The 4WE6D6X/EG24N9DK24L2/B10 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes pressurized fluid to control cylinders or motors in hydraulic automation. It uses the ISO 4401-03-02-0-05 porting pattern so it can be mounted on common NG6 subplates. A maximum operating pressure of 350 bar at ports P, A, and B lets the unit work in high-pressure circuits, while the tank port is limited to 210 bar to protect return-line components. The valve passes up to 80 l/min of flow, supporting medium-capacity drives, and a 1.0 mm throttle insert in port P moderates pressure surges. Fluid cleanliness must reach ISO 4406 code 20/18/15 to minimize spool wear. The enclosure is rated IP65, enabling installation where dust and water jets are present. A concealed N9 manual override allows local actuation during setup, and this feature is restricted to 50 bar tank pressure to prevent seal damage.
The solenoid coil operates from a 24 V DC supply so it can be driven directly from safety extra-low-voltage controllers; the rated current is 1.25 A, allowing simple sizing of power outputs. Electrical connection is made with an M12×1 four-pole plug, providing quick, keyed wiring in tight panels. The coil surface may reach 120 °C under continuous duty, which matches the F insulation class assigned to the winding. Overall electrical safety is classified to Protection Class III, limiting the device to low-voltage systems without additional grounding. A mean time to dangerous failure of 300 years demonstrates a very high reliability level for long-life machinery. These electrical characteristics complement the hydraulic data listed earlier and define the operating limits for dependable service.
