Product Overview
The MOOG 072-1203-10 is a high-performance, two-stage electrohydraulic servo valve engineered by Moog Inc., the global benchmark in precision motion control. Operating on a torque-motor, flapper-nozzle pilot stage that hydraulically actuates a spool-type second stage, this valve delivers infinitely variable, bidirectional flow control proportional to an electrical input current. Its closed-loop architecture provides exceptionally fast dynamic response, high resolution, and minimal hysteresis, making it the definitive control element for applications demanding micron-level positioning accuracy, velocity regulation, and force control within high-response industrial and aerospace-grade hydraulic systems.
