The 4WE6EA6X/OFEW110N9K4 valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automation circuits by shifting a size 6 spool that connects or blocks subplate ports as required. High-power wet-pin solenoids move the spool, and they accept a 110 V AC supply so wiring can come directly from standard control transformers. The K4 connector per DIN EN 175301-803 provides a quick electrical interface for these coils. A mounting surface conforming to ISO 4401-03-02-0-05, also known as the NFPA D03 pattern, lets the unit bolt to common manifolds without adapter plates. Passage geometry supports up to 60 L/min, satisfying moderate actuator demands while keeping the body compact. With both solenoids installed the assembly weighs 1.95 kg, enabling single-person installation.
It continues using concealed manual overrides designated N9 so maintenance staff can shift the spool during commissioning without energizing the solenoids. Working lines A, B, and P tolerate 350 bar, while the tank return paths withstand 160 bar back-pressure, allowing use in high-pressure presses or mobile machines. An IP65 enclosure rating prevents dust ingress and protects against water jets so the valve can mount near wash-down zones. The coils draw 0.52 A at 50 Hz and 0.39 A at 60 Hz, limiting cabinet fuse sizes. Internal suppression allows the windings to endure switch-off voltage peaks up to 500 V, guarding insulation from transient surges. These characteristics provide reliable directional control in hydraulic automation systems that require quick response and robust electrical performance.
