The electric high vacuum butterfly valve adopts a rotary electric and electronic regulating valve driving device to drive the valve stem and valve plate to perform opening and closing actions. The vacuum butterfly valve can be controlled by switching the external power supply (using a manual switch or computer control) or external input signals to achieve the purpose of opening or closing the vacuum valve or controlling the middle position, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum pipeline. The valve plate of the valve body adopts a clamping structure to clamp the sealing element of the valve plate, which can be used not only in vacuum state but also in low pressure state. Electric high vacuum butterfly valve is used to connect or cut off the airflow in the vacuum pipeline. The applicable medium for electric high vacuum butterfly valves is pure air and non corrosive gases.
