液壓傳動中用來控制液體壓力﹑流量和方向的元件。其中控制壓力的稱為壓力控制閥,，控制流量的稱為流量控制閥,，控制通﹑斷和流向的稱為方向控制閥。

　　壓力控制閥：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)在達到調(diào)定壓力時保持恒定狀態(tài),。用於過載保護的溢流閥稱為安全閥。當系統(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,。（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：能使一個執(zhí)行元件（如液壓缸﹑液壓馬達等）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運動,，同時通過順序閥的進油口作用在面積A 上,，當液壓缸1運動*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,，閥芯上升使進油口與出油口相通，使液壓缸2運動。Rexroth泵A10VSO71DR/31R-PPA12N00

　　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行調(diào)節(jié),，從而控制執(zhí)行元件的運動速度,。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動均勻性要求不高的執(zhí)行元件的運動速度基本上保持穩(wěn)定。（2）調(diào)速閥：在載荷壓力變化時能保持節(jié)流閥的進出口壓差為定值,。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)行元件的運動速度穩(wěn)定。（3）分流閥：不論載荷大小,，能使同一油源的兩個執(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。

　　方向控制閥：按用途分為單向閥和換向閥,。單向閥：只允許流體在管道中單向接通,，反向即切斷。換向閥：改變不同管路間的通﹑斷關(guān)系﹑根據(jù)閥芯在閥體中的工作位置數(shù)分兩位﹑三位等,；根據(jù)所控制的通道數(shù)分兩通﹑三通﹑四通﹑五通等,；根據(jù)閥芯驅(qū)動方式分手動﹑機動﹑電動﹑液動等。圖2為三位四通換向閥的工作原理,。P 為供油口,，O 為回油口，A ﹑B 是通向執(zhí)行元件的輸出口,。當閥芯處於中位時,，全部油口切斷，執(zhí)行元件不動,；當閥芯移到右位時,，P 與A 通，B 與O 通,；當閥芯移到左位時,，P 與B 通，A 與O 通,。這樣,，執(zhí)行元件就能作正﹑反向運動。
