  特點(dian)：

1、力士(shi)樂電(dian)磁閥電(dian)磁閥和(he)全不(bu)(bu)(bu)銹鋼；對于強腐蝕的(de)介 質必須選(xuan)用(yong)隔離(li)膜(mo)片式。中性介質，也宜選(xuan)用(yong)銅(tong)合(he)金(jin)為閥殼材料的(de)電(dian)磁閥，否則(ze)，閥殼中常有銹屑脫(tuo)落，尤其(qi)是動作(zuo)不(bu)(bu)(bu)頻繁的(de)場合(he)。氨(an)用(yong)閥則(ze)不(bu)(bu)(bu)能采用(yong)銅(tong)材。

2、爆炸性環境：必須選用相應防爆等級產品，露天安裝或粉塵多(duo)場(chang)合(he)應選用防水，防塵品種。

3、電磁閥公稱壓(ya)力應(ying)超過管內(nei)zui高工作壓(ya)力。

適用性

1、介質特性

（1）質(zhi)氣(qi)，液(ye)態(tai)或(huo)混(hun)合狀態(tai)分(fen)別選(xuan)用不同品(pin)種的電磁(ci)閥；

（2）介質溫度不同(tong)規格產品，否則線圈會燒掉，密封件老(lao)化，嚴重影響壽命(ming)命(ming)；

（3）介質粘(zhan)度，通常在50cSt以下。若超過此(ci)值，通徑大于15mm時(shi)，用(yong)多(duo)功(gong)能電磁閥(fa)；通徑小于15mm時(shi)，用(yong)高(gao)粘(zhan)度電磁閥(fa)。

（4）介質清潔度(du)不高時(shi)都(dou)應在電磁閥前配裝(zhuang)反沖過濾(lv)閥，壓(ya)力低時(shi)，可(ke)選用(yong)直動膜片式電磁閥；

（5）介質若是定向流通，且不允許倒流。天津(jin)萬寶隆流(liu)體控制設備(bei)有(you)限公(gong)司
