The 4WE6D6X/EG24K4QMBG24 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and serves to route hydraulic oil so automated actuators move as required. A size 6 (NG6) body keeps the unit compact for subplate mounting, while the ISO 4401-03-02-0-05 porting pattern matches common manifold layouts. The NFPA T3.5.1 D03 interface aligns the valve with American CETOP 3 footprints, supporting global interchangeability. A maximum operating pressure of 350 bar on ports A, B, and P allows use in high-pressure supply lines, and a 210 bar limit on port T protects the tank return path. Flow capacity reaches 80 l/min, giving suitable throughput for medium-duty circuits. The QMBG24 position switch monitors the “b” spool position to feed status signals to the control system, and an IP65 protection class keeps internal components sealed against dust and water spray.
A nominal coil voltage of 24 V DC provides compatibility with standard machine control power, and a ±10 % voltage tolerance lets the valve remain functional during supply variations. The coil draws a rated current of 1.25 A, establishing the electrical load placed on the power supply, while its 30 W nominal power indicates the heat generated during steady operation. Continuous service is supported by a 100 % ED duty cycle so the solenoid may stay energized without forced cooling. A maximum coil surface temperature of 120 °C defines the thermal limit that safeguards insulation from degradation. The K4 connector conforming to DIN EN 175301-803 offers a quick-disconnect plug for straightforward wiring and maintenance.
