The 4WE6D6X/OFEG24N9DK24L2/62SO43A-1750 valve is produced by Bosch Rexroth in the WE Directional Spool Valves series and shifts hydraulic flow between actuator ports in automated machinery. The unit fits systems built around nominal size 6 cavities, and it mates to subplates through the ISO 4401-03-02-0-05 mounting pattern for dimensional interchangeability. A maximum operating pressure of 350 bar on ports A, B, and P lets the valve serve high-pressure work circuits, while the tank port tolerates 210 bar during pressure spikes. Flow capacity reaches 80 l/min to support medium-duty cylinder or motor speeds. The design accepts fluids with viscosities from 2.8 to 500 mm²/s, so it works with most mineral oils used in industrial plants. Continuous service is permitted from −20 °C to +80 °C, covering cold starts and elevated reservoir temperatures, and supplied oil must meet ISO 4406 cleanliness class 20/18/15 to prevent spool sticking.
Actuation is provided by wet-pin high-power solenoids that deliver strong shifting force for reliable spool positioning. Each coil is energized with 24 V DC and draws 1.25 A, simplifying connection to machine control cabinets. Power reaches the coils through an M12×1 four-pin DK24L connector that supports quick exchange without rewiring. The enclosure carries an IP65 rating, so the valve resists dust ingress and water jets on exposed equipment. A concealed N9 manual override lets maintenance staff move the spool without energizing the solenoid, and the OF detent version omits a spring return so the spool stays in its last commanded position after power loss. Total assembly mass with two solenoids is 1.95 kg, light enough for compact manifold stacks and robotic end-effectors.
