Product Details

MOOG 072-1203-9 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, featuring fast dynamic response, ultra-low hysteresis and high resolution for high-precision hydraulic 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 built into the valve body, which can intercept solid impurities in hydraulic oil, simplify on-site maintenance and reduce equipment downtime caused by oil contamination. The rated flow reaches 225 L/min under specified pressure drop, and the maximum working pressure can reach up to 350 bar (5000 psi). It accepts ±40mA analog current control signal, which can continuously adjust spool opening and convert electrical command signals into proportional hydraulic flow output to precisely control the displacement, speed and force of hydraulic actuators. The valve body is made of high-strength alloy material with anti-corrosion surface treatment, compatible with mineral oil and phosphate ester hydraulic media, and can operate stably under long-term cyclic working conditions. This electro-hydraulic valve is widely used 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 cooperate with MOOG motion controllers to build a complete closed-loop electro-hydraulic control system for multi-axis synchronous loading and motion control projects.
