Product Overview
The Rexroth 4WRA6V30-23/G24N9K4/V-589 (Material Number R900953854) is a direct-operated, proportional directional valve from the proven 4WRA series, engineered by Bosch Rexroth for precise, infinitely variable control of flow direction and magnitude in industrial hydraulic systems. Utilizing a proportional solenoid acting directly on the valve spool, this NG6 (CETOP 3 / ISO 4401-03) size valve delivers smooth, stepless directional control proportional to the electrical command signal, making it ideal for applications requiring accurate velocity and position regulation rather than simple on/off switching. The “V” suffix denotes FKM (Viton) seal compatibility for use with phosphate ester (HFD) and other aggressive hydraulic fluids, while the G24 designates a 24 VDC high-performance proportional solenoid. As a genuine Rexroth proportional valve, it provides the dynamic response, hysteresis performance, and long-term repeatability demanded by modern closed-loop and open-loop industrial control architectures.
