The 4WE6D6X/EG125N9K4QMAG24/V is a directional spool valve manufactured by Bosch Rexroth for the WE Directional Spool Valves series, intended to switch hydraulic flow paths in automated machinery. The valve handles up to 80 l/min, accommodating medium flow circuits without excessive pressure drop, and it withstands operating pressures as high as 350 bar for use on high-pressure lines. Interface compatibility is provided by the ISO 4401-03-02-0-05 porting pattern, and it mounts to NFPA D03 cavities specified by T3.5.1 R2-2002. A concealed N9 manual override lets technicians shift the spool when the solenoid is not energized, while a QM position sensor reports spool location A to the controller for status feedback. FKM seals resist heat and aggressive hydraulic fluids, and the solenoid can remain energized continuously because it is rated for a 100 % ED duty cycle in operating mode S1.
Electromagnetic actuation is delivered by a 125 V DC coil that draws 0.17 A, resulting in a nominal power demand of 30 W. The winding is built to insulation class F and may reach a surface temperature of 120 °C without degradation. Electrical connection uses a DIN EN 175301-803 plug coded K4 for quick wiring, and a 24 V monitor supply enables the machine control system to observe coil status. Secure installation is achieved with four M5 × 50 screws tightened to 7 Nm, keeping the valve seated under full system pressure. These characteristics allow the unit to operate reliably in continuous-duty hydraulic automation tasks.
