The 4WE6U10B6X/EG24K4QM0G24 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes pressurized fluid to actuators in hydraulic automation. The built-in 24 V DC solenoid draws 30 W of nominal power, permitting use with common machine control supplies. A 100 % duty cycle lets the coil stay energized indefinitely, while insulation class F protects the winding against heat. The coil surface can reach 120 °C, so adjacent parts must withstand that temperature. Command signals may be issued at up to 4.2 switching events per second for responsive motion control. When the coil is de-energized the driver must absorb up to 500 V of switch-off overvoltage, and during normal operation it must keep the supply within ±10 % of nominal to prevent erratic shifts.
The hydraulic stage handles flows to 80 L/min and sustains 350 bar on the pressure, A, and B ports, while the tank port is limited to 210 bar for return-line safety. Its ISO 4401-03-02-0-05 porting pattern fits standard size 06 subplates, streamlining manifold layout. NBR seals contain mineral-oil media and resist the pressures specified. System oil should be maintained at ISO 4406 cleanliness class 20/18/15 to avoid spool wear. Electrical connection is made through a DIN EN 175301-803 K4 molded plug that, when properly fastened, achieves IP65 protection against dust and water jets.
