The 4WE6R6X/EG24N9DL directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is applied to shift flow paths in hydraulic automation systems. With a nominal size of 6, it fits compact manifolds while still handling a maximum flow of 80 l/min to support medium-duty actuator circuits. The valve mounts to subplates that follow porting pattern ISO 4401-03-02-0-05, so interchange with other size-6 components is straightforward. System pressure at ports P, A, and B can reach 350 bar, whereas the tank port tolerates up to 210 bar when direct current actuation is used. An ingress protection rating of IP65 allows installation in industrial areas exposed to dust and low-pressure water jets. Oil entering the valve must comply with cleanliness class ISO 4406 20/18/15 to prevent accelerated wear of the sliding spool.
Electromagnetic actuation is supplied at a rated voltage of 24 V DC, and the coil draws a steady rated current of 1.25 A to generate the shifting force required for reliable spool movement. The design withstands switch-off overvoltage peaks up to 500 V, protecting the insulation and connector contacts during rapid de-energization of the solenoid. A maximum coil surface temperature of 120 °C defines thermal limits for continuous cycling in closed cabinets. Electrical entry is provided by a light DL cable gland, which guides conductor sealing and strain relief in line with the IP65 housing. Operators can override the solenoid hydraulically; the concealed N9 button accepts manual pressure up to 50 bar to reposition the spool for service or troubleshooting. The assembly weighs 1.95 kg when equipped with two solenoids, supporting simple mounting without additional lifting devices.
