The 4WE6J2-6X/EG24N9K72LSO407 AN directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to automate machine actuators in mobile and industrial plants. The solenoid operates on a nominal voltage of 24 V DC and draws 1.25 A at a nominal power of 8 W, enabling energy-efficient switching. Voltage may vary within ±10 % without affecting function. Continuous operation is supported by a 100 % ED duty cycle, while the coil surface remains within 85 °C. The valve uses an M12 × 1 four-pole connector identified as K72L; pin 3 is wired to coil ground and pin 4 carries the +24 V DC supply. An IP65 enclosure rating protects the electrical interface from dust ingress and water jets.
This model follows the ANSI B93.9 porting pattern to mount on standard subplates, which reduces installation time during service work. It withstands a maximum operating pressure of 315 bar at ports P, A, and B, and a tank port pressure of 210 bar when powered with direct current. The hydraulic passages permit a maximum flow of 60 l/min under the SO407 designation so flow-induced pressure drops remain moderate. Spool actuation is limited to one switch per second, the stated maximum switching frequency, meaning the valve is intended for moderate cycling rates rather than high-frequency dithering. These capacity figures are maintained while the solenoid remains within its nominal electrical limits, ensuring reliable directional changes under continuous duty.
