Product Overview
The MOOG 072-2623 / S15FCFA4VBLN is a high-performance, two-stage electrohydraulic servo valve engineered by Moog, the global benchmark in precision motion control. This valve operates on a torque-motor, flapper-nozzle pilot stage that hydraulically actuates a precision-ground spool within the second stage, delivering infinitely variable flow control proportional to the electrical input signal. Designed for closed-loop position, velocity, and force control architectures, the S15FCFA4VBLN provides exceptional dynamic response, minimal hysteresis, and superior resolution, making it the definitive choice for demanding industrial and aerospace-grade motion control systems where accuracy and repeatability are non-negotiable.
