4WE6D6X/EG24N9K72L/B10SO407 AN

The 4WE6D6X/EG24N9K72L/B10SO407 AN directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automation circuits that require rapid, electrically controlled changes in flow paths. The solenoid coils are rated for a nominal voltage of 24 V DC so the valve connects easily to common machine control power supplies. Continuous duty at 100% ED allows the coil to remain energized without thermal cycling, and the nominal power draw of 8 W keeps control cabinet loading low. A maximum switching frequency of 2 cycles per second supports moderate response rates in positioning tasks, while a voltage tolerance of ±10 % ensures reliable operation despite minor supply variation. Electrical connection is through an M12x1 4-pin A-coded plug that provides quick installation and coded polarity. The concealed N9 manual override permits local actuation during commissioning without exposing the operator to moving parts. An IP65 enclosure rating blocks dust and low-pressure water jets so the valve can be mounted on equipment in typical factory environments.

Hydraulic capacities match medium-pressure circuits: ports A, B, and P withstand up to 315 bar, and the unit passes a maximum flow of 60 l/min without exceeding allowable pressure drop. Port T tolerates back-pressure up to 210 bar, which simplifies system plumbing when the return line experiences elevated pressure. A 1.0 mm throttle insert in port P moderates inrush flow to reduce shock when the spool shifts. The subplate interface follows the ANSI B93.9 pattern, allowing interchange with standardized manifolds. During de-energization, internal suppression limits switch-off overvoltage to 500 V, protecting drive electronics. Cleanliness requirements of ISO 4406 class 20/18/15 help maintain spool accuracy by preventing particulate interference. The twin-solenoid assembly weighs 1.95 kg, permitting direct mounting on compact manifolds without additional support.
