GIQ series pneumatic high vacuum butterfly valve is suitable for connecting or cutting off air flow in high vacuum system. The valve is powered by compressed air, changes the direction of the air path through the electromagnetic reversing valve, and performs the cylinder pushing, so that the valve plate fixed on the rotating shaft rotates 90 ° to realize the opening and closing of the valve.
The applicable working medium is air and non corrosive gas.
