The 4WE6W6X/EG24N9K72LSO407 AN directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and functions as a flow-routing element in hydraulic automation. It is built in nominal size 6, allowing compact block installation. The subplate interface follows ISO 4401-03-02-0-05, so the unit fits standard manifolds without adaptation. Flow passages conform to the ANSI B93.9 porting pattern for consistent piping layouts. A 24 V DC coil shifts the spool while drawing a nominal 8 W, and the electromagnetic section can run continuously because the duty cycle is specified at 100 percent (S1). Coil surface temperature stability is maintained up to 85 °C, permitting use near warm reservoirs. Electrical insulation is grouped under VDE protection class III for extra-low-voltage circuits.
Wiring is completed through an M12×1 four-pin connector coded K72L, which enables quick exchange of the solenoid assembly. The housing carries an IP65 rating, giving resistance to dust and water jets during outdoor or wash-down service. A concealed N9 manual override allows direct spool actuation when power is absent. Hydraulic capacity reaches 60 l/min in direct-current operation for the SO407 version, serving medium-flow actuators. Ports A, B, and P tolerate 315 bar while the tank port withstands 210 bar back pressure without malfunction. Switching commands can be issued at up to two cycles per second, supporting rapid directional changes in servo loops.
