4WE6RB6X/EG24N9K4QMBG24

The 4WE6RB6X/EG24N9K4QMBG24 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for electrically actuated hydraulic circuits. It shifts flow paths with a 24 V DC solenoid coil, so it integrates with common machine control supplies, and the coil draws a rated 1.25 A, limiting panel power demand. Continuous service is permitted because the solenoid is designed for a 100 % ED duty cycle, preventing overheating during long actuation periods. The nominal electrical load is 30 W, giving predictable thermal behavior in compact manifolds. Wiring is completed through a K4 connector that follows DIN EN 175301-803, enabling quick exchange without specialized tools. When onsite intervention is required, a concealed N9 manual override lets technicians shift the spool without energizing the coil. Spool position “b” is monitored by a QM inductive switch, supplying reliable feedback to the controller and ensuring that commanded states are verified in safety-related sequences.

Hydraulic performance is defined by a maximum flow of 80 l/min, allowing the valve to regulate medium-sized actuators, while ports a, b, and p can withstand pressures up to 350 bar. The return path may see up to 210 bar at the tank port, so back-pressure-laden systems remain within specification. Mounting conforms to the ISO 4401-03-02-0-05 pattern and the NFPA D03 interface, which simplifies interchange with existing subplates. An IP65 ingress protection rating shields the coil and switch from dust and low-pressure water jets, supporting outdoor or wash-down machinery. To protect the coil driver, switch-off transients are limited to 500 V, preserving contact life in relay or transistor outputs. System cleanliness must meet ISO 4406 class 20/18/15, ensuring that spool clearances remain free of abrasive contamination. Together these limits enable stable operation across harsh duty cycles without exceeding fluid, electrical, or mechanical boundaries.
