The 4WE6J73-6X/EG24N9K72L/A12 AN directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and shifts hydraulic flow paths in automated machinery. Its size 6 body defines the mounting envelope for subplate installation, while four main ports provide separate connections for pressure supply, tank return, and two actuator lines. A manifold drilled to ANSI B93.9 aligns with the port pattern so the valve seats flush without adapters. Ports a, b, and p can operate up to 350 bar, and the t line is limited to 210 bar, making the unit suitable for high-pressure circuits that still protect the return path. The spool passages accommodate a continuous flow of 80 l/min to prevent excessive pressure drop. Solenoid excitation is supplied at 24 V DC, and the coil may remain energized continuously since the duty cycle is rated at 100 %.
The electrical load draws 1.25 A at the nominal supply, translating to a coil power consumption of 30 W that must be considered in cabinet sizing. A concealed manual override identified by code N9 permits emergency shifting without pressurizing the solenoid plunger, yet remains recessed to prevent accidental actuation. Wiring is completed through an M12×1 four-pin DESINA connector, enabling quick exchange of field units and standardized color coding. The armature assembly is capable of 4.2 switching actions per second, supporting cyclic positioning tasks that do not exceed its response limit. During extended operation the external coil surface may reach 120 °C, so surrounding components must be selected for that temperature range. With a mass of 1.95 kg the valve imposes minimal load on the mounting plate and can be handled easily during assembly or service.
