The 4WE6E163-6X/EG24N9K4 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It uses nominal size 6, and its mounting interface follows ISO 4401-03-02-0-05 so it seats on standard subplates. Four main ports handle pressure, return, and work lines, while a concealed N9 manual override lets technicians shift the spool by hand; this override can vent to tank at up to 50 bar. The solenoid operates on 24 V DC, drawing 1.25 A within a ±10 % voltage band, and it consumes 30 W to limit thermal load. Wiring is completed through a K4 plug that meets DIN EN 175301-803.
The hydraulic section tolerates 350 bar on ports A, B, and P, and the tank port withstands 210 bar, allowing the unit to run in high-pressure circuits. It passes up to 80 l/min when powered by direct current, providing adequate flow for medium actuators. Continuous duty is supported because the duty cycle is 100 % (S1). An IP65 protection class shields the coil from dust and low-pressure water jets. Fluid entering the valve must meet ISO 4406 20/18/15 cleanliness to prevent spool wear and sticking. Together these parameters ensure reliable switching performance in hydraulic automation tasks.
