The 4WE6HA6X/EG24N9DK24L2/VSO43A-1791 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and serves to route hydraulic flow in automated systems. Its nominal size of 6 matches compact manifold cavities and establishes the passage area for working fluid. A spool symbol H defines the two-position flow paths needed for cylinder reversal. The valve withstands a maximum operating pressure of 350 bar, permitting use in high-pressure machinery, while a maximum flow of 80 l/min limits velocity to prevent undue pressure drop. Actuation is provided by a wet-pin solenoid that is immersed in hydraulic oil for thermal stability. The coil accepts 24 V DC and draws a rated current of 1.25 A, parameters that align with standard control outputs and dictate conductor sizing. A spring return recenters the spool when power is removed to restore a neutral state. For installation, the body mates with an ISO 4401-03-02-0-05 sub-plate so that replacements remain interchangeable across equipment.
An M12x1 four-pole connector delivers quick electrical coupling and keyed alignment for the control wiring. The housing carries an IP65 ingress rating, sealing the coil against dust and water jets encountered during washdown. NBR sealing elements are used to retain hydraulic fluid and resist common petroleum-based oils. A clamping length of 42 mm specifies the capture distance for the retaining screws, and a tightening torque of 7 Nm secures the body without deforming the mounting face. Protection class III under VDE 0580 keeps the energized components isolated from hazardous voltages. A concealed N9 manual override enables maintenance staff to shift the spool mechanically during setup or fault recovery without energizing the solenoid.
