Product Overview
The Rexroth 2FRE10-44/50LBK4M (Material Number R900915815) is a high-performance, two-way proportional flow control valve engineered for precise, infinitely variable regulation of hydraulic flow in industrial drive systems. As part of the Rexroth 2FRE series, this valve utilizes a proportional solenoid that acts directly on a metering spool, allowing the flow rate to be continuously adjusted in proportion to the electrical command signal. This design provides smooth, accurate velocity control of actuators, making it an essential component for demanding motion control applications where precise flow metering and fast dynamic response are critical. The valve is a direct-operated, pressure-compensated style, ensuring stable flow independent of load pressure variations.
