4WE6H6X/EG24N9DK35L

The 4WE6H6X/EG24N9DK35L directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is installed in hydraulic circuits to switch flow paths under electronic command. With a nominal size of 6, it fits compact manifolds used in machine tools and mobile equipment. The interface follows NFPA T3.5.1 D03 so it aligns with standard subplates across North American designs. A mounting pattern of ISO 4401-03-02-0-05 ensures bolt positions match common CETOP 03 ports. The valve withstands operating pressures up to 350 bar on ports A, B, and P, allowing it to handle high-pressure supply lines. Tank port T can accept up to 210 bar in direct-current service, supporting circuits with elevated back-pressure. Maximum flow of 80 l/min keeps pressure drop moderate in medium-size actuators. Hydraulic cleanliness must be kept to ISO 4406 class 20/18/15 to protect the precision spool and reduce wear. The spool can be shifted from any installation position, which simplifies layout in tight manifolds. A concealed manual override identified as N9 lets maintenance staff move the spool mechanically during commissioning or power loss.

The electromagnetic actuation runs on a 24 V DC supply, so machine control cabinets can power the coils directly from common logic-level power buses. At this voltage the coil draws a rated current of 1.25 A, delivering a nominal power consumption of 30 W for consistent magnetic force. The electrical interface is an M12×1 four-pin connector coded DK35L, giving quick plug-and-play wiring and secure strain relief. Continuous operation is possible because the duty cycle is 100 % ED, preventing thermal shutdown during long holding periods. An enclosure rating of IP65 shields the solenoid and connector against dust and low-pressure water jets, enabling use on outdoor equipment. The valve body weighs 1.95 kg with two solenoids fitted, light enough for direct manifold mounting without extra support. These electrical and mechanical characteristics complete the valve’s profile and show how it maintains reliable switching in automated hydraulic systems.
