Product Details

MOOG 72-1202-10 is a 72 series two-stage mechanical feedback electro-hydraulic servo valve, designed for high flow precision closed-loop hydraulic control applications. This moog servo valve adopts dry torque motor and dual-nozzle flapper pilot stage structure, delivering excellent dynamic response, low hysteresis and outstanding repeatability under long-term cyclic loading conditions. It uses mechanical spool feedback to stabilize flow output without electronic spool feedback, maintaining stable performance under industrial vibration and temperature variation. The valve is equipped with a field-replaceable first-stage filter, which effectively captures solid contaminants in hydraulic fluid and protects the precision internal components of the servo valve, reducing maintenance cycles and system downtime. It accepts analog current command signals to drive the torque motor, adjust spool opening and convert electrical signals into proportional hydraulic flow, so as to precisely control the displacement, speed and loading force of hydraulic actuators. The valve body is precision machined from high-strength alloy steel with anti-corrosion surface treatment, compatible with mineral oil and fire-resistant hydraulic fluid. This electro-hydraulic valve supports 3-way and 4-way hydraulic circuits, widely used in material fatigue test benches, aerospace structural loading test systems, automotive component durability test equipment and hydraulic simulation platforms. It can be matched with MOOG digital servo controllers to build complete multi-axis synchronous electro-hydraulic closed-loop control systems for heavy-duty industrial loading projects.
