Product Overview
The MOOG D765-606G / S04J0GAEUSA0 is a high-performance, two-stage electrohydraulic servo valve engineered by MOOG, the global benchmark in precision motion control. Operating on a nozzle-flapper pilot stage with a spool-type main stage, this valve converts low-power electrical command signals into highly accurate hydraulic flow and pressure outputs. It is designed for closed-loop position, velocity, and force control in demanding industrial and aerospace-derived motion systems where dynamic response, resolution, and long-term null stability are critical. The D765 series is a proven workhorse in applications requiring fast response times, minimal hysteresis, and precise metering of hydraulic fluid.
