Products overview:
My company developed soft seal centerline wafer butterfly valve and double eccentric flanged butterfly valve structure is compact, 90 ° slewing switch easily, reliable sealing, long service life, is widely used in water plant, power plants, steel mills, paper making, chemical industry, food and so on system in water supply and drainage, used as adjustment and globe.

Features:
1, this valve adopts double eccentric structure, have the close tight sealing function, sealed performance is reliable.
2, nitrile oil resistant rubber sealing deputy stainless steel material selection and matching, long service life.
3, rubber sealing ring can be located in the body, can also be located on the butterfly plate and applicable characteristics of different media, for the user to choose from.
4, the butterfly plate adopts frame structure, high strength, large flow area, small flow resistance.
5, the overall of the lacquer that bake, can effectively prevent rust and replace the sealing seat sealing materials, can be used in different medium.
6, this valve has two-way sealing function, installation time is not controlled by the medium flow direction, and is not affected by spatial location, can be installed in any direction.7, this valve structure unique, flexible operation, and more convenient.
