4WE6U6X/EG24N9K4/ZV

The 4WE6U6X/EG24N9K4/ZV directional spool valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation circuits. It attaches to subplates that follow the ISO 4401-03-02-0-05 porting pattern, allowing direct replacement within standardized manifolds. During service it conveys up to 80 l/min of oil in direct-current operation, giving medium flow capacity to actuators. Supply ports P, A, and B tolerate pressures as high as 350 bar so the valve can work in high-pressure systems. The return path through port T must stay below 210 bar in DC use to preserve seal integrity. An electromagnetic coil rated at 24 V DC draws 1.25 A when energized, providing the force needed to shift the spool. Electrical loading stays modest because the coil consumes 30 W, easing the design of power distribution panels.

Continuous operation is possible because the valve is specified for a 100 % duty cycle, meaning it can remain energized without scheduled cooling intervals. The coil surface may reach 120 °C while maintaining function, so cabinet airflow only has to remove additional heat produced by the system. Acceptable supply variation of ±10 % prevents nuisance tripping when bus voltage drifts. The actuator can reverse flow up to 4.2 times per second in DC service, supporting rapid cylinder or motor direction changes. Together the thermal margin and continuous rating protect the winding insulation during extended duty, complementing the hydraulic limits introduced earlier.
