Product Overview
The MOOG D662-4010 is a high-performance servo proportional valve from the MOOG D662 series, engineered for precise electrohydraulic control of flow direction and magnitude in demanding industrial and mobile hydraulic systems. Utilizing MOOG’s proven two-stage servo valve architecture, the D662-4010 features a torque-motor-driven pilot stage and a spool-type main stage, delivering fast dynamic response, high resolution, and excellent repeatability. This valve is designed to interface with closed-loop control systems, making it ideal for applications requiring accurate position, velocity, force, or pressure regulation. Its robust construction and precision spool-to-sleeve fit ensure minimal internal leakage and long service life in continuous-duty industrial environments.
