Pneumatic diaphragm valve's relationship with truncated pneumatic valve

pneumatic diaphragm valve is a kind of special form of truncation pneumatic valve, the opening and closing is a diaphragm made with soft materials, it will pneumatic valve body cavity and cavity in pneumatic valve cover. Due to the pneumatic valve lining the limitation of process and manufacturing technics of diaphragm, pneumatic valve body lining and larger diaphragm manufacturing process is very difficult, so the pneumatic diaphragm valve should not be used for large diameter, commonly used in the pipeline under the DN mm or less. Due to limited by diaphragm material, pneumatic diaphragm valve is suitable for the occasion of low pressure and temperature is not high. Generally not more than degrees. Due to the pneumatic diaphragm valve has good anti-corrosion performance, so the more commonly used in corrosive medium equipment and piping. Due to the use of pneumatic diaphragm valve temperature suitable medium by the pneumatic diaphragm valve pneumatic body lining materials and the limitation of the diaphragm material, pneumatic valve pneumatic diaphragm body lining material recommended temperature and suitable medium; Pneumatic diaphragm valve diaphragm material recommended temperature and the suitable medium see
the use of pneumatic valve pneumatic diaphragm body lining material temperature and suitable medium note: percentage in the table refers to the quality score.
