Product Overview
The Rexroth 4WRZE 16 W6-150-74/6EG24N9ETK31/A1D3M (Material Number: R900977490) is a high-performance, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. As part of the Rexroth 4WRZE series, this valve features a size 16 (NG16) nominal bore and a rated flow capacity of 150 L/min at a 10 bar pressure drop per land. It utilizes a proportional solenoid on one end and a spring return on the opposite end, enabling continuous, infinitely variable spool positioning proportional to the electrical input signal. The integrated onboard electronics (OBE) with a central electrical connector ensure optimized signal conditioning, reduced wiring complexity, and enhanced immunity to electromagnetic interference. This valve is engineered to serve as a critical control element in closed-loop and open-loop hydraulic circuits, delivering exceptional dynamic response and repeatability for high-precision motion control applications.
