，在我們的生產中應用也很多，其工作原理如下：當有電流通過線圈時，產生勵磁作用，固定鐵芯吸合動鐵芯，動鐵芯帶動滑閥芯并壓縮彈簧，改變了滑閥芯的位置，從而改變了流體的方向。當線圈失電時，依靠彈簧的彈力推動滑閥芯，頂回動鐵芯，使流體按原來的方向流動。在我們制氧生產中，分子篩切換系統強制閥的開關就是通過二位四通電磁閥來控制的，氣流分別供至強制閥的活塞兩端。從而來控制強制閥的啟閉。一級強勢供應德國REXROTH電磁，德國Rexroth電磁換向閥是由電磁線圈和磁芯組成，是包含一個或幾個孔的閥體。當線圈通電或斷電時，磁芯的運轉將導致流體通過閥體或被切斷，以達到改變流體方向的目的。力士樂 電磁換向閥的電磁部件由固定鐵芯、動鐵芯、滑閥套、彈簧底座等組成。電磁線圈被直接安裝在閥體上，閥體被封閉在密封管中，構成一個簡潔、緊湊的組合。我們在生產中常用的 電磁換向閥有二位三通。REXROTH電磁閥
