Product Overview
The Rexroth 0811404033 is a high-response proportional directional control valve engineered by Bosch Rexroth for precise, electro-proportional control of hydraulic flow direction and magnitude in demanding industrial systems. As part of the Rexroth proportional and servo valve family, this valve utilizes a precision-machined spool and sleeve assembly actuated by a proportional solenoid, enabling infinitely variable flow control proportional to the electrical command signal. The 0811404033 serves as a critical interface between electronic control systems and hydraulic actuators, delivering smooth, repeatable motion control for positioning, velocity, and force regulation in closed-loop and open-loop circuits. Its robust construction and high-resolution metering characteristics make it a preferred solution for applications requiring fast response, low hysteresis, and excellent repeatability.
