The G761-3002B is a servo valve manufactured by MOOG Moog. This servo valve has the characteristics of high control precision, fast dynamic response and long life, so it is widely used in aviation, aerospace, shipbuilding, metallurgy, chemical industry and other industries.
From the technical characteristics, the G761-3002B servo valve does not require a pilot oil source, and the pressure does not affect its dynamic performance, with low hysteresis, high resolution and other characteristics. At the same time, the valve also has an electrical zero adjustment function, and uses a thousand torque motor with a two-stage hydraulic amplifier, and the pre-stage is a double nozzle baffle valve. The driving force of the valve core is large, and it has been fully adjusted when leaving the factory. The pilot valve can also be replaced with the dish oil filter on site.
In terms of working principle, the G761-3002B servo valve mainly receives the corresponding modulated flow and pressure through the analog electrical signal, and is the core component of the servo control system. Its structure is mainly composed of permanent magnet torque motor, nozzle, stop plate, valve core, valve sleeve and control chamber. When there is an electrical signal input, the armature will drive the baffle to rotate, and when the baffle is close to the nozzle, the oil discharge area and flow rate of the nozzle will be reduced, thus increasing the oil pressure in front of the nozzle. Otherwise, the oil pressure in front of the nozzle is reduced. In this way, the original electrical signal is converted into a torque signal, which in turn generates a mechanical displacement signal, and finally into an oil pressure signal.
The main application areas of the G761-3002B servo valve are very wide, especially in industrial control systems requiring high precision and fast response. This servo valve is widely used in the following fields because of its high control accuracy, fast dynamic response and long life.
