Product Overview
The Rexroth 4WE 6 Y70/HG24N9K4 (Material Number: R901089243) is a high-performance direct-operated solenoid directional spool valve from the proven 4WE 6 series. Engineered by Bosch Rexroth, this valve is designed to control the start, stop, and direction of fluid flow in industrial hydraulic systems. The “Y70” designation indicates a specific spool type (Y-type, tandem center) and a nominal flow rating, while the “HG24N9K4” suffix defines the solenoid actuation (24V DC high-power solenoid), manual override, and electrical connection details. This valve is a critical component for precise motion control in demanding B2B applications, offering reliable switching and long service life.
