Product Overview
The Rexroth 4SEC 6 E2X/G24N9K4 (Material No. R901509281) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4SEC series, size 6 (NG6 / CETOP 3). It is designed to control the start, stop, and direction of fluid flow in industrial hydraulic systems, functioning as the central control element for actuator movement. The valve features a robust housing, hardened and precision-ground spool, and wet-pin AC/DC solenoids with a 24 V DC coil, delivering fast, reliable switching with minimal pressure drop. The type “E” designation indicates a spring-centered, spring-return configuration, ensuring the spool returns to the neutral position when de-energized. With a nominal flow capacity of up to 60 L/min and a maximum operating pressure of 350 bar, this valve is engineered for demanding industrial duty cycles and is fully interchangeable with standard Rexroth NG6 mounting patterns.
