4WE6D6X/EG24N9DK25L AN

The 4WE6D6X/EG24N9DK25L AN directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It shifts hydraulic flow paths in automated circuits where electrically controlled on-off functions are required. A nominal voltage of 24 V DC allows integration with standard machine control supplies, and the coil draws a rated current of 1.25 A so power demand remains predictable. Nominal power is 30 W, providing the magnetic force necessary to move the spool without excessive heat rise. Voltage tolerance of ±10 % lets the valve operate reliably despite supply fluctuations. A DK25L five-pole Mini-Change connector serves as the electrical interface for quick installation and maintenance. Continuous operation is possible because the duty cycle is 100 % ED. The unit is built in size 6, defining the cavity and flow cross-section according to Bosch Rexroth standards. An ANSI B93.9 porting pattern matches common subplates in industrial manifolds, and an IP65 enclosure rating keeps dust and low-pressure water jets from reaching internal components.

The hydraulic performance is matched to medium-pressure circuits; ports a, b, and p can be loaded up to 350 bar, while the tank port tolerates 210 bar on direct-current actuation. A maximum flow of 80 l/min allows the valve to handle moderate volume systems without cavitation. Dynamic response is supported by a switching frequency of 4.2 cycles per second, enabling precise repeatability in rapidly sequenced machinery. The coil surface may reach 120 °C under worst-case thermal conditions, so mounting clearances must account for heat dissipation. A concealed manual override identified by code N9 lets technicians shift the spool during commissioning or power loss without exposing moving parts. These capabilities combine to keep hydraulic actuators under accurate directional control in industrial automation environments.
