1、先要檢查電(dian)(dian)(dian)磁閥(fa)是(shi)否與(yu)選型參數一致，比如電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)(ya)、介質壓(ya)(ya)(ya)力、壓(ya)(ya)(ya)差等，尤其是(shi)電(dian)(dian)(dian)源(yuan)，如果搞錯(cuo)，就(jiu)會燒壞線(xian)(xian)圈(quan)。電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)(ya)應滿足額定電(dian)(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)(dian)壓(ya)(ya)(ya)波動范圍：交流(liu)(liu)+10%~-15%，直流(liu)(liu)+10%~-10%，平時線(xian)(xian)圈(quan)組件不宜拆(chai)開。 

2、一般電磁閥的(de)電磁線圈部件應豎(shu)直(zhi)向上，豎(shu)直(zhi)安裝在(zai)水平于(yu)地面的(de)管(guan)道，如果(guo)受空間限制(zhi)或工(gong)況要求(qiu)必須按側立安裝的(de)，需在(zai)選型訂貨時提出。否則可(ke)能(neng)造成電磁閥不能(neng)正常工(gong)作。 

3、接(jie)管(guan)之(zhi)前要(yao)對管(guan)道進行沖洗，把管(guan)道中(zhong)(zhong)的(de)金屬粉末及密封材料殘留物，銹垢(gou)等清除。要(yao)注意介(jie)(jie)質的(de)潔凈(jing)度，如果介(jie)(jie)質內(nei)混有塵垢(gou)，雜質等妨礙電磁閥的(de)正常工作，管(guan)道中(zhong)(zhong)應裝過濾器或濾網。 

4、如(ru)果介質會起(qi)水錘現象(xiang)，那么應(ying)該(gai)選用具防(fang)水錘功能(neng)的電磁(ci)閥或采取相應(ying)的防(fang)范措施。 

5、電(dian)磁閥前(qian)后應(ying)加手(shou)動(dong)切斷閥，同時應(ying)設旁路，便于電(dian)磁閥在故障時維(wei)護。
