伺服阀与比例阀的区别
伺服阀与比例阀之间的差别并没有严格的规定，因为比例阀的性能越来越好，逐渐向伺服阀靠近，所以近些年出现了比例伺服阀。
比例阀和伺服阀的区别主要体现在以下几点：
1.驱动装置不同。比例阀的驱动装置是比例电磁铁；伺服阀的驱动装置是力马达或力矩马达；
2.性能参数不同。滞环、中位死区、频宽、过滤精度等特性不同，因此应用场合不同，伺服阀和伺服比例阀主要应用在闭环控制系统，其它结构的比例阀主要应用在开环控系统及闭环速度控制系统；
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，需要经过滤才行，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）。
5.阀的额定压降不同。
而比例伺服阀性能介于伺服阀和比例阀之间。
比例换向阀属于比例阀的一种，用来控制流量和流向。
