Product Overview
The Rexroth 4WE6E6X/EG24N9K4 (R900561278) is a direct-operated, solenoid-actuated directional spool valve from the globally recognized Bosch Rexroth 4WE6 series. Designed around the proven 4WE6 platform with a nominal size of NG6 (CETOP 3 / ISO 4401-03), this valve controls the start, stop, and direction of hydraulic fluid flow within industrial power units and manifold systems. The “E” spool designation provides a closed-center, three-position configuration (P, T, A, B blocked in the neutral position), making it ideal for holding actuator position and preventing drift when the solenoids are de-energized. The “6X” series index denotes the current Rexroth design generation, while the EG24N9K4 solenoid designation specifies a 24 V DC high-performance wet-pin solenoid with a nominal 30 W rating, an ISO 4400 / DIN EN 175301-803 (DIN 43650) plug connection, and a manual override. As a core component in modern hydraulic control circuits, this valve delivers fast, repeatable spool shifting and precise flow direction control for demanding industrial machinery.
