ASCO電磁閥EF8551A001MS現(xiàn)貨ASCO電磁閥的分布直動(dòng)式:它是一種直動(dòng)式和先導(dǎo)式相結(jié)合的原理。當(dāng)入口與出口沒有壓差時(shí),通電后電磁力直接打開先導(dǎo)孔連接主閥活塞依次向上提起,閥門打開;當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,電磁力先打開先導(dǎo)孔,主閥活塞上腔壓力下降,從而利用壓差和電磁力拉動(dòng)主活塞,閥口打開;斷電時(shí),靠彈簧復(fù)位關(guān)閉先導(dǎo)孔,主活塞上腔增壓,推動(dòng)主活塞向下移動(dòng),閥關(guān)閉。常開式與常閉式相反。ASCO防爆電磁閥工作制式:分長期工作制,反復(fù)短時(shí)工作制和短時(shí)工作制三種。防爆電磁閥均為長期工作制,即線圈允許長期通電工作。對(duì)于長時(shí)間閥門開通只有短時(shí)關(guān)閉的情況,則宜選用常開電磁閥。用在短時(shí)工作制而批量又很大時(shí),可作特殊訂貨以降低功耗。EF8320G174 EF8320G176 EF8320G184 EF8320G186 EFG551H401MOEF8551A001MS SCG551A201 8551B401 EF8344G370OFSF8263G206V NFG353A043 SCG353A051 SCXE353.60SCG551A005MS SCG551A017MS WT8551A001MS NF8327B112SCG551A018MS SCG551A001MS SCG551A002MS EF8320G203SCG531D001MS WSNF8551A421 SC8344A074 EF8320G203V ASCO電磁閥EF8551A001MS現(xiàn)貨
