Product Overview
The Rexroth 2FRE 16-43/160LBK4V (Material Number: R900747708) is a high-performance 2-way proportional flow control valve engineered for precise, electro-proportional regulation of hydraulic flow in demanding industrial systems. As part of the Rexroth 2FRE series, this valve operates on a proven spool-and-sleeve design, where an integrated proportional solenoid continuously positions the control spool in direct proportion to the applied electrical command signal. This enables infinitely variable flow metering independent of load pressure fluctuations, delivering exceptional repeatability and dynamic response. The valve serves as a critical control element in load-sensing and pressure-compensated circuits, allowing system designers to achieve accurate velocity control of actuators, smooth acceleration and deceleration profiles, and energy-efficient flow management across a wide range of heavy-duty hydraulic applications.
