Product Introduction: Part of Moog’s G772 series, this servo valve is designed for high-performance applications requiring rapid response and precise control. It uses a 2-stage design with a dry torque motor and mechanical feedback, delivering exceptional dynamic performance in a compact form factor. The valve is built for durability, with components resistant to vibration and temperature extremes, making it suitable for aerospace and industrial applications.
Technical Specifications: The rated flow rate is 4–57 l/min (1–15 gpm) at a pressure drop of 35 bar (500 psi). The maximum operating pressure is 315 bar (4,500 psi). It accepts input signals of 8–200 mA and operates on a 24 VDC power supply. The frequency response is 150–250 Hz, with a step response time of 3–10 ms for ultra-rapid adjustments.
Functional Features: The dry torque motor eliminates the need for hydraulic fluid in the pilot stage, reducing maintenance and improving reliability. Mechanical feedback via a cantilever spring ensures stable spool positioning, with hysteresis <0.3% for precise control. The valve’s compact design allows integration into space-constrained systems, such as aircraft flight control systems. It is available in intrinsically safe versions, certified for use in hazardous environments.
Application Scenarios: Used in aircraft flight control systems to actuate ailerons and rudders, ensuring precise maneuvering. In high-speed printing presses, it controls paper tension for consistent print quality. It also regulates hydraulic actuators in automotive test rigs, simulating road conditions for vehicle durability testing.
