The 4WE6D6X/EG24NK4QMBG24 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and serves to switch hydraulic flow paths in automated machinery. It operates on a nominal voltage of 24 V DC, and its coil draws a rated current of 1.25 A while consuming 30 W of nominal power. A voltage tolerance of ±10 % keeps the solenoid functional during supply variations, and a 100 % ED duty cycle allows continuous energizing without thermal cycling. Electrical hookup is provided by a K4 connector in accordance with EN 175301-803, and the enclosure meets IP65 to block dust and low-pressure water jets. The unit is supplied without a manual override, preventing accidental spool movement during service.
Integration is simplified by an NFPA D03 mounting interface and an ISO 4401-03-02-0-05 porting pattern, ensuring compatibility with standard subplates. Spool position is reported by a QM-B sensor designed for 24 V DC so control systems can confirm valve status. The hydraulic section carries up to 80 l/min of flow, with A, B, and P ports rated for 350 bar and the tank port rated for 210 bar. System oil must meet ISO 4406 cleanliness class 20/18/15 to protect the spool and bore from contamination.
