The 4WE6HA6X/EG24N9DK35LSO407 valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series and is used to shift hydraulic flow paths in automated machinery. A cleanliness class of 20/18/15 per ISO 4406 is required so the spool can move without particle interference. The mounting interface follows porting pattern ISO 4401-03-02-0-05, which simplifies installation on standard subplates. A 24 V DC solenoid with a voltage tolerance of ±10 percent drives the valve, drawing only 8 W and minimizing panel heat. Continuous duty is allowed by a 100 percent ED rating, and insulation class F withstands the resulting temperature rise; coil surface temperature may reach 85 °C under maximum load. The electrical connection is an M12 × 1 four-pole plug coded DK35L for quick cable replacement. An IP65 enclosure blocks dust and water jets, while protection class III to VDE 0580 maintains extra-low-voltage isolation.
Hydraulic capability matches medium-pressure circuits: service and pressure ports a, b, and p tolerate 315 bar, whereas the tank port t is limited to 210 bar when the unit is powered by direct current. A maximum flow of 60 L/min lets the valve handle moderate volumes without excessive drop. A concealed manual override labeled N9 gives technicians a way to shift the spool during setup, but it may be used only when tank pressure is below 50 bar. Because the coil can remain energized continuously, the pressure and flow limits are coordinated with thermal behavior to keep response stable throughout long production runs. These hydraulic figures define the safe working envelope for cylinders, motors, and accumulators connected to the valve, ensuring reliable directional control in presses, machine tools, and other equipment that operates around the clock.
