Gid-A series electric high vacuum butterfly valve adopts rotary electric and electronic regulating valve driving device, which can realize the control of valve opening, closing or middle position through the switch of external power supply (controlled by manual position switch or computer) or external input signal, so as to connect or cut off the air flow in vacuum pipeline. The valve plate of the valve adopts the clamping structure to clamp the sealing ring of the valve plate, which has the function of fine-tuning the main sealing.
The applicable working medium is air and non corrosive gas.
