Product Overview
The Rexroth 4WRZE10W9-85-73/6EG24N9ETK31/F103M (Material Number R901053128) is a high-response, pilot-operated proportional directional valve from the WRZE series, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. This valve features a 4-way, 3-position spool configuration with integrated position feedback, enabling closed-loop control of spool position for exceptional repeatability and dynamic response. The model is equipped with a 24 VDC proportional solenoid, spring-centered spool return, and an amplifier interface compatible with Rexroth’s proportional control electronics. It serves as a critical control element in systems requiring smooth, infinitely variable actuation of cylinders and motors, offering a direct OEM-compatible replacement for original Rexroth components.
