Pneuamtic Ultra High Vacuum Flapper Valve Low Leakage For Clean Air And Non Corrosive Gas
Pneuamtic Ultra High Vacuum Flapper Valve
1. Description:
The CC series ultra-high vacuum plug valve is driven by a handwheel with a screw, and the connecting rod mechanism is pushed (pulled) by the transmission rod to drive the valve plate to move axially, realizing the opening or closing of the valve, thereby achieving the purpose of facilitating or cutting off the airflow in the ultra-high vacuum system. Reasonably designed in structure, aesthetically pleasing in appearance, and characterized by stability, small size, large flow channels, and reliable use. The advantages of good sealing performance and long service life can be widely used in ultra-high vacuum equipment. The suitable working medium is clean air and non corrosive gases.
