festo電磁閥選型首先應該依次遵循安全性，可靠性，適用性，經濟性四大原電磁閥則，其次是根據六個方面的現場工況（即管道參數、流體參數、壓力參數、電氣參數、動作方式、特殊要求進行選擇）。 　　選型依據： 　　一、根據管道參數選擇電磁閥的：通徑規格(即DN)、接口方式 　　1、按照現場管道內徑尺寸或流量要求來確定通徑（DN)尺寸。 　　2、接口方式，一般>DN50要選擇法蘭接口，≤DN50則可根據用戶需要自由選擇。 　　二、根據流體參數選擇電磁閥的：材質、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：宜選用食品級不銹鋼材質電磁閥。 　　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構類型的。電磁閥
3、流體狀態：大至有氣態，液態或混合狀態，特別是口徑大于DN25訂貨時一定要區分開來。 　　4、流體粘度：通常在50cSt以下可任意選擇，若超過此值，則要選用高粘度電磁閥。 　　三、根據壓力參數選擇電磁閥的：原理和結構品種 　　1、公稱壓力：這個參數與其它通用閥門的含義是一樣的，是根據管道公稱壓力來定。 　　2、工作壓力：如果工作壓力低則必須選用直動或分步直動式原理；zui低工作壓差在0.04Mpa以上時直動式、分步直動式、先導式均可選用。 　　四、電氣選擇：電壓規格應盡量優先選用AC220V、DC24較為方便。 　　五、根據持續工作時間長短來選擇：常閉、常開、或可持續通電 　　1、當電磁閥需要長時間開啟，并且持續的時間多余關閉的時間應選電磁閥
用常開型。 　　2、要是開啟的時間短或開和關的時間不多時，則選常閉型。 　　3、但是有些用于安全保護的工況，如爐、窯火焰監測，則不能選常開的，應選可長期通電型。 　　六、根據環境要求選擇輔助功能：防爆、止回、手動、防水霧、水淋、潛水
