Product Overview
The Rexroth 4WE6D6X/EG24K4QMBG24 (Material No. R900574632) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE6 series, designed for precise control of start, stop, and direction of hydraulic fluid flow in industrial power units. Featuring a “D” type spool configuration (three-position, four-way, closed-center), this valve delivers reliable directional control with a nominal size of NG6 (CETOP 3 / ISO 4401-03). The EG24 designation indicates a 24 V DC high-performance wet-pin solenoid with integrated manual override, while the K4QMBG24 suffix denotes the specific electrical connector and solenoid variant. Engineered for high cycle rates and long service life, this valve is a direct-fit replacement for OEM Rexroth installations and is widely deployed in demanding industrial hydraulic circuits requiring accurate, repeatable spool positioning.
