    DI Disc Stainless Steel Ring Butterfly Valve Epoxy Coated Worm Gear Available


    Description:

    AFC's Double Eccentric Flange Butterfly Valve is a newly advanced design butterfly valve. Due to 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 DN150-DN300mm,disc is flat shape, allowing bigger rubbish to flow by. DN350 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.


    Feature:


    . The valve is made of DI body and DI disc.
    . Advanced newly design with dovetail seal design and captured by epoxy on the back, with multiple raised ring to have more contact with disc but less friction during closure.
    . The double eccentric design provides less contact area of seal with disc, and less stress at the open position of the disc.
    . The disc design with arch shape and thru disc can provide better flow capacity, stronger and less weight
    . The shaft and disc connection with tangential pin which can be exchangeable and provide
    rigid connection.
    . The DN 100-500MM use flat disc, and DN 600-1200MM use arch shape disc.
    . Epoxy coated interior and exterior.
    . Valve design meets or exceeds EN 593.
    . Top flange connection meets ISO 5211-1982, and F/F meets EN 558-1 series 13 & 14.
