比例伺服閥由永磁力矩馬達(dá)、噴嘴、檔板、閥芯、閥套和控制腔組成(見圖)。當(dāng)輸入線圈 通入電流時(shí)，檔板向右移動(dòng)，使右邊噴嘴的節(jié)流作用加強(qiáng)，流量減少，右側(cè)背壓上升；同 時(shí)使左邊噴嘴節(jié)流作用減小，流量增加，左側(cè)背壓下降。閥芯兩端的作用力失去平衡, 閥 芯遂向左移動(dòng)。高壓油從S流向C2，送到負(fù)載。負(fù)載回油通過(guò) C1流過(guò)回油口，進(jìn)入油箱。 閥芯的位移量與力矩馬達(dá)的輸入電流成正比，作用在閥芯上的液壓力與彈簧力相平衡，因 此在平衡狀態(tài)下力矩馬達(dá)的差動(dòng)電流與閥芯的位移成正比。如果輸入的電流反向，則流量 也反向。

 

比例電磁鐵的性能指標(biāo)主要包括適用電壓（電流）、推（拉）力和行程等。
根據(jù)電壓可以分為12V直流，24V直流，110V交流，220V交流等。NG6閥用電磁鐵推拉力一般為20-
70N，行程在 3-7mm之間。當(dāng)懷疑某電磁閥卡滯或線圈燒毀時(shí)，可以將電磁閥反過(guò)來(lái)，看其行程是否在上述范圍之內(nèi)。
電磁鐵的外特性主要表現(xiàn)為電阻。較常見的24V NG6電磁閥線圈阻值一般在16-26Ω之間，24V插裝
閥線圈阻值一般在20-38Ω之間，24V比例閥線圈阻值一般在21-26Ω。理論上，電磁吸力與電流的平方成正比，所以12V線圈阻值一般為對(duì)應(yīng)24V線圈的1/4左右。

電液換向閥由電磁換向閥和液動(dòng)換向閥組成，其中電磁換向閥起先導(dǎo)作用，即用來(lái)改變液動(dòng)換向閥控制壓力油的方向;液動(dòng)換向閥作為主閥，其工作位置由電磁換向閥的工作位置相應(yīng)確定。電液換向閥根據(jù)控制油和回油方式分為:內(nèi)控內(nèi)泄式、內(nèi)控外泄式、外控內(nèi)泄式、外控外泄式四種。對(duì)于外控式閥，由于控制油是從電液換向閥之外的油路單獨(dú)引入的，在使用時(shí)，無(wú)論內(nèi)泄還是外泄，均不存在什么問題。對(duì)以內(nèi)控方式供油的電液動(dòng)換向閥，由于先導(dǎo)閥的供液口與主閥的P口是溝通的，若在中間位置是使泵卸荷的狀態(tài)，如M、H、K等中位機(jī)能，在中位時(shí)主油路不能為控制油路提供主閥芯換向所必須的控制壓力
