SMC電磁閥選型依據：
一(yi)、根據管道參數選擇電磁閥的：通徑規(gui)格(ge)（即DN）、接(jie)口方式
1、按照現(xian)場管道內徑尺寸或流量(liang)要求來確定通徑（DN）尺寸。
2、接(jie)口方式，一般>DN50要選擇(ze)(ze)法蘭接(jie)口，≤DN50則(ze)可根(gen)據(ju)用戶需要自由(you)選擇(ze)(ze)。
二、根據(ju)流體參數選擇電磁閥的：材(cai)質、溫度組
1、腐(fu)蝕(shi)性流體：宜選用耐腐(fu)蝕(shi)電磁(ci)閥和全不銹鋼；食(shi)用超凈流體：宜選用食(shi)品級不銹鋼材質電磁(ci)閥。
2、高溫流體：要選擇(ze)采用耐高溫的電(dian)工材料和密封(feng)材料制造的電(dian)磁閥(fa)，而且要選擇(ze)活塞式結構類型的。
3、流體狀態(tai)：大(da)至有氣態(tai)，液態(tai)或混合狀態(tai)，特(te)別(bie)是口徑大(da)于(yu)DN25訂貨(huo)時一定要區(qu)分開(kai)來(lai)。
4、流(liu)體粘度：通常在50cSt以下可(ke)任意選擇(ze)，若超過此(ci)值，則要(yao)選用高粘度電磁閥。
三、根(gen)據壓力(li)參數選擇電磁閥的：原(yuan)理和結(jie)構(gou)品種
1、公稱(cheng)壓(ya)力：這個參數與其它(ta)通用閥(fa)門的含義是一樣的，是根據管(guan)道公稱(cheng)壓(ya)力來定(ding)。
2、工作壓力(li)：如果工作壓力(li)低(di)則(ze)必須選用(yong)直(zhi)(zhi)動(dong)(dong)或分(fen)(fen)步(bu)直(zhi)(zhi)動(dong)(dong)式(shi)(shi)原理；zui低(di)工作壓差在0.04Mpa以上時直(zhi)(zhi)動(dong)(dong)式(shi)(shi)、分(fen)(fen)步(bu)直(zhi)(zhi)動(dong)(dong)式(shi)(shi)、先導式(shi)(shi)均可選用(yong)。
四、電(dian)氣(qi)選(xuan)擇：電(dian)壓規格應(ying)盡(jin)量優(you)先選(xuan)用AC220V、DC24較為方便(bian)。
五(wu)、根據持續工作時間長短來選擇：常閉、常開、或可持續通電
1、當電(dian)磁(ci)閥需要長時(shi)(shi)間開啟，并(bing)且(qie)持(chi)續的時(shi)(shi)間多(duo)余(yu)關(guan)閉的時(shi)(shi)間應選用常開型。
2、要是開啟的(de)時間短或(huo)開和(he)關的(de)時間不多(duo)時，則選常閉型。
3、但是有些用于(yu)安全保護(hu)的工(gong)況，如(ru)爐、窯火(huo)焰監(jian)測，則不(bu)能選常開(kai)的，應選可長期通電型。
