Product Overview
The MOOG G761-3001B / H04J0FM4VPL is a high-performance, two-stage electrohydraulic servo valve manufactured by MOOG, the global benchmark in precision motion control. This valve operates on a torque-motor, double-nozzle, flapper pilot-stage principle that hydraulically positions a precision-ground spool within the second stage, delivering infinitely variable flow control proportional to the electrical input signal. Engineered for closed-loop position, velocity, and force control architectures, the G761 series is the industry-standard interface between electronic controllers and high-response hydraulic actuators in demanding industrial and aerospace-derived applications.
