Product Overview
The MOOG S15FOFA4VBLN / 072-1202-10 is a high-performance, two-stage electrohydraulic servo valve manufactured by MOOG, the global benchmark in precision motion control. This valve operates on a torque-motor, flapper-nozzle pilot stage that hydraulically positions 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 S15FOFA4VBLN provides exceptional dynamic response, minimal hysteresis, and long-term null stability, making it the definitive choice for critical industrial and aerospace-grade motion control systems where accuracy and repeatability are non-negotiable.

Engineering Features & Advantages
- Precision Performance: The torque-motor flapper-nozzle pilot stage delivers extremely high resolution and repeatability, with hysteresis typically below 3% and threshold below 0.5% of rated current, ensuring accurate metering of flow in the most demanding closed-loop control applications.
- High Dynamic Response: Optimized pilot stage and low-inertia spool design provide fast step response and high frequency bandwidth, enabling precise tracking of rapidly changing command signals in high-cycle industrial machinery.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original MOOG specifications for direct replacement, minimising downtime and eliminating fitment issues.
