The 4WE6J6X/EG24N9K4/B10SO43A-1755 valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that require compact directional control. It fits a nominal size 6 mounting interface and follows the ISO 4401-03-02-0-05 porting pattern so it can be bolted to standardized sub-plates. Electrical actuation is supplied with a nominal voltage of 24 V DC, and the coil will accept a ±10 % voltage variation to tolerate line fluctuation. A DIN EN 175301-803 K4 connector streamlines wiring in control cabinets, while the enclosure achieves IP65 to resist dust and low-pressure water during field service. The 30 W nominal power rating limits heat generation, enabling continuous energization at a 100 % duty cycle without exceeding temperature thresholds. A concealed manual override identified by code N9 lets technicians shift the spool mechanically during commissioning or power loss without exposing moving parts.
Hydraulic performance centers on a maximum operating pressure of 350 bar in ports P, A, and B, allowing the valve to direct flow in high-pressure supply lines; port T is limited to 210 bar to protect return plumbing. The design passes up to 80 L/min when operated on direct current, providing adequate flow for medium-sized actuators. A B10 throttle insert with a 1.0 mm orifice sits in port P to damp inlet surges and improve metering accuracy at low spool overlaps. Thermal limits are defined by a 120 °C maximum coil surface temperature to preserve insulation and by a hydraulic fluid range from −20 °C to +80 °C so seals remain compliant in cold starts and sustained operation. Together these parameters ensure reliable switching under varied ambient and fluid conditions.
