MOOG G772K240A Servo Valve Overview

MOOG G772K240A is a high-performance two-stage electro-hydraulic servo valve from the G770 series, designed for precise control of hydraulic flow, pressure, position, speed, and force in demanding industrial and aerospace systems.

1) Product Summary

The G772K240A converts an analog electrical signal into a proportional hydraulic flow output, enabling extremely accurate closed-loop motion control. It is widely used in aerospace testing, power plants, metallurgy, heavy machinery, and industrial automation.

Typical roles

Flight simulators & aerospace test rigs
Steel rolling mill hydraulics
Injection molding machines
Turbine & power plant control
Automotive durability testing

2) Key Features

Servo valve architecture

2-stage design with torque-motor driven pilot stage
Dual-nozzle flapper pilot and spool-type power stage
Mechanical feedback via cantilever spring
Fail-safe spring-centered spool (returns to neutral on signal loss)

Performance highlights

High dynamic response and bandwidth
High resolution & low hysteresis
Excellent linearity and repeatability
Rugged stainless-steel construction
Field adjustable null bias
