MOOG G771K301A Servo Valve
The MOOG G771K301A Servo Valve belongs to the MOOG G771 Series of high-performance electrohydraulic servo valves.
The MOOG 771/772/773 family uses a two-stage Mechanical Feedback (MFB) design and is intended for hydraulic control systems requiring precise flow control and high dynamic response. Moog
For customers searching for the legacy MOOG G771K625A Servo Valve, the G771K301A can be used as the replacement reference:
G771K625A → G771K301A
Before ordering, customers should confirm the complete model number, valve nameplate information and application requirements because individual servo-valve configurations may differ.
MOOG G771 Series Features
According to MOOG’s current 771/772/773 Series documentation, the series uses a two-stage mechanical-feedback design with double-nozzle pilot-stage technology. MOOG lists high dynamics, high resolution, low hysteresis and high spool driving forces among the series characteristics. Moog
Key series characteristics include:
- Two-stage electrohydraulic servo valve
- Mechanical Feedback (MFB) design
- Analog electrical interface
- Precise hydraulic flow control
- High dynamic response
- High resolution
- Low hysteresis
- High spool driving forces
- Compact and rugged construction
MOOG currently lists the G771 mounting pattern as Size 02 (ISO 10372-02-02-0-92). Exact flow, pressure and electrical specifications depend on the individual valve configuration, so those values should be confirmed from the actual nameplate or complete ordering code. Moog
