Product Overview
The Rexroth 4WRZE 16 W8-150-74/6EG24N9ETK31/F1V (Material Number: R900706549) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. As part of the Rexroth 4WRZE series, this valve features a size 16 (NG16) nominal bore with a four-way, three-position (4/3) spool configuration. The “W8” spool type provides a specific flow characteristic optimized for smooth, progressive metering. Actuation is achieved via a high-performance proportional solenoid with integrated position feedback (LVDT), ensuring exceptional repeatability and hysteresis performance. The valve operates on a 24 VDC supply (EG24) and includes an integrated amplifier (N9) with enable function, making it a self-contained, ready-to-install solution for closed-loop control of position, velocity, and force in hydraulic actuators. This valve is engineered for applications requiring high dynamic response, low-pressure drop, and precise flow control, such as in injection molding machines, metallurgical equipment, and advanced test rigs.
