Product Overview
The MOOG 3761-001 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 robust spool-type output stage, this valve delivers infinitely variable, bidirectional flow control proportional to a low-power electrical input signal. As a critical control element in closed-loop hydraulic systems, the 3761-001 provides exceptional dynamic response, high resolution, and minimal hysteresis, making it the definitive choice for applications demanding micron-level positioning accuracy, precise velocity regulation, and superior force control in demanding industrial and aerospace-grade motion control architectures.
