Product Overview
The Rexroth 4WE 6 E62/EG24N9K4 (Material Number: R900561278) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 6 series, engineered by Bosch Rexroth for precise control of start, stop, and direction of hydraulic fluid flow in industrial power units. Featuring a three-position, four-way (4/3) spool configuration with a closed-center “E” spool type, this valve directs pressurized flow to the selected actuator port while returning the opposite port to tank, enabling bidirectional control of cylinders and motors. The integrated wet-pin AC/DC solenoid with a nominal 24 VDC coil (EG24 designation) provides fast, reliable spool shifting, while the N9 option denotes a concealed manual override for safe commissioning and emergency actuation. With a size 6 (NG6 / CETOP 3) interface, this valve is a direct-fit, drop-in replacement for OEM Rexroth installations and is widely deployed in plastic injection molding machines, metallurgical presses, machine tools, and general industrial hydraulic manifolds.
