Product Overview
The Rexroth 4WRZE 10 W8-25-73/6EG24N9EK31/F103M (Material Number: R900961299) is a high-performance, pilot-operated proportional directional valve designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. Part of the renowned Rexroth 4WRZE series, this valve features a size 10 (NG10) nominal bore and a four-way, three-position (4/3) spool configuration. It utilizes a proportional solenoid on one end and a spring return on the opposite end to modulate the main spool position, thereby delivering infinitely variable flow rates proportional to the electrical input signal. This valve is engineered to serve as a central control element in demanding applications requiring smooth acceleration, deceleration, and precise velocity control of actuators, offering exceptional dynamic response and repeatability.
