1.The self-sealing center-line butterfly valve is a newly designed and innovative valve with a micro interference between the rubber disc and valve channel, which can decrease abrasions to the sealing face, increasing the service life of valves.
2.With a self-sealing structure, the sealing properly of the butterfly valve is proportional fluid pressure, allowing the valves to withstand high pressures.
3.The sealing lip on the rubber disc can remove mud and dirt when the valve closes.
4.The outer and inner surfaces of the grooved valve are coated with a high quality epoxy powder, so the paint coat is complete and even, making the valve safe for use in the food, beverage and pharmaceutical industries.
