液壓閥是一種用壓力油操作的自動(dòng)化元件，它受配壓閥壓力油的控制，通常與電磁配壓閥組合使用，可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。常用于夾緊、控制、潤(rùn)滑等油路。有直動(dòng)型與先導(dǎo)型之分，多用先導(dǎo)型。
按用途分為溢流閥﹑減壓閥和順序閥。
(1)溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過(guò)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(shí)，閥口會(huì)打開(kāi)而溢流，以保證系統(tǒng)的安全。(
2)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)。
(3)順序閥：能使一個(gè)執(zhí)行元件(如液壓閥、達(dá)等)動(dòng)作以后，再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力先推動(dòng)液壓缸1運(yùn)動(dòng)，同時(shí)通過(guò)順序閥的進(jìn)油口作用在面積a 上，當(dāng)液壓缸1運(yùn)動(dòng)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(dòng)。
