Features: The double offset butterfly valve the design is stem center line deviated body center line and stem center is deviated seat sealing center. This structure is normally RUBBER,PTFE/RPTFE or PTFE+SS sound sealing performance.
It is mainly used for system drainage of water plants, power plants, steel mill smelting, chemical industry, water source project, environmental facilities construction, etc. It is especially suitable for waterway pipelines and is used as regulation and interception equipment. Compared with the centre butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, longer life and good stability.
