Types:triple offset,double offset,concentric butterfly valve
Sealing: soft seal PTFE,EPDM,NBR or metal seal hard SS, laminated SS+graphite
Features: Butterfly valve is for regulating or cut off in the pipeline and very low efficient cost. It is applied in a lot range of pipeline like petroleum,chemical, power plant,water supply etc.
The triple offset butterfly valve in laminated sealing reaches the bi-directional sealing zero leakage in both way,the valve sealing could be on the disc,body or the replaceable seat ring meet different choices.
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.
The concentric butterfly valve more commonly used in low pressure such as PN10/16, the valve sealing is EPDM / NBR/ VITON / PTFE soft seat material lined in body, the usual body material is carbon steel WCB, cast iron GG25/GGG40/50,bronze C95800.
