該閥采用一次開(kāi)閥和二次開(kāi)閥連在一體，主閥和導(dǎo)閥分步使電磁力和壓差直接開(kāi)啟主閥口。當(dāng)線(xiàn)圈通電時(shí)，產(chǎn)生電磁力使動(dòng)鐵芯和靜鐵芯吸合，導(dǎo)閥口開(kāi)啟而導(dǎo)閥口設(shè)在主閥口上，且動(dòng)鐵芯與主閥芯連在一起，此時(shí)主閥上腔的壓力通過(guò)導(dǎo)閥口卸荷，在壓力差和電磁力的同時(shí)作用下使主閥芯向上運(yùn)動(dòng)，開(kāi)啟主閥介質(zhì)流通。當(dāng)線(xiàn)圈斷電時(shí)電磁力消失，此時(shí)動(dòng)鐵芯在自重和彈簧力的作用下關(guān)閉導(dǎo)閥孔，此時(shí)介質(zhì)在平衡孔中進(jìn)入主閥芯上腔，使上腔壓力升高，此時(shí)在彈簧復(fù)位和壓力的作用下關(guān)閉主閥，介質(zhì)斷流。結(jié)構(gòu)合理，動(dòng)作可靠，在零壓差時(shí)工作也可靠。如：ZQDF，ZS，2W等。
