Description
Double Eccentric Flange Butterfly Valve
Features:
. 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 the seal with the 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 a tangential pin can be exchangeable and provide a rigid connection.
. The DN 100-500MM uses a flat disc, and DN 600-1200MM uses arch shape disc.
