The 4WE6G6X/EG240N9K4/V directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs pressurized oil to actuators in hydraulic automation. With a nominal size of 6, the valve fits compact subplates while still accommodating required flow. Its ISO 4401-03-02-0-05 (NFPA D03) porting pattern maintains interchangeability across standard manifolds. Four main ports handle pressure supply, two work lines, and tank return to complete a typical closed-center circuit. Ports P, A, and B withstand operating pressures up to 350 bar, so the unit can be placed in high-pressure loops. A concealed N9 manual override enables local shifting when power is absent, and a 50 bar limit on the tank line protects the seat during this operation. Correct installation requires 7 Nm mounting screw torque, and a 42 mm clamping length ensures full thread engagement on the subplate.
For electrical integration, the K4 connector conforming to DIN EN 175301-803 attaches directly to the coil and simplifies field wiring, while a ±10 percent voltage tolerance keeps actuation consistent under supply variations. The solenoid is rated for a 100 percent duty cycle, so it can remain energized indefinitely, yet its surface temperature must stay below 120 °C to prevent insulation damage. The IP65 protection class shields internal components from dust ingress and water jets, allowing use in exposed machine areas. Because the valve can be mounted in any position, designers can orient lines for optimum hose routing. FKM seals combat chemically aggressive hydraulic fluids and elevated temperatures to maintain leak-free service. Finally, a weight of 1.95 kg for the two-solenoid version minimizes load on small manifolds and eases manual handling during maintenance.
