The 4WE6E73-6X/EG24N9K4/A12 CSA valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth. It is built to shift hydraulic flow paths in automated power units. The model uses a wet-pin solenoid for actuation, and the spool is arranged in a 4/3-way configuration identified by symbol E73, allowing three centered positions with four ports. Electrical control is designed around a nominal supply of 24 VDC; within a ±10 % tolerance this input draws a rated current of 1.25 A and consumes 30 W. Continuous energizing is permitted because the duty cycle is 100 % and the coil insulation is class F. The winding can reach a surface temperature of 120 °C without damage. Interface to manifolds follows porting pattern ISO 4401-03-02-0-05, enabling direct mounting on standard subplates.
For cabinet wiring the valve carries a connector that matches DIN EN 175301-803, and the enclosure is sealed to IP65 so sprayed water and dust cannot enter during machine operation. Hydraulic limits include a maximum operating pressure of 350 bar at ports P, A, and B, while port T is permitted up to 210 bar in direct current service. The flow path handles up to 80 liters per minute, which supports medium-size actuator circuits without excessive pressure drop. These ratings are fixed when the coil is powered under the voltage and temperature conditions listed earlier. Combined, the electrical and hydraulic figures define a compact directional unit that integrates easily into automated manifolds where reliable switching, rapid cycling, and secure environmental protection are required.
