方向控制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。
單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動,或者用于氣動系統(tǒng)中防止壓縮空氣逆向流動。
單向閥Check Valve
單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動,或者用于氣動系統(tǒng)中防止壓縮空氣逆向流動。
單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥，它與單向閥相同，用以防止油液反向流動。但在液壓回路中需要油流反向流動時又可利用控制油壓，打開單向閥，使油流在兩個方向都可流動。液控單向閥采用錐形閥芯，因此密封性能好。在要求封閉油路時，可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無背壓的油路中可用內(nèi)泄式；否則需用外泄式，以降低控制油壓力。

單向閥是流體只能沿一個方向流通，另一方向不能通過的閥。單向閥就是止回閥 止回閥只供防止各類管路或設(shè)備上流體介質(zhì)逆流的單向啟閉閥。 止回閥用途廣泛，有很多種類，下面說的是供水和熱力常用的止回閥： 1、彈簧式：液體由下而上，依靠壓力頂起彈簧控制的閥瓣，壓力消失后，彈簧力將閥瓣壓下，封閉液體倒流。常用于通徑較小的止回閥。 2、重力式：和彈簧式相似，依靠閥瓣的自身重力封閉，防止倒流。 3、旋啟式：液體在閥體內(nèi)直通，依靠壓力頂開一側(cè)的旋轉(zhuǎn)閥瓣，壓力失去后，閥瓣依靠自重回位，反向的液體壓力封閉閥瓣。 其它的單向閥（止回閥），如排污的止回閥，人防的防爆閥和液體使用的止回閥的原理是大同小異
