Both side seal, low torque, Dovetail, Online repairing, double eccentric butterfly valve
Features:
Size DN100-DN500mm,disc is flat shape, allowing bigger rubbish to flow through. DN500 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.
Online repairing by EPOXY. The special technology can help user to repair the Double Eccentric Flange Butterfly Valve without taking the valve out of the pipeline. The user only needs to repair it from the exterior of the butterfly valve without going into the pipeline. Please consult the factory and we will show you how to repair the BV when the rubber seal is damaged.
