Product Overview

The MOOG D634-319C / R40KO2MONSP2 is a high-performance servo proportional valve from the MOOG D634 series, engineered for precise electrohydraulic control of flow and pressure in demanding industrial and mobile applications. Utilizing a robust spool-and-sleeve design with integrated position feedback, this valve delivers exceptional dynamic response, high resolution, and superior repeatability. The D634 series is a direct-operated, two-stage servo proportional valve that converts electrical input signals into proportional hydraulic output, making it an ideal choice for closed-loop motion control systems requiring accurate velocity, position, or force regulation. With its rugged construction and field-proven MOOG reliability, the D634-319C / R40KO2MONSP2 ensures stable operation even under the most severe industrial conditions.
