Product Overview
The Rexroth 4WE 10 L50/HG24N9K4/M (Material Number: R901391161) is a high-performance solenoid-operated directional spool valve from the renowned 4WE series, designed for precise control of start, stop, and direction of hydraulic fluid flow in industrial hydraulic systems. This direct-acting, spring-centered directional control valve features a robust spool design within a 10-size (NG10 / CETOP 5) housing, delivering reliable switching performance under demanding operating conditions. The “L50” spool type provides a specific flow path configuration optimized for applications requiring a closed-center or tandem operation, while the “HG24N9K4” solenoid designation indicates a high-power wet-pin AC/DC solenoid with a nominal voltage of 24V DC, complete with an integrated manual override and a concealed manual actuator. The “/M” suffix denotes a specific design variant with enhanced sealing and mounting characteristics. As a critical component in modern hydraulic circuits, this valve ensures precise directional control, rapid response times, and long service life, making it an ideal choice for complex industrial machinery requiring dependable fluid power management.
