The 4WE6J6X/EW230N9K4/B08N08 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and routes hydraulic flow in automated circuits. Its solenoid coil operates on 230 V at 50 or 60 Hz, drawing 0.23 A at 50 Hz and 0.17 A at 60 Hz so circuit protection can be sized accurately. Continuous energization is possible because the coil is rated for a 100 % duty cycle, preventing heat buildup during long holding periods. Switch-on power reaches 220 VA and then drops to a 50 VA holding level to save energy once the spool has shifted. The design permits two switching actions per second, a frequency that balances response with wear. A concealed manual override identified by code N9 lets maintenance staff move the spool without power. Wiring is completed through a 3-pole DIN EN 175301-803 connector coded K4, allowing straightforward plug-and-socket installation.
An IP65 enclosure keeps dust and water jets away from internal components when the connector is properly sealed. Flow passages accommodate up to 60 l/min, making the unit suitable for medium-capacity actuators. Ports P, A, and B withstand 350 bar, while the tank port tolerates 160 bar, so high-pressure circuits can return fluid safely. Mounting follows the ISO 4401-03-02-0-05 pattern, ensuring interchangeability with standard CETOP 03 subplates. A 0.8 mm throttle insert in the P supply line and identical 0.8 mm inserts in the A and B work ports limit surge flow and damp pressure spikes. These restrictions complement the rated flow and pressure limits to reduce hydraulic shock during rapid spool changes, resulting in precise electrically controlled switching performance.
