Product Details

MOOG 151D426A-1 is a two-stage electro-hydraulic servo valve with mechanical feedback, designed for high-precision closed-loop hydraulic control systems. This moog servo valve adopts torque motor and dual-nozzle flapper pilot stage structure, which achieves fast dynamic response, low hysteresis and excellent repeatability during continuous cyclic operation. The mechanical spool feedback structure stabilizes flow output without electronic position feedback, ensuring stable control performance even in environments with vibration and temperature fluctuation. An internal replaceable filter is installed inside the valve body to block solid contaminants in hydraulic oil, protect precision internal components and reduce 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 used in material fatigue test benches, aerospace structural loading test systems, automotive component durability test equipment and industrial hydraulic simulation platforms. It can match MOOG motion controllers to build complete closed-loop electro-hydraulic control systems for multi-axis synchronous loading projects.
