Product Overview
The MOOG G761-3004B / H38JOGM4VPL 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, flapper-nozzle pilot stage that hydraulically positions a precision-ground spool within the second stage, delivering infinitely variable, bidirectional flow control proportional to the electrical input current. Engineered for closed-loop position, velocity, and force control architectures, the G761 series is the industry-standard interface between high-response electronic controllers and demanding industrial hydraulic actuators, offering exceptional resolution, minimal hysteresis, and fast dynamic response in the most critical motion-control loops.
