MAC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)就(jiu)是用電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)力開(kai)啟或(huo)關(guan)閉(bi)的(de)(de)(de)閥(fa)(fa)(fa)(fa)門。用在氣(qi)路或(huo)液路上。結構(gou)和種類(lei)非常(chang)多，但(dan)是動(dong)作原理都基本一(yi)(yi)(yi)(yi)樣。 控(kong)制電(dian)(dian)(dian)(dian)(dian)(dian)路輸入一(yi)(yi)(yi)(yi)個電(dian)(dian)(dian)(dian)(dian)(dian)信號，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)內就(jiu)相應產生一(yi)(yi)(yi)(yi)個磁(ci)(ci)(ci)信號，這(zhe)個磁(ci)(ci)(ci)信號驅動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)鐵產生一(yi)(yi)(yi)(yi)個動(dong)作，閥(fa)(fa)(fa)(fa)門的(de)(de)(de)開(kai)閉(bi)就(jiu)產生一(yi)(yi)(yi)(yi)個對應。 MAC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)有別(bie)于其(qi)他閥(fa)(fa)(fa)(fa)門（手控(kong)、氣(qi)控(kong)、液控(kong)、機控(kong)......）的(de)(de)(de)突出(chu)特點是便(bian)于實現(xian)自(zi)(zi)動(dong)控(kong)制。電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)用在一(yi)(yi)(yi)(yi)些凈水器里，可(ke)能是這(zhe)些地(di)方需要自(zi)(zi)動(dong)控(kong)制或(huo)者聯動(dong)。 MAC電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)為分(fen)步動(dong)作直(zhi)接先導式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)，可(ke)根據斷電(dian)(dian)(dian)(dian)(dian)(dian)時所處開(kai)、關(guan)狀態的(de)(de)(de)不同，可(ke)分(fen)為常(chang)閉(bi)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)和常(chang)開(kai)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)。常(chang)閉(bi)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)，線圈通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)后，銜鐵在電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)力作用下(xia)先帶動(dong)副(fu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)塞提(ti)起，主(zhu)(zhu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)杯(bei)上的(de)(de)(de)流(liu)體經副(fu)閥(fa)(fa)(fa)(fa)流(liu)走，減(jian)少了作用在主(zhu)(zhu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)杯(bei)上的(de)(de)(de)壓(ya)力，當(dang)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)杯(bei)上的(de)(de)(de)壓(ya)力減(jian)少到一(yi)(yi)(yi)(yi)定值時，銜鐵帶動(dong)主(zhu)(zhu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)杯(bei)，并(bing)利(li)用壓(ya)差而使主(zhu)(zhu)閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)杯(bei)開(kai)啟，介質(zhi)流(liu)通(tong)。線圈斷電(dian)(dian)(dian)(dian)(dian)(dian)后，電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)力消失(shi)，銜鐵因自(zi)(zi)重下(xia)落(luo)復位。
