换向阀是具有两种以上流动形式和两个以上油口的方向控制阀。是实现液压油流的沟通、切断和换向，以及压力卸载和顺序动作控制的阀门。靠阀芯与阀体的相对运动的方向控制阀。有转阀式和滑阀式两种。按阀芯在阀体内停留的工作位 置数分为二位、三位等;按与阀体相连的油路数分为二通、三通、四通和六通等;操作阀芯运动的方式有 手动、机动、电动、液动、电液等型式。
换向阀又称克里斯阀，阀门的一种，具有多向可调的通道，可适时改变流体流向。可分为手动换向阀、电磁换向阀、电液换向阀等。
工作时借着阀外的驱动传动机构转动驱动轴，带动摇拐臂，启动阀板，使工作流体时而从左入口通向阀的下部出口，时而从右入口变换通向下部出口，实现了周期变换流向的目的。
这种变换阀在石油、化工生产中有着广泛的应用，在合成氨造气系统中为常用。此外，换向阀还可作成阀瓣式的结构，多用于较小流量的场合。工作时只需转动手轮通过阀瓣来变换工作流体的流向。
