AIRTAC電(dian)(dian)(dian)磁閥(fa)的(de)用(yong)(yong)途電(dian)(dian)(dian)磁閥(fa)用(yong)(yong)于(yu)(yu)(yu)液(ye)體(ti)和氣體(ti)管(guan)(guan)路的(de)開(kai)(kai)關(guan)控(kong)(kong)(kong)(kong)制(zhi)，是(shi)兩(liang)(liang)位(wei)DO控(kong)(kong)(kong)(kong)制(zhi)。般用(yong)(yong)于(yu)(yu)(yu)小型(xing)管(guan)(guan)道的(de)控(kong)(kong)(kong)(kong)制(zhi)。電(dian)(dian)(dian)動閥(fa)用(yong)(yong)于(yu)(yu)(yu)液(ye)體(ti)、氣體(ti)和風系統管(guan)(guan)道介質(zhi)流(liu)量(liang)(liang)的(de)模(mo)擬量(liang)(liang)調節，是(shi)AI控(kong)(kong)(kong)(kong)制(zhi)。在大型(xing)閥(fa)門(men)和風系統的(de)控(kong)(kong)(kong)(kong)制(zhi)中也可(ke)(ke)以(yi)用(yong)(yong)電(dian)(dian)(dian)動閥(fa)做兩(liang)(liang)位(wei)開(kai)(kai)關(guan)控(kong)(kong)(kong)(kong)制(zhi)。電(dian)(dian)(dian)磁閥(fa)只(zhi)能用(yong)(yong)作(zuo)(zuo)開(kai)(kai)關(guan)量(liang)(liang)，是(shi)DO控(kong)(kong)(kong)(kong)制(zhi)，只(zhi)能用(yong)(yong)于(yu)(yu)(yu)小管(guan)(guan)道控(kong)(kong)(kong)(kong)制(zhi)，常見(jian)于(yu)(yu)(yu)DN50及以(yi)下管(guan)(guan)道，往上就很(hen)少了。 　　電(dian)(dian)(dian)動閥(fa)可(ke)(ke)以(yi)有AI反饋信號，可(ke)(ke)以(yi)由DO或AO控(kong)(kong)(kong)(kong)制(zhi)，比較見(jian)于(yu)(yu)(yu)大管(guan)(guan)道和風閥(fa)等。 　　1.開(kai)(kai)關(guan)形式電(dian)(dian)(dian)磁閥(fa)通(tong)過線(xian)圈驅動，只(zhi)能開(kai)(kai)或關(guan)，開(kai)(kai)關(guan)時動作(zuo)(zuo)時間短(duan)。電(dian)(dian)(dian)動閥(fa)的(de)驅動般是(shi)用(yong)(yong)電(dian)(dian)(dian)機，開(kai)(kai)或關(guan)動作(zuo)(zuo)完成(cheng)需要定的(de)時間模(mo)擬量(liang)(liang)的(de)，可(ke)(ke)以(yi)做調節。 　　2.工作(zuo)(zuo)性質(zhi)電(dian)(dian)(dian)磁閥(fa)般流(liu)通(tong)系數(shu)(shu)很(hen)小，而(er)且(qie)工作(zuo)(zuo)壓力差(cha)很(hen)小。比如(ru)般25口徑的(de)電(dian)(dian)(dian)磁閥(fa)流(liu)通(tong)系數(shu)(shu)比15口徑的(de)電(dian)(dian)(dian)動球閥(fa)小很(hen)多。
