隔膜閥本身結(jié)構(gòu)設(shè)計(jì)的原因特適合于超純介質(zhì)或污染嚴(yán)重，十分粘稠的液體、氣體、腐蝕性或惰性介質(zhì)。與控制設(shè)備相結(jié)合時(shí)，隔膜閥更能取代其它傳統(tǒng)控制系統(tǒng)，尤其是適用于固體和易污染的惰性介質(zhì)。產(chǎn)品主要應(yīng)用于生物制藥、食品、行業(yè);以及電力、化工、電鍍、等行業(yè)的工業(yè)水處理中,還被應(yīng)用于半導(dǎo)體晶圓的生產(chǎn)中,隔膜閥是特別適用于運(yùn)送有腐蝕性，有粘性的流體，例如泥漿、食品、藥品、織維性粘合液等，因管線中，隔膜閥的操作機(jī)構(gòu)，是不暴露在運(yùn)送流體中，故不具污染性，也不需要填料，閥桿填料部也不可能會(huì)泄漏。
