壓力控制按用途分為溢流閥﹑減壓閥和順序閥。⑴溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時保持恒定狀態(tài)。用於過載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時，閥口會打開而溢流，以保證系統(tǒng)的安全。⑵減壓閥：能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。減壓閥按它所控制的壓力功能不同，又可分為定值減壓閥（輸出壓力為恒定值）﹑定差減壓閥（輸入與輸出壓力差為定值）和定比減壓閥（輸入與輸出壓力間保持一定的比例）。⑶順序閥：能使一個執(zhí)行元件（如液壓缸﹑液壓馬達(dá)等）動作以后，再按順序使其他執(zhí)行元件動作。油泵產(chǎn)生的壓力先推動液壓缸1運(yùn)動，同時通過順序閥的進(jìn)油口作用在面積A 上，當(dāng)液壓缸1運(yùn)動完全成后，壓力升高，作用在面積A 的向上推力大於彈簧的調(diào)定值后，閥芯上升使進(jìn)油口與出油口相通，使液壓缸2運(yùn)動。

主要用于故障時以及防止手動操作時超過極限位置保護(hù)。角行程電動執(zhí)行機(jī)構(gòu)的機(jī)械限位采用內(nèi)置扇形渦輪限位結(jié)構(gòu)，外形體積小，限位可靠；直行程電動執(zhí)行機(jī)構(gòu)的機(jī)械限位采用內(nèi)置擋塊型限位結(jié)構(gòu)，可十分有效地保護(hù)閥座、閥桿、閥芯。
位置定位器實(shí)質(zhì)上是一個將控制信號與位置反饋信號進(jìn)行比較并放大以控制電動機(jī)開停和旋轉(zhuǎn)方向的多功能大功率放大板，它與執(zhí)行機(jī)構(gòu)的動力部件相連以控制執(zhí)行機(jī)構(gòu)按系統(tǒng)規(guī)定的狀態(tài)工作。位置定位器主要由比較、邏輯保護(hù)、放大驅(qū)動及功率放大等電路組成?？刂茊蜗嚯妱訖C(jī)的位置定位器功率放大部分主要由光電禍合過零觸發(fā)固態(tài)繼電器（無觸點(diǎn)電子開關(guān)）構(gòu)成。其主體部分示意如圖4所示。需要注意的是“手動一自動”轉(zhuǎn)換開關(guān)，該開關(guān)的作用是在沒有外加信號時，與手動調(diào)整電位器P1配合使用，以便觀察或調(diào)試執(zhí)行機(jī)構(gòu)。用后一定要將其撥回“自動”位世，以免影響投人系統(tǒng)自動控制。
