Product Overview
The Rexroth 4WRZE10E50-73/6EG24N9ETK31/F1D3V (Material Number R900945726) is a pilot-operated, two-stage proportional directional valve from the Bosch Rexroth WRZE series, designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. The valve utilizes a proportional solenoid on the pilot stage to position the main spool of the second stage, delivering infinitely variable directional and flow control proportional to the electrical input signal. With a nominal size of NG10 (size 10) and a rated flow capacity of 50 L/min at a 73 bar pressure differential per land, this valve is engineered for high-resolution metering in demanding closed-loop and open-loop applications. The integrated on-board electronics (OBE) with the “F1D3V” configuration provide factory-calibrated, closed-loop spool position control, ensuring excellent repeatability, minimal hysteresis, and fast dynamic response without the need for external amplifier cards.
