The vacuum solenoid valve can realize accurate gas control. The vacuum treatment of pipeline is realized by electromagnetic principle, which is mainly used in vacuum pipeline or linkage control system with vacuum pump. The vacuum solenoid valve has the advantages of simple structure, high reliability and fast response speed. The vacuum solenoid valve is light in design and easy to install and use. The vacuum solenoid valve has fast response ability, which can quickly turn on or off the gas flow and realize the precise control of the vacuum system.
