Product Overview
The Rexroth 4WE 10 J50/EG24N9K4/M (Material Number R901278744) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series. Designed for controlling the start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a 4-way, 3-position (4/3) spool configuration with a “J” type center condition. The valve is actuated by a high-performance wet-pin AC/DC solenoid (EG24N9K4) rated for 24 V DC, with a concealed manual override and a spring-centered return mechanism. The “N9” designation indicates a standard nitrile (NBR) seal package suitable for mineral oil-based hydraulic fluids. With a nominal size of NG10 (Cetop 5 / ISO 4401-05), this valve delivers reliable, high-flow directional control for demanding industrial applications where precise spool positioning and rapid response are critical.
