The structure of plate butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type. According to the sealing form, it can be divided into soft sealing type and hard sealing type. The soft seal type generally uses the rubber ring seal, the hard seal type usually uses the metal ring seal. The advantages of pneumatic butterfly valve include convenient opening and closing, labor saving, low fluid resistance, simple structure, small volume, light weight and so on.
