Product Details

MOOG 072-702 is a two-stage mechanical feedback electro-hydraulic servo valve belonging to MOOG 72 series. It adopts dry torque motor and dual-nozzle flapper pilot stage structure, delivering excellent dynamic response, ultra-low hysteresis and high resolution for precision hydraulic closed-loop control systems. This moog servo valve uses mechanical spool feedback design to maintain stable flow output without electronic position feedback. A replaceable first-stage filter is integrated inside the valve body, which can intercept solid contaminants in hydraulic oil, simplify field maintenance and reduce equipment downtime caused by oil pollution. It accepts standard analog current control signal, continuously adjusting the spool opening and converting electrical command signals into proportional hydraulic flow output to accurately control displacement, speed and force of hydraulic actuators. The valve body is manufactured with high-strength alloy material and anti-corrosion surface treatment, compatible with mineral oil and phosphate ester hydraulic fluids, and can operate reliably under long cyclic working conditions. This electro-hydraulic valve is widely deployed in material fatigue test benches, flight simulation platforms, aerospace structural loading test systems, automotive component durability test equipment and heavy-duty industrial hydraulic machinery. It can work with MOOG motion controllers to build complete closed-loop electro-hydraulic control systems for multi-axis synchronous loading and motion control projects.
