The GID-A series electric high vacuum butterfly valve adopts a rotary electric and electronic regulating valve drive device, which can be controlled by switching the external power supply (using manual switch or computer control) or external input signals to achieve valve opening, closing or intermediate position control, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum pipeline. The valve plate of the valve adopts a clamping structure, which clamps the sealing ring of the valve plate. It can be used not only in vacuum state but also in low pressure state.  
The applicable working media are air and non corrosive gases.
