The 4WE6W73-6X/EG24N9DK24L2A12ZV62SO43A-1791 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It mates with subplates that use the ISO 4401-03-02-0-05 porting pattern and carries a nominal size of 6. The flow path supports up to 80 L/min while holding 350 bar on pressure ports P, A, and B, and 210 bar on the tank port, providing dependable control in medium-pressure systems. Switching is handled by a solenoid that reaches 4.2 cycles per second for responsive actuation. The coil accepts 24 V DC and stays within specification across a ±10 % voltage window. Connection is made through an M12×1 four-pin plug assigned to the DK24 version, and a concealed N9 manual override allows spool movement during setup or maintenance without exposing moving parts.
The valve’s electromagnetic assembly draws 30 W and is rated for a 100 % duty cycle, allowing continuous energization without mandatory cooling pauses. Coil insulation is safeguarded by a maximum surface temperature limit of 120 °C, which maintains reliability during prolonged service. A clamping length of 22 mm streamlines stacking with adjacent sandwich valves, and the body can be installed in any orientation to fit confined control blocks. FKM seals resist common hydraulic fluids and additives, preventing external leakage and internal cross-port contamination. These construction details ensure stable directional control in hydraulic automation where round-the-clock operation and compact mounting are required.
