and the concealed override combined with these seals supports reliable commissioning and extended service intervals.
