The 4WE6X5B6X/EG24N9K4 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes pressure fluid in automated hydraulic circuits. Its size 6 body fits compact manifolds while the four available ports let it connect a pump line, a tank line, and two actuator lines. All ports comply with the ISO 4401-03-02-0-05 pattern so subplates can be exchanged without altering pipework. The solenoid is energized by 24 V DC; under this supply it draws 1.25 A and therefore dissipates 30 W, defining the load for the control power supply. Electrical hookup is made through a DIN EN 175301-803 K4 connector, and a concealed manual override marked N9 allows spool actuation when power is absent.
The valve handles up to 80 l/min of hydraulic oil in direct-current operation, supporting medium-flow machinery. Pressure capability reaches 350 bar on the pressure and service ports, with the tank port limited to 210 bar, enabling safe return flow without overstressing the housing. An IP65 rating shields the coil and terminals from dust and water jets so cabinet protection is unnecessary. Coil surface temperature may rise to 120 °C during sustained duty, a limit that guides thermal spacing inside manifolds. An internal suppression circuit restricts switch-off overvoltage to 500 V to protect driver outputs, and its calculated mean time to dangerous failure of 300 years underpins long service intervals in safety-related hydraulic automation.
