Product Overview
The Rexroth 4WRZE25W8-325-73/6EG24N9K31/A1D3M (material number R900767522) is a pilot-operated, two-stage proportional directional valve with electrical position feedback, part of the Rexroth 4WRZE series of high-response proportional valves. The valve utilizes a high-performance proportional solenoid pilot stage to actuate the main spool of the second stage, delivering continuously variable directional and flow control proportional to the electrical command signal. With a nominal size of NG25 and a rated flow of 325 L/min at a 10 bar (145 psi) valve pressure differential, this valve is engineered for demanding industrial motion control circuits requiring precise velocity, direction, and position regulation of hydraulic actuators. The integrated position feedback of the main spool ensures high repeatability, minimal hysteresis, and excellent dynamic response, making it a direct-fit replacement for OEM Rexroth proportional valve installations.
