Product Overview
The Rexroth 4WE 6 GA62/EG24N9K4/62 (material number R978024424) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 6 series, size NG6 (CETOP 3 / ISO 4401-03). It controls the start, stop, and direction of hydraulic fluid flow by shifting a hardened, precision-ground spool within a high-strength cast iron housing. Actuation is provided by a wet-pin AC/DC solenoid (EG24N9K4 designation: 24 V DC, high-performance solenoid with detachable coil and manual override), with spring return to the de-energized center position. The “GA62” spool type denotes a 3-position, 4-way configuration with a closed-center (all ports blocked) mid-position, making it ideal for holding actuator position and load under pressure. As a core control element in industrial power units, it serves as the pilot or main stage interface between the electrical control system and the hydraulic actuator circuit.
