ZQDF—2（或-3）用于蒸汽，否則易引起誤動(dòng)作。多功能電磁閥則可通通于氣.液體。較好訂時(shí)告明介質(zhì)狀態(tài)，安裝用戶就不必再調(diào)式。介質(zhì)溫度不同規(guī)格產(chǎn)品，否則線圈會(huì)燒掉，密封件老化，嚴(yán)重影響壽命命。介質(zhì)粘度，通常在50CST以下。若超過(guò)此值，通徑大于15MM用多功能電磁閥作特殊訂貨。通徑小于15MM訂高粘度電磁閥。介質(zhì)清潔度不高時(shí)都應(yīng)在電磁閥前配裝反沖過(guò)濾閥，壓力低時(shí)尚可選用直動(dòng)膜片式電磁閥作例如CD—P。介質(zhì)若是定向流通，且不允許倒流ZDF—N和ZQDF—N單需用雙向流通，請(qǐng)作特殊要求提出。介質(zhì)溫度應(yīng)選在電磁閥允許范圍之內(nèi)。</p><p style="text-indent:25px">防爆電磁閥閥門的使用溫度：閥門的使用溫度是由制造閥門的材質(zhì)所確定的。閥門常用材料的使用溫度如下：灰鑄鐵閥門使用溫度為一15~250℃；可鍛鑄鐵閥門使用溫度為一15~250℃；球墨鑄鐵閥門使用溫度為一30~350℃；高鎳鑄鐵閥門較高使用溫度為400℃；碳素鋼閥門使用溫度為一29~450℃，在JB/T3595一93標(biāo)準(zhǔn)中推薦使用溫度t<425℃；1Cr5Mo、合金鋼閥門較高使用溫度為550℃；12Cr1MoVA、合金鋼閥門較高使用溫度：570℃；1Cr18Ni9Ti、1Cr18Ni12Mo2Ti不銹鋼閥門使用溫度為一196~600℃；銅合金閥門使用溫度為一273~250℃。電磁閥較高工作壓差應(yīng)小于電磁閥的較大標(biāo)定壓力。</p><div
