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(jī)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(dāng)閥芯處於中位時，全部油口切斷，執(zhí)行元件不動；當(dāng)閥芯移到右位時，P 與A 通，B 與O 通；當(dāng)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(yùn)動。
