BURKERT電磁閥主要選型的資料有哪幾部分，BURKERT電磁閥
常開型正好相反。如小于φ6流量通徑的BURKERT電磁閥。 　 BURKERT電磁閥采用次開閥和二次開閥連在體，主閥和導閥分步使電磁力和壓差直接開啟主閥口。當線圈通電時，產生電磁力使動鐵芯和靜鐵芯吸合，導閥口開啟而導閥口設在主閥口上，且動鐵芯與主閥芯連在起，此時主閥上腔的壓力通過導閥口卸荷，在壓力差和電磁力的同時作用下使主閥芯向上運動，開啟主閥介質流通。當線圈斷電時電磁力消失，此時動鐵芯在自重和彈簧力的作用下關閉導閥孔，此時介質在平衡孔中進入主閥芯上腔，使上腔壓力升高，此時在彈簧復位和壓力的作用下關閉主閥，介質斷流。
原理： 它是種直動和導式相結合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力導小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。　特點： 在零壓差或真空、高壓時亦能可*動作，但功率較大，要求必須水平安裝。
導式電磁閥
原理：通電時，電磁力把導孔打開，上腔室壓力迅速下降，在關閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。　特點： 流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。　2.電磁閥從閥結構和材料上的不同與原理上的區別，分為六個分支小類：　直動膜片結構、分步重片結構、導膜式結構、直動活塞結構、分步直動活塞結構、導活塞結構。
