比例閥采用閥芯+閥體結(jié)構(gòu)。伺服閥和伺服比例閥主要應(yīng)用在閉環(huán)控制系統(tǒng)，比例閥的驅(qū)鑫裝置是比例電磁鐵。
伺服閥的驅(qū)鑫裝置是力馬達(dá)或力矩馬達(dá).閥體兼作閥套。
驅(qū)鑫裝置不同.所以近些年出現(xiàn)了比例伺服閥。
比例閥一般zui高幾十Hz，伺服閥中位沒有死區(qū)，伺服閥對液壓油液的要求更高.性能參數(shù)不同；否則容易堵塞，
用來控制流量和流向，比例閥要求低一些.比例閥有中位死區(qū)；
比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點：
逐漸向伺服閥靠近，
比例換向閥屬于比例閥的一種，滯環(huán)、中位死區(qū)、頻寬、過濾精度等特性不同.閥的額定壓降不同；比例換向閥具有與普通換向閥相似的中位機(jī)能，
而比例伺服閥性能介于伺服閥和比例閥之間，因此應(yīng)用場合不同，伺服閥和伺服比例閥采用閥芯+閥套的結(jié)構(gòu)。中位機(jī)能種類不同.其它結(jié)構(gòu)的比例閥主要應(yīng)用在開環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng)；因為比例閥的性能越來越好；2伺服閥的頻響（響應(yīng)頻率）更高。閥芯結(jié)構(gòu)及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴(yán)格的規(guī)定。
，可以高達(dá)200Hz左右，需要精過濾才行，而伺服閥中位機(jī)能只有O型（Rexroth產(chǎn)品的E型）。
