Blue Double Eccentric Butterfly Valve DI Disc With Stainless Steel Ring

DI Disc With Stainless Steel Ring Double Eccentric Butterfly Valve

Description:

    AFC's Double Eccentric Flange Tpye Butterfly Valve (we call abbreviated FBGD) is butterfly valve with advanced design. With double eccentric design and soft rubber seal, 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. 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.
