The 4WE6J73-6X/EG24N9K4SO407 directional spool valve is part of the WE Directional Spool Valves series from Bosch Rexroth and is used to route hydraulic fluid in automated machinery. It mounts on subplates with the ISO 4401-03-02-0-05 porting pattern so it can drop into standard NG6 circuit cavities. A 24 V DC solenoid actuates the spool, and the ±10 % voltage tolerance keeps performance steady when supply levels drift. The coil draws 8 W, and a 100 % duty cycle lets it remain energized continuously without overheating. Thermal rise is controlled because the coil surface may reach a maximum of 85 °C, while insulation class F on the DC winding resists that temperature. A DIN EN 175301-803 (K4) plug serves as the electrical connector, simplifying field wiring and sealing the housing.
The valve includes a concealed manual override identified by code N9, giving operators a way to shift the spool manually, although the action must be limited to 50 bar on the tank line. Hydraulic ratings reach 315 bar on ports p, a, and b, and the tank port can withstand 210 bar during direct-current actuation, letting the unit run in high-pressure circuits. A maximum flow of 60 l/min defines the throughput capacity, while a switching frequency of two cycles per second enables responsive control loops. The enclosure meets IP65, so internal components are protected from dust ingress and low-pressure water jets in industrial environments. Finally, the valve weighs 1.95 kg, which permits single-person installation and reduces load on compact manifold blocks.
