The 4WE6D6X/EG24N9K73L directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs oil flow in hydraulic automation systems. It operates on a nominal voltage of 24 V DC and draws a rated current of 1.25 A to shift its spool. The coil absorbs 30 W of nominal power, and a 100 % duty cycle permits continuous energization without enforced cool-down intervals. Voltage may vary by ±10 %, allowing stable function on typical machine supplies. A wet-pin, detachable coil design eases replacement while keeping the winding immersed in oil for heat removal. Wiring is completed through an M12×1 four-pole connector coded K73L, which fits standardized sensor cables. The housing meets IP65 so dust and low-pressure water jets do not impair operation. During extended use the coil surface can reach 120 °C, so adjacent components must tolerate that temperature. A concealed manual override (N9) lets technicians actuate the valve mechanically during testing or power loss. Mounting follows porting pattern ISO 4401-03-02-0-05 for drop-in installation on size 03 subplates.
Hydraulic performance is defined by a maximum operating pressure of 350 bar at ports A, B, and P, enabling control of medium-pressure cylinders and motors. The tank port tolerates up to 210 bar, supporting back-pressure circuits without risking seal failure. A maximum flow of 80 l/min keeps pressure drop low in compact manifolds, while a switching frequency of 4.2 cycles per second permits rapid directional changes in automated tooling. This combination of pressure capacity, flow rate, and actuation speed allows the valve to service presses, material-handling axes, and process machinery that require fast yet dependable spool movement under continuous electrical load.
