The 4WE6E6X/EG24N9DK24L2SO43A-1791 directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow to cylinders or motors in automated machinery. The valve is built in size 6, allowing integration with NG6 subplates, and follows the NFPA T3.5.1 D03 mounting pattern so it fits standard manifolds. Ports are arranged according to ISO 4401-03-02-0-05, which ensures interchangeability with other NG6 components. Electrical actuation relies on a 24 V DC coil that draws 1.25 A, providing consistent shifting force. The coil uses a wet-pin, detachable design to simplify replacement without opening the hydraulic envelope, and it connects through an M12×1 four-pole plug coded DK24 for quick wiring. Thermal protection is supported by insulation class F materials around the coil windings.
During operation the valve tolerates 350 bar on pressure, A, and B lines and 210 bar on the tank port, enabling use in high-pressure circuits. It passes up to 80 L/min without excessive pressure drop, meeting the flow demands of medium-sized actuators. System oil must meet ISO 4406 cleanliness level 20/18/15 to prevent spool wear and sticking. The coil surface may reach 120 °C under maximum duty, so adjacent components should be rated accordingly. An IP65 housing guards against dust and water jets, allowing installation in industrial environments. Orientation is unrestricted because the design permits any mounting position. A concealed manual override identified by code N9 lets maintenance staff shift the spool during power loss without disturbing normal operation, and its hidden placement reduces the chance of accidental actuation.
