一般說來，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開環(huán)控制；其次比例閥類型要多，有比例壓力、流量控制閥等，控制比伺服要靈活一些。從他們內(nèi)部結(jié)構(gòu)看，伺服閥多是零遮蓋，比例閥則有一定的死區(qū)，控制精度要低，響應(yīng)要慢。但從發(fā)展趨勢(shì)看，特別在比例方向流量控制閥和伺服閥方面，兩者性能差別逐漸在縮小，另外比例閥的成本比伺服閥要低許多，抗污染能力也強(qiáng)！

防滯伺服活門
該伺服閥屬于兩級(jí)閥，第一級(jí)為噴嘴檔板式，由控制信號(hào)控制其出口壓力，第二級(jí)為滑閥式，執(zhí)行控制級(jí)至剎車缸的壓力。當(dāng)無信號(hào)作用時(shí)， 由於壓力噴嘴出口油壓力的作用，使伺服閥擋板靠在回油噴嘴上，此時(shí)壓力口的油壓作用在滑閥閥芯上，使剎車口同計(jì)量油口直接連通，剎車口壓力同飛行員控制的計(jì)量油壓相等，當(dāng)機(jī)輪角速度檢測(cè)到滑行速度同基準(zhǔn)滑行速度有偏差時(shí)，力矩馬達(dá)接收到偏差電信號(hào)，此時(shí)力矩馬達(dá)驅(qū)動(dòng)檔板向壓力噴嘴偏轉(zhuǎn)，使作用在閥芯上端油壓下降，在閥芯下端油壓作用下，閥芯上移，關(guān)小計(jì)量壓力油口，這將導(dǎo)致控制口壓力降低，控制口壓力降低到某一值時(shí)，就有對(duì)應(yīng)的制動(dòng)壓力

2）要是開啟的時(shí)間短或開和關(guān)的時(shí)間不多時(shí)，則選常閉型；
3）但是有些用于安全保護(hù)的工況，如爐、窯火焰監(jiān)測(cè)，則不能選常開的，應(yīng)選可長期通電型。
6、根據(jù)環(huán)境要求選擇輔助功能：防爆、止回、手動(dòng)、防水霧、水淋、潛水。
