就工作原理而言,二通插装阀相当于—个液控单向阀。A和B为主油路仅有的两个工作油口(称为二通阀),X为控制油口。改变控制油口的压力,即可控制A、B油口的通断。当控制口无液压作用时,阀芯下部的液压力超过弹簧力,阀芯被顶开,A与B相通,至于液流的方向则视A、B口的压力大小而定。控制口有液压作用,当px≥pA、px≥pB时,才能保证A口与B口之间关闭。这样,就起逻辑元件的“非”门作用,故也称为逻辑阀。

插装阀按控制油的来源可分为两类:第一类为外控式插装阀,控制油由单独动力源供给,其压力与A、B口的压力变化无关,多用于油路的方向控制;第二类为内控式插装阀,控制油引白阀的A或B口,并分为阀芯带阻尼孔与不带阻尼孔两种,应用比较广泛。
