"V Series" Roughing pump valve V-025RV
This is a type-L valve that can be used in high vacuum range of up to 10-4Pa. This valve uses fluoro rubber (Viton) O-Ring for the vacuum seal and the shaft seal. Ideal as a valve for high vacuum equipment, or a roughing pump valve for the ultra-high vacuum equipment
Components
Features
- Can be used up to high vacuum range
Can be used in high vacuum range of about 10-4Pa. (Fluorine grease is used only on the shaft seal.) - Open/Close position sensor switch
The air cylinder used in the compressed air powered valves has a position sensor switch for opening and closing.
