Soft Rubber Seal Steam Butterfly Valve , Dovetail Seal Design Double Flanged Butterfly Valve


Both Side Seal​ Ductile Iron Double Flange Double Eccentric Butterfly Valve


AFC's Double Eccentric Flange Butterfly Valve (we call abbreviated FBGD) is a newly advanced design butterfly valve. With double eccentric design and soft rubber seal on the body, the operational toque is one of the lowest among all the butterfly valves and can be sealed in both directions,disc and stem are very strong without any deformation.


With dovetail seal design with multiple groove and internal epoxy stuffed, more than two ways of rubber extension space brings much less compression and wearing between disc and soft seat and prevents the rubber seal to be blowed out.
