    Doubel Eccentric Butterfly Valve with both side seal, low torque, Dovetail, repairing online
     
    Features:
     
       The disc of the BV DN100-DN500mm is flat shape, which allows bigger rubbish to flow through. DN500 to DN1200mm discs are arch shape with stronger ribs on the back, causing less compression and wearing of seal rubber to increase the life of rubber seal.At the same time water head loss can be reduced a lot and turbulence can be minimized,thus lowering the pumping cost and flow through disc energy is saved.
