Product Overview
The MOOG S15FOFA4VBLH / 072-1202-10 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, double-nozzle pilot stage that hydraulically positions a precision-ground, four-way sliding spool in the second stage. The result is infinitely variable, bidirectional flow control with exceptional resolution and dynamic response. Designed for closed-loop position, velocity, and force control architectures, this servo valve serves as the critical interface between low-power electrical command signals and high-power hydraulic actuation in demanding industrial and aerospace-grade motion systems. Its robust construction and proven Moog nozzle-flapper technology deliver the fast response, low hysteresis, and long-term drift stability required for the most exacting industrial servo applications.
