Product Overview
The Rexroth 4WE 10 LB50/EG24N9K4/M (Material No. R901324079) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series. Designed for the control of start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a robust 4-way, 3-position (4/3) spool configuration. The “LB50” designation indicates a specific spool type and spring return arrangement, while the “EG24N9K4” specifies a 24 V DC high-performance solenoid with a concealed manual override and a standard DIN EN 175301-803 (ISO 4400) connector. The “M” suffix denotes a modified or special version within the Rexroth modular system. This valve is engineered for high-pressure, high-cycle industrial applications where precise directional control and reliable shifting are critical.
