The 4WE6M6X/EG24N9K4/B10V directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation circuits. It conforms to nominal size 6, matching compact ISO 03 manifolds, and follows the ISO 4401-03-02-0-05 porting pattern for straightforward mounting. Electrical actuation is provided by a 24 V DC coil that draws 1.25 A, supplying steady magnetic force to shift the spool. The coil terminates through a DIN EN 175301-803 K4 connector for standardized wiring. A housing rated at IP65 shields internal parts against dust and water when the plug is correctly installed. The N9-coded concealed manual override allows local shifting without energizing the solenoid while reducing the risk of accidental activation. Thermal operation is limited by a maximum coil surface temperature of 120 °C, so enclosure ventilation can be planned accordingly.
The valve requires hydraulic fluid cleanliness of 20/18/15 per ISO 4406 to avoid abrasive damage and sticking. When the manual override is engaged, the tank line may see pressures up to 50 bar without exceeding design limits. During powered operation it manages flows up to 80 l/min and withstands 350 bar at ports A, B, and P, while the tank port tolerates 210 bar. FKM seals resist oil swelling and high temperatures, securing the spool against external leakage. Flow in port B can be moderated by a throttle insert with a 1.0 mm orifice to slow actuator motion under specific circuit requirements.
