The double way sealing butterfly valve have float seat, there have O ring between float seat and valve body, it can be used for double side direction of the medium in pipeline.
The bi-directional triple eccentric butterfly valve body seat ring is surfacing of stainless steel Cr13 or 2205,hard and wear resistant, long life service.
When the medium is chemical, then the seal ring on the disc can choosed PTFE material, which is possible to used in corrosive medium,stable performance.
