The 4WE6E6X/EG24N9K72LSO407 valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation where directional control must be reliable. It installs on the ISO 4401-03-02-0-05 pattern so it can bolt directly to standard subplates, and the clamping length of 42 mm keeps the body firmly seated against the manifold. Electrical actuation is supplied through an M12 × 1 four-pole plug labeled K72L, giving a compact connector that eases field replacement. The solenoid operates at a nominal 24 V DC and draws a rated current of 1.25 A, while a ±10 % voltage window allows stable performance on supplies that fluctuate. Nominal power for the SO407 coil is limited to 8 W to moderate heating under continuous use. These characteristics allow the component to switch flow paths quickly without excessive energy consumption.
A continuous duty cycle of 100 % S1 lets the solenoid remain energized for as long as the control logic demands. The IP65 ingress protection rating seals the enclosure against dust and pressurized water, and a concealed manual override coded N9 lets technicians reposition the spool during commissioning. Coil surface temperature is restricted to 85 °C under the SO407 build, protecting winding insulation during extended holding periods. Hydraulic limits include 315 bar on ports A, B, and P and 210 bar on port T, supporting high-pressure work circuits. The valve passes up to 60 L/min in direct-current service, while switch-off overvoltage is capped at 500 V to avoid controller damage. A switching frequency of two cycles per second maintains responsiveness without overstressing the coil.
