The 4WE6J6X/EW110N9DK25L/N12/62 CSA directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and shifts hydraulic flow paths in automation circuits where precise on-off control is required. It follows the ISO 4401-03-02-0-05 porting pattern to align with common subplate layouts, and its 350 bar maximum operating pressure on ports P, A, and B permits use in high-pressure systems. The tank port can withstand 160 bar so return lines remain stable during transient loads. Nominal flow capacity is 60 l/min, allowing medium-sized actuators to cycle without restriction, while a 1.2 mm throttle insert in the A and B lines moderates flow to reduce shock when the spool shifts. Acceptable fluid viscosity ranges from 2.8 to 500 mm²/s, giving flexibility in oil selection, and the permitted fluid temperature of −20 to +80 °C maintains seal integrity in both cold starts and sustained running. Meeting cleanliness class 20/18/15 under ISO 4406 limits particle contamination to safeguard the spool and lands.
The wet-armature solenoid is energized by a 110 V AC supply at either 50 or 60 Hz, simplifying installation where this control voltage is standard; it draws 0.52 A on 50 Hz and 0.39 A on 60 Hz, values that help size control transformers and wiring. Electrical connection is made through a DK25L five-pole Mini-Change plug, enabling quick exchange of coils in the field, and an IP65 rating protects the enclosure against dust and water jets, supporting mounting on exposed machinery. A concealed manual override identified as N9 lets maintenance staff shift the spool without electrical power during setup or fault recovery. The body provides a 42 mm clamping length to secure the valve between sandwich plates with consistent loading, and a locating hole fitted with a locking pin ISO 8752-3×8-St aligns the body on the subplate to prevent rotation.
