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）。

对中弹簧控制阀芯
可选阶跃补偿
电磁阀应用十分广泛，而使用时情况却千差万别，增强通用性能降低制造、购销、存贮、安装、维护的成本，近年来这方面迈出了大步。
(1)响应时间可调
给出电信号到阀芯动作完成的时间称为响应时间。不同场合希望开关速度不同，有四种组合：快开快关----用于快速反应系统;快开慢关----用于防止水锤;慢开快关---用于缓启急断; 慢开慢关一一用于平稳过渡。ZDF 多功能电磁阀可方使地调整于任一状态，应用十分灵活。
(2)扩展介质适用范固。
电磁阀与其它自控阀不同在于介质粘度适用范围较窄，所以空气、水、蒸汽、油等介质对于先导型电磁阀其结构参数是不同的;一般地说是不能通用的。而ZDF多功能电磁阀只用一颗小螺钉，却做到了气、水、油的通用，而且还使油的粘度适用范围大大加宽，深受欢迎。
(3)开度可调与于动兼窑
电磁阀在使用时常常还希望它兼具手动功能，作为停电或故障时备用。
一般手动装置只能手动开阀或手动关阀，二者齐备的称完全手动。手动装置还能对阀门开度进行预置，一般手动只能对阀的非常大或较小开度进行预置，而完全手动能分别对非常大或较小开度进行预置。ZDF多功能电磁阀属完全手动类。其它型号电磁阀根据需要可带简单的一般手动装置。
