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.
Online repairing by EPOXY. The special technology can help User can repair the Double Eccentric Flange Butterfly Valve without taking the valve out of the pipeline yhanks for the special technology. 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.
