Product Introduction
On machines that demand tight position, velocity or force loops, the Moog G771K226A sits as the interface between the electronic command and the hydraulic actuator. It is a classic 2-stage nozzle-flapper design with mechanical feedback, delivering the high dynamic response and low hysteresis that the 771 series is known for.
Maintenance and controls engineers reach for this unit when an existing G771 or equivalent 77X series valve fails and the manifold pattern, pressure rating and coil configuration match; the dry torque motor and rugged construction keep it serviceable in continuous industrial duty provided fluid cleanliness is maintained.
