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


Double Eccentric Flange Type Butterfly Valve with worm gear (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.


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