Product Overview
The Rexroth 4WE 10 Y50/HG24N9K4/M (Material Number R901391202) 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 robust three-chamber housing with a precision-ground spool and hardened sleeve. The “Y50” spool designation indicates a specific center condition (open center, all ports connected to tank in the de-energized state), while the “HG24N9K4” solenoid configuration provides high-power wet-pin AC/DC solenoids with integrated manual override and a standard ISO 4401-05 (NG10 / CETOP 5) mounting interface. The “M” suffix denotes a modified or special version within the Rexroth modular system, ensuring exact OEM interchangeability. This valve is engineered for high cycle rates, low pressure drop, and reliable switching performance in demanding industrial environments.
