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)，閥口會打開而溢流，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(如液壓缸、液壓馬達(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)。流量控制閥利用調(diào)節(jié)閥芯和閥體間的節(jié)流口面積和它所產(chǎn)生的局部阻力對流量進(jìn)行調(diào)節(jié)，從而控制執(zhí)行元件的運(yùn)動(dòng)速度。
流量控制閥
按用途分為 5種。(1)節(jié)流閥：在調(diào)定節(jié)流口面積后，能使載荷壓力變化不大和運(yùn)動(dòng)均勻性要求不高的執(zhí)行元件的運(yùn)動(dòng)速度基本上保持穩(wěn)定。(2)調(diào)速閥：在載荷壓力變化時(shí)能保持節(jié)流閥的進(jìn)出口壓差為定值。

這樣，在節(jié)流口面積調(diào)定以后，不論載荷壓力如何變化，調(diào)速閥都能保持通過節(jié)流閥的流量不變，從而使執(zhí)行元件的運(yùn)動(dòng)速度穩(wěn)定。(3)分流閥：不論載荷大小，能使同一油源的兩個(gè)執(zhí)行元件得到相等流量的為等量分流閥或同步閥；得到按比例分配流量的為比例分流閥。(4)集流閥：作用與分流閥相反，使流入集流閥的流量按比例分配。(5)分流集流閥：兼具分流閥和集流閥兩種功能。

通；當(dāng)閥芯移到左位時(shí)，P 與B 通，A 與O 通。這樣，執(zhí)行元件就能作正、反向運(yùn)動(dòng)。 60年代后期，在上述幾種液壓控制閥的基礎(chǔ)上又研制出電液比例控制閥。它的輸出量(壓力、流量)能隨輸入的電信號連續(xù)變化。電液比例控制閥按作用不同，相應(yīng)地分為電液比例壓力控制閥、電液比例流量控制閥和電液比例方向控制閥等。
