比例阀和伺服阀的差异首要体现在以下几点：1.驱动设备不同。比例阀的驱动设备是比例电磁铁;伺服阀的驱动设备是力马达或力矩马达;2.功用参数不同。滞环、中位死区、频宽、过滤精度等特性不同，因而使用场合不同，伺服阀和伺服比例阀首要使用在闭环控制体系，其它结构的比例阀首要使用在开环控体系及闭环速度控制体系;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(照应频率)更高，能够高达200Hz左右，比例阀一般几十Hz;2.3 伺服阀对液压油液的要求更高，需求精过滤才行，不然简略阻塞，比例阀要求低一些;3.阀芯结构及加工精度不同。比例阀选用阀芯+阀体结构，阀体兼作阀套。伺服阀和伺服比例阀选用阀芯+阀套的结构。4.中位机能种类不同。比例换向阀具有与一般换向阀相似的中位机能，而伺服阀中位机能只要O型(Rexroth产品的E型)。5.阀的额定压降不同。而比例伺服阀功用介于伺服阀和比例阀之间。比例换向阀归于比例阀的一种，用来控制流量和流向。
