The 4WE6J73-6X/EG24N9K4/A12SO43A-1755 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It routes hydraulic flow to actuators in automation circuits. With a nominal size of 6, the valve fits compact manifolds while maintaining the porting pattern ISO 4401-03-02-0-05 for standardized mounting. The pressure at ports P, A, and B can be controlled up to 350 bar, allowing use in high-pressure lines. Electrical actuation is based on a 24 V DC coil that accepts a ±10 % voltage window so supply variations do not affect switching reliability. During energization, the coil draws 1.25 A and consumes 30 W, providing the magnetic force required for spool travel. Continuous service is supported by a 100 % duty cycle (S1), enabling the solenoid to remain powered without thermal rest periods. The valve can change state up to 4.2 times per second, matching the response needs of fast cycling hydraulic machinery.
Maximum flow in direct current operation reaches 80 l/min, so the component handles moderate circuit volumes without excessive pressure drop. Tank port pressure is limited to 210 bar, protecting return lines from overload. A clamping length of 42 mm assists in securing the solenoid tube within modular stack systems. The DIN EN 175301-803 connector simplifies wiring and supports the IP65 housing, which blocks dust ingress and water jets commonly encountered near machines. A concealed manual override lets technicians shift the spool during commissioning or power loss without exposing moving parts. Switch-off overvoltage is capped at 500 V, reducing stress on the coil insulation and associated electronics.
