The 4WE6J73-6X/EG12N9K4 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic flow switching in automated systems. The unit can be installed in any position and, at size 6, uses four main ports to route pressure and return lines. Its mounting interface matches ISO 4401-03-02-0-05 and the NFPA D03 pattern for straightforward manifold mounting. Direct-current operation allows a maximum flow of 80 l/min while sustaining 350 bar on ports P, A, and B; tank port pressure is limited to 210 bar under the same duty. A concealed N9 manual override permits mechanical shifting when electrical power is unavailable.
Electrically, the valve runs on a nominal 12 V DC supply and each coil draws 2.5 A. The K4 connector to DIN EN 175301-803 provides the interface and, when properly sealed, delivers IP65 protection against dust and water jets. Coil surface temperature can reach 120 °C during continuous duty, so wiring and insulation must be selected accordingly. Two solenoids bring the valve weight to 1.95 kg, which simplifies handling and panel support. These electrical and environmental characteristics complete the functional profile introduced above.
