CC series ultra-high vacuum flapper valve by hand wheel with screw drive, the drive lever (pull) dynamic link mechanism, drive along the axial movement of the valve plate, achieve the valve open or closed, so as to achieve ultra-high vacuum system object on or off the air flow. In the structural design is reasonable, beautiful in appearance, and has a smooth operation, small size, flow rate, reliable, good sealing performance and long life, etc., it can be widely used in ultra-high vacuum equipment.
Suitable working medium is clean air and non-corrosive gases.
