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
