Pneumatic diaphragm valve is a special form of truncation pneumatic valve (2)

diaphragm is by the pneumatic valve, the opening and closing is a soft material gap, its coelomic cavity and special form of separation of pneumatic valve cover. Lining of the legal procedure and the limitation of the pneumatic diaphragm valve manufacturing technology, a growing body lining membrane manufacturing process is difficult, it is not a general large diameter diaphragm below DN mm or less pipe is used, suitable. Due to the limitation of membrane material, low pressure and temperature of the pneumatic diaphragm valve is not high. Generally no more than degrees. The diaphragm has good corrosion resistance, it is usually used for corrosive medium, using the equipment and pipes. Wen is the media for pneumatic diaphragm valve diaphragm and diaphragm material limit, pneumatic diaphragm valve lining material lining material recommended for medium temperature and table - As shown in. Diaphragm temperature membrane materials, recommend and media applications.
table - Diaphragm temperature and lining materials for the use of media note: this table refers to the percentage of the mass fraction of all.
