Product Overview
The MOOG 072-1203-6 / S22KOFM4VBLN is a high-performance, two-stage electrohydraulic servo valve engineered by MOOG, the global benchmark in precision motion control. Operating on a mechanical force-feedback torque motor principle, this valve converts low-power electrical command signals into highly accurate hydraulic flow and pressure outputs. The S22KOFM4VBLN designation identifies a specific spool and flow configuration within MOOG’s S22 series, making it a direct-fit solution for closed-loop position, velocity, and force control systems. It serves as the critical control element in demanding industrial and aerospace-grade hydraulic circuits where dynamic response, resolution, and null stability are paramount.
