Product Overview
The Rexroth 4WRTE25W6-350L-46/6EG24ETK31/A1M (Material Number: R900954298) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 25 (NG25) nominal bore, this valve utilizes a four-way, three-position (4/3) spool configuration with a W6 spool type, providing progressive flow characteristics for smooth acceleration and deceleration of actuators. The integrated 46-series pilot stage and 6EG24ETK31 pilot valve with 24 VDC solenoid actuation enable fast, accurate response to electrical command signals. With a nominal flow capacity of 350 L/min at a 10 bar pressure drop per land, this valve is engineered for high-pressure, high-flow applications requiring superior dynamic performance and repeatable positioning accuracy.
