The 4WE6J6X/EG24N9K72L/B10 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic oil in automated systems, and its valve size 6 fits subplates that follow the ISO 4401-03-02-0-05 mounting pattern. The J spool establishes the flow positions required for typical cylinder control, while a concealed N9 manual override lets maintenance staff shift the spool without electrical power. An M12×1 four-pin K72L connector provides the interface to the solenoid; pin 4 carries the 24 V DC supply defined for the coil. The solenoid operates at a nominal 24 V DC within a ±10 % voltage window, draws 1.25 A, and dissipates 30 W, so wiring and power supplies can be sized correctly. A 100 % ED duty cycle allows the valve to remain energized continuously without overheating.


The hydraulic section is rated for demanding circuits: ports P, A, and B withstand up to 350 bar, while the tank line handles 210 bar. A maximum flow of 80 l/min sets the upper limit for actuator speed in machines that rely on this valve. A 1.0 mm throttle insert in port P meters inlet flow to smooth pressure changes during shifting. The assembly weighs 1.95 kg, which eases handling during installation or replacement. Together these pressure, flow, metering, and weight figures define the operating envelope and mechanical load the 4WE6J6X/EG24N9K72L/B10 can support in hydraulic automation.
