The 4WE6H6X/EG24N9K4/A12/62SO43A-1019 directional spool valve is supplied by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic oil to selected actuator ports in automated machinery. The size 6 body accommodates compact manifold layouts, while the ISO 4401-03-02-0-05 porting pattern matches common sub-plates used in industrial power units. A maximum operating pressure of 350 bar lets the P, A, and B passages control high-pressure circuits, and a tank port limit of 210 bar prevents back-pressure damage on return lines. The solenoid can pass up to 80 l/min, so flow capacity is suitable for medium-duty cylinders and motors. Electrical drive is provided by a 24 V DC coil that draws 1.25 A within a ±10 percent voltage window, ensuring predictable force on the spool. Nominal power is 30 W, allowing continuous energization without excessive heat buildup.


Continuous service is supported by a 100 percent duty cycle, meaning the coil may remain energized indefinitely during repetitive control sequences. Connection is made through a DIN EN 175301-803 plug (designation K4), and the assembled housing achieves an IP65 rating so sprayed oil or dust cannot enter the electrical chamber when the gasket is fitted. Insulation class F materials protect the winding against temperatures up to 155 °C, while the actual coil surface is limited to 120 °C to keep nearby hoses safe. A concealed manual override labeled N9 lets maintenance staff shift the spool without energizing the solenoid during setup or fault finding. The valve can switch up to 4.2 times per second, enabling rapid on-off modulation in servo-type loops that need quick directional changes.
