Low Torque Blue Double Eccentric Butterfly Valve With Dovetail Seal Design

Double Flange Double Eccentric Butterfly Valve Low Torque Advanced Design Series 13 and 14

AFC's Double Eccentric Flange Butterfly Valve (we call abbreviated FBGD) is a newly advanced design butterfly valve.

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

Size DN150-DN350mm,disc is flat shape, allowing bigger rubbish to flow through. 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.

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.
