The 4WE6J73-6X/EG24N9K4/A12B08 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks where compact subplate mounting is required. It fits the ISO 4401-03-02-0-05 (NFPA D03) pattern so the body can be installed on common manifolds without adapters. The valve tolerates 350 bar on the pressure and work ports, while the tank port is limited to 210 bar to protect return lines. A maximum flow of 80 l/min lets the unit drive cylinders or motors in medium-flow circuits. The solenoid is energized with 24 V DC, draws 1.25 A, and consumes 30 W, delivering steady magnetic force across the rated stroke. Continuous energization is possible because the coil is specified for a 100 percent duty cycle, enabling repeatable switching in automated cycles.
Environmental and electrical characteristics complete the profile. An IP65 housing resists dust ingress and low-pressure water jets, allowing installation on exposed machinery. Wiring is completed through a DIN EN 175301-803 three-pin connector, which standardizes plug selection across multiple valves. The coil winding meets insulation class F so it tolerates elevated temperatures during extended service. A concealed manual override lets maintenance staff shift the spool without tools while preventing accidental activation. Surface temperature of the coil can reach 120 °C under load, and an internal suppressor limits switch-off overvoltage to 500 V to protect control relays. Switching time increase is enabled to smooth the transition between spool positions, and a 0.8 mm pressure-port throttle insert moderates inrush flow for gentle actuator starts.
