Ductile Iron Soft Seated Double Flange Double Eccentric Butterfly Valve​

Description:


AFC's Double Eccentric Flange Butterfly Valve (we call abbreviated FBGD) is an 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. Size DN100-DN500mm,disc is flat shape, allowing bigger rubbish to flow through. DN500 to DN1200mm disc are arch shape with stronger ribs on the back, causing less compression and wearing of seal rubber to increase the life of rubber seal. Also, water head loss reduced a lot and turbulence minimized,thus flow through disc energy is saved and lowering the pumping cost.The DN600 Butterfly Valve can opertated more than 10,000 times and still working.
