Rubber sealed double eccentric butterfly valve, when the valve is opened, the butterfly plate can quickly leave the valve seat, greatly eliminate the unnecessary excessive extrusion and scraping phenomenon of the butterfly plate and the valve seat, reduce the opening resistance moment, reduce wear and improve the life of the valve seat. Products are widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines for load fluid use.
1.Rubber double eccentric butterfly valve, soft sealing design makes the valve has zero leakage performance.
2.Rubber double eccentric butterfly valve, when the valve is opened, the butterfly plate can quickly leave the valve seat, greatly eliminating the unnecessary excessive extrusion and scraping phenomenon of the butterfly plate and the valve seat, reduce the opening moment, reduce wear, and improve the life of the valve seat.
3.Valve seat design adopts different non-metallic materials according to different customer requirements to meet different working conditions.
4.Rubber double eccentric butterfly valve,external gear anti-blowing valve stem is safe and reliable, in line with the provisions of API 609.
