Product Overview
The Rexroth 4WE10JA50/EG24N9K4/M (Material Number R901278782) is a high-performance direct-operated solenoid directional control valve from the renowned Rexroth 4WE10 series. Engineered for precise control of start, stop, and direction of hydraulic fluid flow, this 4-way, 3-position valve features a J-type spool configuration and is actuated by a wet-pin AC/DC solenoid with a nominal voltage of 24V DC. The “N9” designation indicates the presence of a concealed manual override, while the “K4” suffix denotes an ISO 4401-05 (NG10 / CETOP 5) standard mounting interface with a spring return and detent mechanism. This valve is a critical component in industrial hydraulic systems requiring reliable, repeatable directional control of actuators, cylinders, and motors.
