Product Overview
The Rexroth 4WRZE 16 W8-150-74/6EG24N9ETK31/F1D3M is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series, engineered for precise control of flow direction and magnitude in demanding industrial hydraulic systems. This valve utilizes a proportional solenoid on the pilot stage to modulate the position of a main spool, delivering infinitely variable flow control proportional to the electrical input signal. With a nominal size of NG16 and a rated flow of 150 L/min at a 10 bar pressure drop per land, it serves as a critical interface between electronic control systems and hydraulic actuators, enabling smooth acceleration, deceleration, and position holding in closed-loop and open-loop applications. The integrated on-board electronics (OBE) with the “F1D3M” configuration provide enhanced signal conditioning, diagnostic capabilities, and fieldbus-ready connectivity, making this valve a cornerstone component for advanced motion control architectures.
