Product Overview
The Rexroth Z4WE 6 X250-31/EG24N9K4/V/60 (Material No. R901087021) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth WE series, size 6 (NG6 / CETOP 3). It controls the start, stop, and direction of hydraulic flow by shifting a precision-ground spool within the valve body via wet-pin AC/DC solenoids. Configured as a 4-way, 3-position (4/3) function with a tandem (X-type) center condition, this valve provides closed-center port blocking with pump unloading to tank in the neutral position, making it ideal for energy-efficient load holding and multi-actuator circuits. The EG24N9K4 designation denotes 24 V DC high-performance solenoids with integrated manual override and a standard DIN EN 175301-803 (ISO 4400) connector, while the /60 indicates the current component series. Engineered for high flow capacity relative to its compact size, this valve is a direct-fit replacement for OEM Rexroth installations in demanding industrial hydraulic systems.
