Bosch Rexroth R900903906 Hydraulic Directional Valve

The Bosch Rexroth R900903906 is a 4-way directional spool valve, designated 4WE6E6X/EG12N9K4, with the catalog number R900903906. This electrically actuated directional valve redirects hydraulic oil to switch flow paths, enabling connected actuators to extend, retract, or rotate as commanded by the control electronics. Used in industrial hydraulic circuits, it supports precise, repeatable flow switching and compact packaging for space-constrained applications. For exact specifications—coil drive voltage, port sizes, maximum operating pressure, and flow characteristics—consult the official Rexroth datasheet for 4WE6E6X/EG12N9K4 (R900903906). Common applications include machine tools, automation systems, and material handling where reliable direction control of hydraulic actuators is required.
