The 4WE6J6X/EG24N9K4KSO21 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series for hydraulic automation systems that require reliable on-off flow control. It is built in size 6, which defines the port envelope for modular subplate mounting. A J type spool determines the internal flow paths so actuators can be driven in both directions. The valve mounts on the ISO 4401-03-02-0-05 pattern, allowing interchange with other CETOP 3 devices. When energized it passes up to 80 l/min of hydraulic oil, providing sufficient throughput for medium power circuits. Pressure capability reaches 350 bar on the service ports and pump line, while the tank port withstands 210 bar. Continuous operation is supported because the solenoid is rated for a 100 percent duty cycle. Control power is supplied at 24 V DC, and the coil accepts a ±10 percent voltage variation without performance loss.


The solenoid draws a rated current of 1.25 A, which corresponds to a nominal power consumption of 30 W during steady excitation. A K4K connector according to DIN EN 175301-803 provides the electrical interface for quick field wiring. The enclosure carries an IP65 rating, so sealed housings and gaskets prevent dust ingress and water jets. Protection class I under VDE 0580 requires a protective ground connection for safe operation. A concealed manual override identified by code N9 lets service personnel shift the spool mechanically when power is unavailable. Dynamic sealing is handled by NBR elastomers to ensure compatibility with standard mineral oils.
