The 4WE6J6X/EW110NK4/N08V is a directional spool valve produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automation circuits. The solenoid coils are wound for 110 V AC at 50 or 60 Hz, so the valve can be energized directly from standard industrial control transformers. At 50 Hz the magnetic assembly draws 0.52 A, while at 60 Hz the draw falls to 0.39 A, allowing designers to size power supplies accurately. A DIN EN 175301-803 K4 connector mates to the coil housing, simplifying wiring and providing consistent pin orientation. The valve mounts on a manifold with the ISO 4401-03-02-0-05 port pattern, which promotes interchangeability with other NG6 components. It can be installed in any position, giving machine builders freedom to orient the block as needed. The hydraulic section withstands 350 bar on ports P, A, and B, and passes up to 60 l/min, enabling reliable control of medium-flow circuits without exceeding pressure limits.
The enclosure achieves IP65, so it resists dust ingress and water jets when a proper connector is fitted. FKM seals are used to cope with aggressive fluids and elevated oil temperatures. The required oil cleanliness is ISO 4406 class 20/18/15, which limits particle contamination and preserves spool accuracy. Tank port T endures up to 160 bar, supporting circuits where back-pressure is intentionally raised. A mechanical override is fitted, allowing manual actuation during commissioning or power loss, and the override functions safely up to 50 bar tank pressure. With both solenoids installed the assembly weighs 1.95 kg, making it easy to handle during manifold installation. The mean time to dangerous failure is calculated at 300 years, offering a very long reliability window for safety evaluations.
