MOOG G771K291A Servo Valve
The MOOG G771K291A Servo Valve is part of the MOOG G771 Series of high-performance flow control servo valves. It is designed for electrohydraulic control applications where precise, fast and reliable control is required.
For customers maintaining systems using the legacy MOOG G771K203A, the G771K291A can be used as the replacement reference when identifying an updated model. Because individual servo valve configurations can vary, the complete model number and application requirements should be confirmed before replacement.
G771K291A Product Features
The MOOG G771 Series uses a two-stage mechanical feedback (MFB) design. According to MOOG, the 77X family combines a low-friction double-nozzle pilot stage with mechanical feedback and is designed to provide high dynamics, high resolution and low hysteresis. Moog
Key characteristics of the series include:
- High-performance two-stage servo valve design
- Mechanical Feedback (MFB) technology
- High dynamic response
- High resolution and low hysteresis
- Compact and rugged construction
- Designed for demanding electrohydraulic control applications
