1.The self-sealing center-line type butterfly valve is one kind of new designed and innovative valve with micro interference between rubber disc and valve channel which can decrease the abrasion of the sealing face and increase the life of valves
2.With self-sealing structure, the sealing property is proportional to fluid pressure,so the valves can resist very high pressure.
3. the sealing lip on the rubber disc can remove the mud and dirt during the closing of the valves.
4. Outside and inside surface of the valve is done with high quality of epoxy powder, so the painting is more complete and even, and can be used on drinking, food and pharmacy etc.
