比例阀采用阀芯+阀体结构。伺服阀和伺服比例阀主要应用在闭环控制系统，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.阀体兼作阀套。
驱动装置不同.所以近些年出现了比例伺服阀。
比例阀一般较高几十Hz，伺服阀中位没有死区，伺服阀对液压油液的要求更高.性能参数不同；否则容易堵塞，
用来控制流量和流向，比例阀要求低一些.比例阀有中位死区；
比例阀和伺服阀的区别主要体现在以下几点：
逐渐向伺服阀靠近，
比例换向阀属于比例阀的一种，滞环、中位死区、频宽、过滤精度等特性不同.阀的额定压降不同；比例换向阀具有与普通换向阀相似的中位机能，
而比例伺服阀性能介于伺服阀和比例阀之间，因此应用场合不同，伺服阀和伺服比例阀采用阀芯+阀套的结构。中位机能种类不同.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；因为比例阀的性能越来越好；2伺服阀的频响（响应频率）更高。阀芯结构及加工精度不同.伺服阀与比例阀之间的差别并没有严格的规定。
，可以高达200Hz左右，需要精过滤才行，而伺服阀中位机能只有O型（Rexroth产品的E型）。

 溢流阀是一种液压压力控制阀。在液压设备中主要起定压溢流作用，稳压，系统卸荷和安全保护作用。 　定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力加大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。 
稳压作用：溢流阀串联在回油路上，溢流阀产生背压运动部件平稳性增加。 　　
系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。 　　
安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的较限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统较高工作压力高10%～20%）。 　　
实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压（串在回油路上）。 　　
溢流阀一般有两种结构：1、直动型溢流阀 。2、先导型溢流阀。 　　
对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。DBW20B2-5X/3506EG24N9K4
