Product Details:

MOOG D072-017 two-stage servo valve is a high-performance flow regulator built for precision closed-loop hydraulic control systems. This servo valve adopts double nozzle-flapper pilot stage and mechanical spool feedback structure, powered by dry torque motor. The torque motor converts analog electrical command signals into flapper deflection, changing the pressure difference on both sides of the main spool to adjust hydraulic oil flow rate and direction. It precisely governs the position, speed and force of hydraulic actuators. The main spool and sleeve assembly is manufactured with ultra-precision machining, delivering low hysteresis, high linearity and excellent resolution. The mechanical feedback design ensures stable flow output and high dynamic response for precision hydraulic control.

This high dynamic flow component maintains stable working performance under high operating pressure, continuous mechanical vibration and fluctuating ambient temperature. It responds rapidly to input control signals and keeps minimal control deviation, suitable for material testing, metal forming and aerospace hydraulic simulation equipment. MOOG D072-017 two-stage servo valve is widely used in static and dynamic material fatigue testing machines, aerospace hydraulic simulation test benches, heavy metal forming presses, metallurgical rolling production lines and automated hydraulic manufacturing machinery.

The nozzle-flapper pilot stage is sensitive to hydraulic fluid contamination. Regular hydraulic oil inspection and filter replacement are essential. Fine solid particles suspended in hydraulic fluid will scratch the precision matching surfaces of spool and nozzle, leading to internal leakage and control drift. Every MOOG D072-017 flow regulator undergoes complete factory performance tests before shipment, including flow characteristic curve test, frequency response test and internal leakage inspection. Strict quality control ensures stable and repeatable precision for closed-loop hydraulic control applications.
