The 4WE6D6X/EG24N9K72L/B10/62SO407 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for controlling oil flow in hydraulic automation systems. It has a nominal size of 6, allowing compact installation while maintaining required flow passage dimensions. The spool symbol D establishes the flow paths used when the solenoid is energized or de-energized. A porting pattern that follows ISO 4401-03-02-0-05 lets the unit mount directly on industry subplates without adaptor blocks. The valve withstands a maximum operating pressure of 315 bar at ports a, b, and p, and a maximum tank port pressure of 210 bar so that it can operate reliably in high-pressure return circuits. Under direct current operation with solenoid option So407, the component passes up to 60 l/min, and a 1.0 mm throttle insert in port P moderates the inlet flow for smoother motion control. Positioning on the manifold is maintained by a locating hole and pin to ISO 8752-3x8-St, and a concealed manual override labeled N9 allows service technicians to shift the spool without energizing the coil.
The valve’s solenoid is designed for a nominal voltage of 24 V DC and draws a rated current of 1.25 A, which guides power supply sizing. A voltage tolerance of ±10 % lets the unit remain functional during modest supply variations, while a nominal power consumption of 8 W limits energy usage in continuous duty. Electrical connection is made through an M12×1 four-pin plug that includes a suppressor diode under the K72L designation, providing quick installation and damping of inductive kickback. The switch-off overvoltage is capped at 500 V to protect contactors and control electronics. The coil surface temperature can reach 85 °C at full load, so surrounding components must be selected accordingly for thermal compatibility. Together these electrical characteristics support reliable actuation within the specified hydraulic limits.
