G772K620A China offers precision control component servo valve

Описание: The servo valve G772K620A is a precision control component that represents high-precision, high dynamic response, and high reliability core technologies in the field of high-end electro-hydraulic servo control
As a typical two-stage servo valve, G772K620A has a precise and efficient workflow. The first stage is usually a precision nozzle baffle or jet tube pilot stage, which receives weak electrical signals from the controller and converts them into hydraulic pilot pressure. This pilot pressure drives the second stage spool valve to perform precise displacement. The displacement of the valve core is balanced with the input electromagnetic force through the built-in mechanical feedback rod (force feedback), thereby achieving a precise linear relationship between the valve core opening and the input signal. This closed-loop feedback mechanism ensures extremely high control accuracy and anti-interference ability.
The servo valve G772K620A is widely used in aircraft control surfaces, rocket thrust vectoring control, vibration test benches, material testing machines, precision injection molding machines, and other applications that require ultimate control performance due to its excellent dynamic response (usually with a bandwidth of over 100Hz), extremely high control resolution, and excellent stability.
