The 4WE6D6X/EG24N9DK24L2/V/62SO43A-1791 valve is produced by Bosch Rexroth within the WE Directional Spool Valves series to route hydraulic flow in automated machinery. A maximum operating pressure of 350 bar on ports a, b, and p allows the spool to control high-pressure circuits, while a maximum direct-current flow of 80 l/min defines the throughput the manifold can accommodate. The ISO 4401-03-02-0-05 porting pattern matches common subplates so installation does not require adapter blocks. A 24 V DC nominal coil voltage and a rated current draw of 1.25 A specify the power supply needed for dependable shifting. The 4-pole M12×1 electrical connector provides a quick-disconnect interface that maintains contact integrity during vibration. A concealed manual override lets maintenance staff move the spool without energizing the coil yet stays recessed to avoid accidental use. With both solenoids installed, the assembly weighs 1.95 kg, a value that influences manifold and panel load calculations.
An IP65 ingress protection rating prevents dust and low-pressure water jets from reaching the coil, and insulation group III per VDE 0580 defines the dielectric spacing inside the winding. The coil surface is permitted to reach up to 120 °C, so thermal checks must confirm ambient and duty cycle limits. FKM sealing elements tolerate mineral oil and elevated temperatures, supporting long service life in aggressive fluids. Fluid cleanliness must not exceed ISO 4406 20/18/15 to keep the spool lands free of abrasive wear. Return-line back-pressure can rise to 210 bar on port t in direct-current service without impairing function. A mean time to dangerous failure of 300 years gives a reliability figure for safety assessments. The ISO 8752-3×8-St locating hole centers the body on the subplate, ensuring precise alignment of pressure passages during assembly.
