    电液换向阀是电磁换向阀和液控换向阀的组合，它是用电磁换向阀控制液控换向阀的动作，变换流体流动方向的控制阀。
电液换向阀和液控换向阀主要用在流量**过电磁换向阀正常工作允许范围的液压系统中，对执行元件的动作进行控制，或对油液的流动方向进行控制。
说明事项
  1. 产品可任意安装，**考虑水平位置。
  2. 液压系统所用介质必须过滤，过滤精度至少20μm。
  3. 固定螺钉请按样本中所列参数选用。
  4. 与阀连接的表面，粗糙度要求Ra0.8，平面度要求0.01/100mm
     
    工作原理：当两个电磁阀线圈通电时，平衡孔回路关闭，泄流孔回路打开，活塞上腔泄压，活塞上行，阀门打开。反之，活塞下行，阀门关闭。在阀门开启和关闭过程中，可将流量（流速）信号及阀塞位置信号传送给计算机，经过计算机处理后发出相应的指令，控制两个电磁导阀的通、断电状态，使活塞的上下腔的液压差产生变化，从而将活塞控制在所需的开启高度上，实现对管道介质流量的控制。

换向阀是具有两种以**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。
可分为手动换向阀、电磁换向阀、电液换向阀等。
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。
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较为常用。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。

电磁阀（Electromagnetic valve）是用电磁控制的工业设备，是用来控制流体的自动化基础元件，属于执行器，并不限于液压、气动。用在工业控制系统中调整介质的方向、流量、速度和其他的参数。电磁阀可以配合不同的电路来实现预期的控制，而控制的精度和灵活性都能够保证。电磁阀有很多种，不同的电磁阀在控制系统的不同位置发挥作用，较常用的是单向阀、安全阀、方向控制阀、速度调节阀等。
电磁阀里有密闭的腔，在不同位置开有通孔，每个孔连接不同的油管，腔中间是活塞，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来开启或关闭不同的排油孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。
