Product Overview

The MOOG G761‑3002B is a classic two‑stage nozzle‑flapper mechanical‑feedback electro‑hydraulic flow‑control servo valve. It converts analog electrical command signals into continuously adjustable hydraulic flow output. It accurately realizes closed‑loop control of position, velocity, force and pressure for hydraulic actuators. With steel valve body supporting maximum working pressure up to 350 bar, it serves as the core control component of high‑pressure high‑dynamic hydraulic systems, widely deployed for heavy‑duty industrial equipment and dynamic test benches, delivering stable, repeatable high‑precision hydraulic motion control.
