MOOG G771K305A Servo Valve
The MOOG G771K305A Servo Valve is part of the MOOG G771 Series of high-performance electrohydraulic servo valves. The G771 Series uses a two-stage Mechanical Feedback (MFB) design and is intended for demanding applications requiring precise and dynamic hydraulic flow control. Moog
For customers searching for the legacy MOOG G771K624A Servo Valve, G771K305A can be used as the replacement reference:
G771K624A → G771K305A
Before ordering, the complete model number, valve nameplate and hydraulic/electrical configuration should be checked to confirm compatibility with the existing application.
MOOG G771 Series Features
MOOG describes the 771/772/773 family as high-performance two-stage servo valves. The design uses mechanical feedback and a double-nozzle pilot stage to provide high dynamics, high resolution and low hysteresis. Moog
Key series characteristics include:
- Two-stage electrohydraulic flow control
- Mechanical Feedback (MFB) design
- High dynamic response
- High resolution and low hysteresis
- High spool driving forces
- Compact and rugged construction
- Designed for precision hydraulic control
MOOG lists G771 as Size 02 (ISO 10372-02-02-0-92). Specifications such as flow, pressure and electrical signal depend on the individual configuration, so they should not be assumed from the abbreviated G771K305A number alone. Moog
