电液比例控制阀?作用：连续或按比例地随输入电气信号的变化而调节和控制液流压力、方向和流量 分类 结构简单化，电液伺服阀准确度降低，电磁比+普通的液压阀外观与一般的电磁铁相同，但吸力大∝I 按控制参数：比例压力阀、比例流量阀、比例方向阀 特点：既具有结构简单，通用性强的特点，又具有伺服阀能远程、连续操纵优点，故而又称“廉价伺服阀” 比例溢流阀：比例电磁铁+直动溢流阀主体 比例溢流阀工作原理：输入一I，产生一电磁力，作用于阀芯上，得到一控制压力，其p∝I，I变化，p也变化。
比例溢流阀特点 1比例电磁铁与其他压力阀组合，可简单组成比例溢流阀、比例顺序阀、比例减压阀 2用一个比例阀可实现多级压力控制，简单化油路，如：三级调压回路举例 比例换向阀组成：比例电磁铁替代普通的电磁换向阀中的普通电磁铁即可。
工作原理：输入一I，得到一个运动方向，并且还可改变输出流量的大小；改变电流信号极性，即可改变运动方向 特点 1∵换向阀芯上有一个三角槽 ∴阀芯运动时，其通流面积变化 故?液流方向变化时，流量也会变化 2在大流量情况下，应采用先导式比例方向阀。
也可做成比例多路阀 比例调速阀组成:比例电磁铁可以代替调速阀中的调节螺帽 比例调速阀工作原理：输入一个I，节流阀阀口、流量、q∝I 比例调速阀特点 1∵有定差减压阀保证△p节=c，∴q不随F变化而变化，qV=c。
2用一个阀只须改变I，便可得到多级速度，油路简单如：转塔进给系统 电液数字阀的开发：20世纪80年代初开发的可用计算机实现电液系统控制的新 方法：增量式数字阀 电液数字阀分类:数字流量阀、数字压力阀、数字方向流量阀 举例：增量式数字流量阀 增量式数字流量阀组成：步进电动机、滚珠丝杠、阀芯、阀套、阀杆、传感器等 工作原理：计算机发出信号后，步进电机转动，通过滚丝杠转化为轴向位移，带动节流阀阀心移动，首先打开非全周节流口，流量较小，而后打开全周节流口，流量较大，可达3600l/min。
特点 1阀芯、阀套、阀杆的相对热膨胀?取得温度补偿，维持流量恒定 2该阀无反馈功能，但装有零位移传感器，每个控制终了，阀芯都可在它控制下回到零位，重复精度较高 90-L-075-KP-1-BC-80-S-3-S1-D-00-GBA-42-42-24 90L075KP1BC80S3S1D00GBA424224 90-L-075-KP-1-BC-80-S-3-S1-D-03-GBA-35-35-24
