The 4WE6Y6X/EG24N9DK25L directional spool valve is part of the WE Directional Spool Valves series from Bosch Rexroth. Designed to shift hydraulic flow between ports in automated machinery, it relies on a 24 V DC solenoid that draws 1.25 A during actuation. A 100 percent duty cycle lets the solenoid remain energized without cooling intervals, while the coil surface may reach 120 °C before thermal limits are met. Ingress protection is rated at IP65, so the housing resists dust and low-pressure water jets common in factory environments. Electrical wiring is handled through a DK25L five-pole connector that provides quick disconnect capability. The fluid supplying the valve must meet ISO 4406 class 20/18/15 cleanliness to protect the precision spool. Working ports p, A, and B can operate up to 350 bar, allowing the unit to control circuits that run at high system pressure.
For flow management, the valve accommodates up to 80 l/min of direct-current rated flow and returns fluid to tank lines that may reach 210 bar. A concealed N9 manual override enables mechanical shifting during commissioning or power loss, and the override is intended for tank pressures no higher than 50 bar. Installation follows the NFPA D03 mounting pattern, and the interface ports match ISO 4401-03-02-0-05 dimensions to fit standard subplates. Proper clamping force is achieved by tightening the mounting screws to 7 Nm, preventing leakage without distorting the manifold face. These geometric and hydraulic limits help the 4WE6Y6X/EG24N9DK25L maintain reliable spool movement and predictable performance in automation systems that demand steady directional control.
