2.1 伺服阀中位没有死区，比例阀有中位死区；
2.2 伺服阀的频响（响应频率）更高，可以高达200Hz左右，比例阀一般最高几十Hz；
2.3 伺服阀对液压油液的要求更高，需要精过滤才行，否则容易堵塞，比例阀要求低一些；
3.阀芯结构及加工精度不同。比例阀采用阀芯+阀体结构，阀体兼作阀套。伺服阀和伺服比例阀采用阀芯+阀套的结构。
4.中位机能种类不同。比例换向阀具有与普通换向阀相似的中位机能，而伺服阀中位机能只有O型（Rexroth产品的E型）。

液控伺服阀是在伺服系统中将电信号输入转换为功率较大的压力或流量压力信号输出的执行元件。它是一种电液转换和功率放大元件。伺服阀的灵敏度高，快速性好，能将很小的电信号（例如10毫安）转换成很大的液压功率（如几十匹马力以上），可以驱动多种类型的负载。过去人们曾把喷嘴档板阀、射流管或滑阀伺服马达等液压放大装置都列入伺服阀范围内。20世纪70年代以来，伺服阀一般仅指电液伺服阀。
