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. 

Materials: carbon steel, alloy steel, stainless steel, duplex steel,bronze, Inconel,Hastelloy,Monel, Incoloy etc.

Carbon Steel WCB,WCC, WC6,WC9,C5, C12 etc.

Low Carbon Steel LCB,LCC etc.

Stainless Steel CF8, CF8M, CF3M,CF8C etc.
