Product Overview
The Rexroth 4WRZE 32 W8-520-73/6EG24N9EK31/F103M (Material Number: R9001007261) is a high-performance, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve features a size 32 (NG32) main stage with a 4-way, 3-position spool configuration (symbol W8), delivering a rated flow of approximately 520 L/min at a 10 bar pressure drop per land. The integrated proportional solenoid (type 6EG24N9EK31) operates on 24 VDC and includes an electrical position feedback and integrated control electronics (OBE), enabling closed-loop position control of the main spool for exceptional repeatability and dynamic response. The F103M designation indicates a specific factory-set spool overlap and tuning configuration. This valve serves as a critical interface between the hydraulic power unit and actuators in systems requiring smooth, infinitely variable directional and velocity control, such as injection molding machines, hydraulic presses, and advanced test rigs.
