MOOG G771K289A Servo Valve
The MOOG G771K289A Servo Valve is part of the MOOG G771 Series of high-performance electrohydraulic servo valves. It is designed for demanding hydraulic control applications where precise and dynamic flow control is required.
For customers searching for the legacy MOOG G771K200A or MOOG G771K240A, the G771K289A can be used as the replacement reference for these models.
Replacement reference:
G771K200A → G771K289A
G771K240A → G771K289A
Because servo valve configurations may vary, the complete model number, nameplate information and application requirements should be checked before ordering.
