The 4WE6M6X/EG24N9K72L/62SO407 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow between pump, actuator, and tank in automated machinery. It mounts on subplates that follow the ISO 4401-03-02-0-05 porting pattern. The solenoid runs on 24 V DC with a ±10 % voltage tolerance and draws 8 W at nominal load, supporting energy-efficient control circuits. A continuous 100 % duty cycle (S1) lets the coil remain energized without forced cooldown. Wiring is handled through an M12×1 four-pole connector marked K72L, and the same interface limits commanded shifts to 1 Hz to protect the coil. A concealed manual override labeled N9 permits local actuation during setup or power loss.
The housing is sealed to IP65 so it resists dust and low-pressure water spray in typical plant environments. A locating hole fitted with a 3 × 8 mm ISO 8752 spring pin locks the body onto the manifold and prevents movement under vibration. Working pressure reaches 315 bar on the P, A, and B ports, while the tank port can handle 210 bar, covering most high-pressure mobile and industrial circuits. The spool passes up to 60 l/min without excessive pressure drop, and the coil surface temperature is limited to 85 °C in the So407 variant to preserve insulation life. Despite these ratings, the assembly weighs only 1.95 kg, enabling single-person installation.
