Product Overview
The Rexroth R901382354 is a high-response proportional directional valve from the Bosch Rexroth 4WR series, engineered to deliver precise, infinitely variable control of flow direction and magnitude in demanding industrial hydraulic systems. Utilizing a robust solenoid-actuated spool design with integrated position feedback, this valve converts an analog electrical command signal into a proportional hydraulic output, enabling smooth acceleration and deceleration of actuators without pressure spikes. As a direct-operated proportional directional valve, it serves as a critical interface between electronic control systems and hydraulic power circuits, providing exceptional metering accuracy, fast dynamic response, and repeatable performance in closed-loop and open-loop applications.
