The 4WE6W73-6X/EG24N9K4/A12 directional valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow between actuator ports, enabling automated motion sequences in machinery. The valve is built in size 6 and follows the ISO 4401-03-02-0-05 mounting pattern, so it fits standard subplates in compact manifolds. It withstands a maximum operating pressure of 350 bar on ports a, b, and p, while the tank port t is permitted up to 210 bar. During direct-current operation it passes up to 80 l/min without exceeding rated pressure loss. The solenoid assembly is designed for a nominal supply of 24 V DC and accepts a ±10 % voltage deviation without functional error. At that voltage the coil draws 1.25 A and consumes 30 W, allowing continuous control because the duty cycle is 100 % ED. An enclosure rating of IP65 protects the electrical section from dust and low-pressure water jets.
The electrical interface uses the K4 plug conforming to DIN EN 175301-803, simplifying connection to cabinet wiring. A concealed N9 manual override permits local shifting of the spool for service when power is absent. The solenoid can cycle up to 4.2 switching operations per second, supporting rapid directional commands in proportional circuits. Thermal limits are defined by a maximum coil surface temperature of 120 °C, so the unit maintains insulation integrity at elevated ambient or fluid temperatures. Even with both solenoids installed the assembly weighs 1.95 kg, which eases handling during manifold installation. The valve achieves the stated switching performance while operating within the flow and pressure limits, providing reliable high-frequency service in hydraulic automation systems where precise flow routing and compact packaging are required.
