2、爆炸性環(huán)境：必須選用相應(yīng)防爆等級產(chǎn)品，露天安裝或粉塵多場合應(yīng)選用防水，防塵品種。
3、電磁閥公稱壓力應(yīng)超過管內(nèi)高工作壓力。 1、介質(zhì)特性
1）質(zhì)氣，液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥；
2）介質(zhì)溫度不同規(guī)格產(chǎn)品，否則線圈會燒掉，密封件老化，嚴(yán)重影響壽命命；
3）介質(zhì)粘度，通常在50cst以下。若超過此值，通徑大于15mm時，用多功能電磁閥；通徑小于15mm時，用高粘度電磁閥。
4）介質(zhì)清潔度不高時都應(yīng)在電磁閥前配裝反沖過濾閥，壓力低時，可選用直動膜片式電磁閥；
5）介質(zhì)若是定向流通，且不允許倒流，需用雙 pvv21-1x/040-046rb15ddmc
