Product Overview
The Rexroth 4WRZE 16 E1-150-74/6EG24N9EK31/F1D3M (Material No. R901062222) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series, designed for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 16 (NG16) nominal bore, this valve utilizes a two-stage design in which a proportional pilot valve actuates the main spool of the second stage, delivering infinitely variable directional and flow control proportional to the electrical command signal. The integrated position feedback of the main spool ensures exceptional repeatability, minimal hysteresis, and fast dynamic response, making it a benchmark component for closed-loop and open-loop motion control architectures.
