美國SOR開關6NN-K2-N4-F1A     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、斷關系、根據閥芯在閥體中的工作位置數分兩位、三位等；根據所控制的通道數分兩通C4V03-5303-B1，016-88955-0 現貨

、三通、四通、五通等；根據閥芯驅動方式分手動、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 是通向執行元件的輸出口。當閥芯處於中位時，全部油口切斷，執行元件不動；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，執行元件就能作正、反向運動。 60年代后期，在上述幾種液壓控制閥的基礎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變化。電液比例控制閥按作用不同，相應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。
