The 4WE6E6X/EG24K4QRABG24E directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressurized fluid to actuators in automated hydraulic machinery. The valve is built to nominal size 6, allowing a compact envelope suitable for D03 manifolds. A duty cycle of 100 % ED permits the coils to remain energized continuously without thermal derating. Maximum flow reaches 80 l/min so the unit can drive medium-sized cylinders at working speed. Ports P, A, and B withstand 350 bar, enabling integration into high-pressure circuits. The electromagnetic coils run on a nominal 24 V DC supply, draw a rated current of 1.25 A, and dissipate 30 W, providing predictable electrical loading. A voltage tolerance of ±10 % maintains reliable shifting when supply levels fluctuate.
The valve offers three spool positions to alternate between forward, neutral, and reverse flow paths. Inductive position monitoring on the A and B ends supplies status signals to supervisory controllers. The tank port tolerates 210 bar, preventing damage when return line pressure rises. Coil surface temperature can reach 120 °C during continuous operation, so adjacent components must be spaced accordingly. An IP65 enclosure rating blocks dust and low-pressure water jets, permitting installation on outdoor machinery. Mounting follows the NFPA T3.5.1 R2-2002 D03 interface with an ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with standard sub-plates. Total weight with two solenoids is 1.95 kg, simplifying manual installation and routine servicing.
