The 4WE6L6X/EG12N9K4/V directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. The unit routes pressure fluid to actuator ports in hydraulic automation where compact mounting and rapid switching are required. It is built to nominal size 6, allowing installation on subplates with the ISO 4401-03-02-0-05 interface. The internal spool follows symbol L, so flow paths open and close in a specific overlap pattern suited to meter-in control. The hydraulic end withstands operating pressures up to 350 bar on ports A, B, and P, while the return line can be pressurized to 210 bar at port T. A maximum flow rate of 80 l/min can be directed without exceeding pressure loss limits. FKM seals are fitted to tolerate higher fluid temperatures and aggressive media, and the assembly with two solenoids weighs 1.95 kg for easy handling during manifold service.
In the electrical section the valve employs a DIN EN 175301-803 connector coded K4, and the coupling gains IP65 protection when the gasket is properly installed. The coil is designed for continuous duty at 100 percent ED, drawing 2.5 A from a 12 V DC supply to produce the magnetic force needed to shift the spool. With a nominal power of 30 W, heat rise stays within insulation class F limits so the device can operate in warm machine rooms without premature degradation. A concealed N9 manual override lets maintenance personnel shift the spool mechanically when control voltage is absent, yet prevents inadvertent operation during normal service. These electrical attributes complement the hydraulic ratings described earlier and allow the valve to integrate into mobile or industrial manifolds that require reliable on-off flow control around the clock.
