Product Details

MOOG 400317100LG is a high performance two-stage mechanical feedback electro-hydraulic servo valve, designed for demanding precision closed-loop hydraulic control systems. This moog servo valve adopts torque motor and dual-nozzle flapper pilot stage structure, which delivers ultra-fast dynamic response, low hysteresis and superior repeatability under continuous cyclic loading operations. It uses mechanical spool feedback to maintain stable flow output without electronic position feedback, ensuring reliable operation in industrial environments with vibration and temperature variation. A built-in replaceable filter traps solid contaminants in hydraulic fluid, protecting the precision internal components of the servo valve and lowering routine maintenance frequency. It accepts standard analog current control signal, continuously adjusting the spool opening and converting electrical command signals into proportional hydraulic flow output to precisely control displacement, speed and force of hydraulic actuators. The valve body is manufactured from high-strength alloy steel with anti-corrosion surface treatment, compatible with mineral oil and fire-resistant hydraulic fluid. This electro-hydraulic valve is widely applied in material fatigue test benches, aerospace structural loading test systems, automotive component durability test equipment and hydraulic simulation platforms. It can be paired with MOOG motion controllers to construct complete closed-loop electro-hydraulic control systems for multi-axis synchronous loading projects.
