Product Overview
The Rexroth R900727801 (4WE6D6X/EG24N9K4) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE6 series, engineered by Bosch Rexroth for precise control of start, stop, and direction of hydraulic fluid flow in industrial power units. Featuring a “D” type spool configuration within a 6X (series 60) housing, this valve provides a closed-center, four-way, three-position function that directs pressurized flow to the selected actuator port while returning the opposite port to tank. The EG24N9K4 designation indicates a 24 V DC wet-pin solenoid with a nominal 30 W coil, an ISO 4401-03 (CETOP 3 / NFPA D03) mounting pattern, and a manual override (N9) for emergency actuation. With a maximum operating pressure of 350 bar on P, A, and B ports and 210 bar on T, the R900727801 delivers fast, repeatable spool shifting and low-pressure drop, making it a benchmark component for demanding industrial hydraulic circuits.
