Product Overview
The MOOG 760A185A 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 second-stage spool, this valve delivers infinitely variable, bidirectional flow control proportional to a low-power electrical input signal. Its closed-loop architecture provides exceptional resolution, minimal hysteresis, and fast dynamic response, making it the definitive control element for high-bandwidth position, velocity, and force regulation in critical industrial and aerospace-grade hydraulic systems. The 760A185A is a direct-fit replacement for OEM Moog servo valve installations, ensuring drop-in dimensional and functional compatibility without recalibration of the host control loop.
