The 4WE6H6X/EG24N9K4/R12V directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and routes pressurized fluid between actuator circuits in hydraulic automation. It is energized by a 24 V DC solenoid so the valve can be driven directly from common machine control power supplies, and the coil draws 1.25 A at that voltage to help engineers size conductors and fuses. A DIN EN 175301-803 form K4 plug provides the electrical connection, allowing quick replacement in the field. Four working ports follow the ISO 4401-03-02-0-05 pattern, making the unit interchangeable with other size 6 subplate devices, while the NFPA T3.5.1 R2-2002 D03 interface secures the body to standard manifolds. The flow capacity reaches 80 l/min in direct current operation, supporting medium-flow circuits without excessive pressure drop. Service pressure on ports P, A, and B is permitted up to 350 bar, and the tank port tolerates 210 bar, enabling high-pressure actuation while protecting return lines.
The valve can be installed in any orientation, which simplifies layout in confined assemblies. IP65 ingress protection keeps dust and water jets out of the coil housing, ensuring reliable switching in harsh environments. Electrical safety meets VDE 0580 protection class I, and the integrated ground path reduces shock risk during maintenance. A concealed manual override identified as N9 lets technicians shift the spool during commissioning without energizing the solenoid. Oil cleanliness must reach ISO 4406 class 20/18/15 to maintain spool clearance and prevent wear. FKM seals marked V resist high temperatures and many hydraulic fluids, extending service life. A 1.2 mm throttle insert in port B, code R12, moderates flow in the B circuit to improve actuator stability.
