4WE6X5A6X/EG24N9K4

The 4WE6X5A6X/EG24N9K4 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series to switch hydraulic flow paths in automated machinery. Its solenoid coil is rated for 24 V DC, enabling direct connection to common control voltages, and draws 1.25 A under nominal conditions to generate the magnetic force required for reliable shifting. Electrical consumption is limited to 30 W, which simplifies thermal calculations inside compact manifolds. A duty cycle of 100 % ED means the coil may remain energized continuously without enforced cooling pauses, while a permitted coil surface temperature of 120 °C defines the maximum operating limit before insulation degrades. Wiring is completed through a DIN EN 175301-803 (K4) plug that supports fast service exchange, and the sealed housing achieves an IP65 protection class to prevent dust ingress and water jets during wash-down.

For mechanical integration, the valve follows the NFPA T3.5.1 D03 interface so it bolts onto standardized sub-plates, and its porting pattern matches ISO 4401-03-02-0-05 to align internal passages without adapters. Hydraulic capacity includes a maximum operating pressure of 350 bar at ports P, A, and B, while the tank port tolerates up to 210 bar, allowing installation on high-pressure circuits with elevated return lines. Flow rates reach 80 l/min in direct-current service, supporting medium-sized actuators without excessive pressure drop. A concealed manual override designated N9 permits local actuation during commissioning or power loss without exposing moving parts. The assembled mass is 1.95 kg, light enough for manifold-mounted stacks yet substantial enough to resist vibration.
