Product Introduction: It is a hydraulic servo valve with excellent performance launched by Moog. It uses advanced nozzle-flapper pilot stage technology and hydraulic amplification mechanism to convert electrical signals into precise hydraulic flow output. The valve has the characteristics of compact structure, fast response, and high reliability, and can meet the precise control requirements of various industrial systems.
Technical Specifications: The maximum operating pressure is 350 bar (5,000 psi); the rated flow is 5 to 100 L/min when the pressure drop across the throttling edge is 35 bar; the frequency response bandwidth can reach 150 Hz; the step response time is ≤15 ms; the resolution is ≤0.1%, and the hysteresis is ≤0.3%; the working temperature range is -40℃ to +120℃; the anti-pollution level is NAS 6 (with built-in filter); the electrical connection supports control signals such as ±10V and 4-20mA, and can be optionally equipped with an integrated or independent electronic amplifier; the installation standard complies with ISO 4401-03/05.
Functional Features: The nozzle-flapper pilot stage has high sensitivity and can quickly respond to small electrical signal changes; the hydraulic amplification mechanism can amplify the small displacement of the pilot stage into a large flow output of the main stage, ensuring the valve’s control capability; the built-in filter can effectively prevent pollutants from entering the valve core and valve sleeve matching pair, extending the service life of the valve; the temperature compensation module is built-in to ensure stable performance of the valve in a wide temperature range; it has low noise (≤55dB) and micro-vibration characteristics, which can reduce the impact on the surrounding environment and equipment.
Application Scenarios: It is used in the servo feed system of precision machine tools, such as the micro-displacement control of the workbench of coordinate boring machines and electric discharge forming machines, ensuring the processing accuracy reaches 0.001mm; it is applied in the aerospace test field, such as the air flow adjustment of small wind tunnel test equipment and the load simulation of aircraft component fatigue test benches; it is also used in the control system of medical equipment, such as the rotation table drive of CT machines and the gradient magnetic field hydraulic control of nuclear magnetic resonance equipment.
