Carbon Steel base coated with bronze + PTFE interior for lubricant and tin exterior to prevent rusty.

Online repairing by EPOXY:
The user only needs to repair the rubber seal from the exterior of the butterfly valve without going into the pipeline. The total repairing time could be around less than 1 hr for all kinds of the size.
Arch shape disc design :
Reduce head loss and minimize turbulence
Flow thru disc-energy saving, lower pumping cost
Rubber Seat:
Epoxy injected on the backside of groove
Dovetail design can tight the rubber seal
Multi ribs on the seal-reduce operation torque
Seal fixed in the groove and epoxy on the back side as a wedge, no worry of loosen
No need bolting and permanent positioned , decrease nut loose & hole rusting
