Product Overview

The Rexroth R901382312 is a high-performance proportional directional valve engineered by Bosch Rexroth for precise, continuous control of hydraulic flow direction and magnitude in industrial systems. As part of the Rexroth proportional and servo valve family, this component utilizes a solenoid-actuated spool design that proportionally modulates flow in response to an analog electrical command signal, enabling smooth, infinitely variable control of actuator speed and direction. The R901382312 is designed for demanding closed-loop and open-loop applications where accurate velocity profiling, controlled acceleration, and repeatable positioning are critical to overall system performance. Its robust construction and precision spool-to-bore fit ensure minimal internal leakage, excellent hysteresis characteristics, and long service life in continuous industrial duty cycles.
