The 4WE6J6X/EW110NK4/B08 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and serves to route pressurized fluid to actuators in hydraulic automation circuits. Its nominal size 6 (NG6) dictates port geometry suited for compact machinery, while the ISO 4401-03-02-0-05 (NFPA D03) mounting interface lets the valve bolt directly to standard subplates without adapters. A coil designed for 110 V AC at 50/60 Hz draws 220 VA during energizing to shift the spool but settles to 50 VA holding power to limit energy use. Continuous duty is permitted because the winding is rated for a 100 % duty cycle, an H-class insulation system, and a permitted surface temperature of 120 °C. Electrical connection is made through a DIN EN 175301-803 three-pole plug with a protective earth, enabling quick replacement in service bays.
The hydraulic side supports a maximum operating pressure of 350 bar at ports A, B, and P, while the tank port tolerates up to 160 bar so return lines can see elevated back-pressure without damage. A peak flow of 60 l/min establishes the throughput limit for actuators connected to the valve, and a maximum switching frequency of two cycles per second prevents heat build-up in the solenoid and spool assembly. A 0.8 mm throttle insert in port P moderates pilot flow to reduce shock during shifting. Manual override capability permits spool actuation without power during commissioning or fault recovery. The enclosure carries an IP65 ingress rating, which protects internal parts from dust and water jets encountered on mobile or wash-down equipment.
