MAC分步直動(dòng)式電磁閥備現(xiàn)貨
原理：它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時(shí)，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先導(dǎo)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(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。
特點(diǎn)：在零壓差或真空、高壓時(shí)亦能可*動(dòng)作，但功率較大，要求必須水平安裝。
MAC先導(dǎo)式電磁閥 
原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。
特點(diǎn)：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、MAC電磁閥從閥結(jié)構(gòu)和材料上的不同與原理上的區(qū)別，分為六個(gè)分支小類：直動(dòng)膜片結(jié)構(gòu)、分步直動(dòng)膜片結(jié)構(gòu)、先導(dǎo)膜片結(jié)構(gòu)、直動(dòng)活塞結(jié)構(gòu)、分步直動(dòng)活塞結(jié)構(gòu)、先導(dǎo)活塞結(jié)構(gòu)。
3、MAC電磁閥按照功能分類：水用電磁閥、蒸汽電磁閥、制冷電磁閥、低溫電磁閥、燃?xì)怆姶砰y、消防電磁閥、氨用電磁閥、氣體電磁閥、液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥 常開電磁閥、油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。
