The 4WE6HA6X/EG24K4QM0G24 valve is produced by Bosch Rexroth within the WE Directional Spool Valves series and is intended to switch hydraulic flow paths in automated machinery. Its nominal size of 6 (NG6) defines the envelope and mounting footprint, and the ISO 4401-03-02-0-05 porting pattern aligns the subplate interface with standard European manifolds. A maximum flow of 80 l/min permits medium-capacity cylinder or motor circuits, while ports a, b, and p tolerate operating pressures up to 350 bar; the tank port t is limited to 210 bar to protect return-line components. The valve is solenoid-actuated with a coil rated at 24 V DC, so it connects directly to common control buses, and its 30 W nominal power defines the heat generated during steady energization. Continuous service is possible because the duty cycle is 100 % (S1), allowing the solenoid to remain powered without enforced cooling breaks.
An electrical connector conforming to DIN EN 175301-803 (K4) streamlines installation and, when mated, yields an IP65 protection class that shields the coil from dust ingress and water jets. The solenoid draws 1.25 A at 24 V DC, a figure used to size power supplies and driver outputs, and the winding is built to insulation class F, enabling a coil surface temperature up to 120 °C without thermal degradation. Position feedback is based on the rest position identified as QM0, and the associated switch requires a 24 V DC supply so monitoring electronics can share the same low-voltage rail as the actuation circuit. For North American manifolds the unit follows the NFPA porting pattern T3.5.1 R2-2002 D03, ensuring interchangeability with D03 subplates in existing panels.
