Ordinary three-eccentric multi-level metal seal seal butterfly valve, it takes from two or more layers of metal and non-sheet metal composite to made of sealing ring, the ring and bolts fixed on the butterfly plate.
This structure of the laminated metal hard seal butterfly valve, due to the sealing ring on the non-metallic sheet of physical and chemical properties, can only be used to the general non-high temperature and non-high pressure and non-corrosive conditions.
have outstandarding festures in below :
1.Since the sealing ring is made entirely of metal material, which greatly improves the service life of the valve.
2.Sealing material is made of metal , but not rubber and PTFE series,valve can adapt to wide temperature range, from -196 to 700 ℃.
3.Valve can be used for widely range media such as partical material. This valve is a two-stage stem design, which can reduce the flow resistance to valve in in pipeline.
