The 4WE6T6X/EG24N9DA/V/62SO43A-657-4 directional spool valve belongs to Bosch Rexroth’s WE Directional Spool Valves series and is intended to shift hydraulic flow paths in automated machinery. The solenoid section works on a nominal 24 V DC supply, and a voltage tolerance of ±10 percent allows it to accept common industrial power variations. Its coil draws 1.25 A at that voltage, translating to a nominal power demand of 30 W that planners can include in control panel load calculations. A 100 percent duty cycle permits continuous energizing without enforced cool-down, while insulation class F and a permitted coil surface temperature of 120 °C keep thermal stress within safe limits. A concealed N9 manual override lets technicians reposition the spool during commissioning or power loss, and the override is rated for tank pressures up to 50 bar to prevent seal damage when used under residual line pressure.
The pressure stage of the same valve withstands 350 bar on ports A, B, and P, so it suits high-pressure circuits that drive cylinders or motors directly. The return port T may be loaded to 210 bar, giving designers freedom to use counterbalance or back-pressure devices without exceeding the housing rating. Flow capability reaches 80 l/min at direct current operation, and a maximum switching frequency of 4.2 cycles per second supports rapid directional changes in servo-type loops. Installation follows the ISO 4401-03-02-0-05 mounting pattern, and the porting layout matches the NFPA T3.5.1 D03 interface, which simplifies manifold standardization across multiple valve sizes. Fluid entering the unit must meet cleanliness class ISO 4406 (c) 20/18/15 to avoid spool sticking and wear, completing the functional data required for proper integration.
