Application of double eccentric double flanged butterfly valve:
1. The high- performance double-flanged butterfly valve series are the renewed products that are desighed and debeloped by the company's new product debelopment department according to the request of many clients. This kind of balbe can reach the up-to-date world adbanded lebel b adoptig the successful ecperiences obtained through the butterfly valve reseach since the half acentury tocreate the unique structure so as to gain high-quality performances, The calce, charactered, high pressure differentce, free and labor-saving actuating, is widely used for cutting off media floeing in the high and medium-pressure industrial pipeline for water supply, drainage, metallurgy, peteoleum chmicals, electric power.
Feature of the high perfomance double flange butterfly Valve
1. The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose if pressing out the sealing surface has small frictional resistance. When shutting off, it cleses more and more, so this makes sealing performance reliable, Opening can ensure that the sealing.
2. The special geometric structure makes the butterfly valve free of defect that other butterfly balves are unable to be sealed will due to excessively opening, so as to gurantee good sealing of the surface.
3. The double eccentric butterfly valve structure can gurantee that the valve fundtions mormally under high prssure and overcome the shortcomings that other valve easily leak due to sest deformation when they work under high pressure.
