ASCO電磁閥選型參數(shù)首先應(yīng)該依次遵循安全性,，可靠性,，適用性，經(jīng)濟(jì)性四大原 則,，其次是根據(jù)六個(gè)方面的現(xiàn)場(chǎng)工況（即管道參數(shù),、流體參數(shù)、壓力參數(shù),、電氣參數(shù),、動(dòng)作方式,、特殊要求進(jìn)行選擇）。
選型依據(jù)：
1,、根據(jù)管道參數(shù)選擇電磁閥的：通徑規(guī)格（即DN）,、接口方式
1）按照現(xiàn)場(chǎng)管道內(nèi)徑尺寸或流量要求來(lái)確定通徑（DN）尺寸；
2）接口方式,，一般>DN50要選擇法蘭接口,，≤DN50則可根據(jù)用戶需要自由選擇。
2,、根據(jù)流體參數(shù)選擇電磁閥的：材質(zhì),、溫度組
1）腐蝕性流體：宜選用耐腐蝕電磁閥和全不銹鋼；食用超凈流體：宜選用食品級(jí)不銹鋼材質(zhì)電磁閥,；
2）高溫流體：要選擇采用耐高溫的電工材料和密封材料制造的電磁閥,，而且要選擇活塞式結(jié)構(gòu)類型的；
3）流體狀態(tài)：大至有氣態(tài),，液態(tài)或混合狀態(tài),，特別是口徑大于DN25時(shí)一定要區(qū)分開來(lái)；
4）流體粘度：通常在50cSt以下可任意選擇,，若超過(guò)此值,，則要選用高粘度電磁閥。
3,、根據(jù)壓力參數(shù)選擇電磁閥的：原理和結(jié)構(gòu)品種
1）公稱壓力：這個(gè)參數(shù)與其它通用閥門的含義是一樣的,，是根據(jù)管道公稱壓力來(lái)定；
2）工作壓力：如果工作壓力低則必須選用直動(dòng)或分步直動(dòng)式原理,；zui低工作壓差在0.04Mpa以上時(shí)直動(dòng)式,、分步直動(dòng)式、先導(dǎo)式均可選用,。
4,、電氣選擇：電壓規(guī)格應(yīng)盡量?jī)?yōu)先選用AC220V、DC24較為方便,。
5,、根據(jù)持續(xù)工作時(shí)間長(zhǎng)短來(lái)選擇：常閉、常開,、或可持續(xù)通電
1）當(dāng)電磁閥需要長(zhǎng)時(shí)間開啟,，并且持續(xù)的時(shí)間多于關(guān)閉的時(shí)間應(yīng)選 用常開型；
2）要是開啟的時(shí)間短或開和關(guān)的時(shí)間不多時(shí),，則選常閉型,；
3）但是有些用于安全保護(hù)的工況，如爐,、窯火焰監(jiān)測(cè),，則不能選常開的,，應(yīng)選可長(zhǎng)期通電型。分為直動(dòng)式,，先導(dǎo)式,，手動(dòng)復(fù)位閥。
6,、根據(jù)環(huán)境要求選擇輔助功能：防爆,、止回、手動(dòng),、防水霧,、水淋、潛水,。
