Vacuum butterfly valve is used in chemical, building, power station, glass etc industrial ventilation, environmental protection engineering of dust air cooling or hot gas pipeline to adjust or cut device as gas medium.
The specifications of Vacuum butterfly valve are:
1. Normal pressure: 0.25MPa
2. Testing pressure: 0.4MPa
3. Working pressure: 0.25MPa
4. Applicable medium: No corrosion of saturated steam
5. Applicable temperature: ≤ 120, ≤ 200
6. Vacuum light leakage rate: ≤ 6.67× 10-2P
7. Flange connection size: GB2555~2556-81
The structural features of Vacuum butterfly valve are: Vacuum butterfly valve adopts line type disc plate and short structure a new type of structure design and manufacture of steel plate welding. Its structure is compact, weight is light, convenient to install, flow resistance is small, and turnover is big and avoid influence of high temperature expansion. There is no connecting rod, bolt etc, its working is reliable and service life is long. It's convenient to multistation installation and is not affected by the medium flow direction
Vacuum butterfly valve is a kind non-closing butterfly valve and widely used in building, metallurgy, mine, electric power etc pipeline which medium temperature is ≤ 300 degree and normal pressure is 0.1Mpa to connect, open and close, or adjust medium flow.
