閥芯在不同的位置時，
電磁閥的通路也就不同,。閥芯的工作位置有幾個,，該博世力士樂就叫幾位電磁閥：
閥體上的接口，也就是電磁閥的通路數(shù),，有幾個通路口,，該電磁閥就叫幾通電磁閥。
電磁閥安裝后,，一般所有接口都應該是連接好了的,，所謂工作位置指的是閥芯的位置。
博世力士樂的閥芯在線圈不通電時處在甲位置,，在線圈通電時處在乙位置,，
閥芯在不同位置時,，對各接口起到或接通或封閉的作用

德國力士樂REXROTH電磁閥部分型號如下：

適用性：
1）質(zhì)氣，液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥,；
2）介質(zhì)溫度不同規(guī)格產(chǎn)品,，否則線圈會燒掉，密封件老化,，嚴重影響壽命命,；
3）介質(zhì)粘度，通常在50cSt以下,。若超過此值,，通徑大于15mm時，用多功能電磁閥,；
通徑小于15mm時,，用高粘度電磁閥。
4）介質(zhì)清潔度不高時都應在電磁閥前配裝反沖過濾閥,，壓力低時,，可選用直動膜片式電磁閥；
5）介質(zhì)若是定向流通,，且不允許倒流
