对于可控式充液阀。控制油通入控制缸的上腔，控制活塞就可使阀芯开启。控制缸上腔接油箱时，控制活塞在弹簧的作用下复位。控制缸下腔与充液油箱是想通的。这两种结构的充液阀都直接安装在液压缸的端部，安装方便，节省了与工作液压缸连接的管道。浸入式结构，即上部全浸在充液油箱中，结构很紧凑，流阻损失很小。但充液油箱必须安装在液压缸的底部，防爆阀 DHA-0631/2/A/WP/M 24DC

常开式充液阀的优点在于充液过程中不需要克服弹簧力，从而减少了吸油阻力。但结构较复杂，制造要求也较高。
常开式充液阀。阀芯在弹簧的作用下停在阀上部，充液阀处于开启状态。当转入工作行程时，先在充液阀的控制口通入压力油，阀芯下行，充液阀关闭。由于阀芯上部面积略大于其下部面积，故随着液压缸油压的升高，充液阀越关越紧。当活塞回程时，液压缸先行卸压，且充液阀的控制口与油箱相通，充液阀可自动开启，使液压缸中的油液大量排回充液油箱。电磁换向阀 DHI-0631/2/A/PE 230AC
