傳統換向閥的進出油口控制通過一根閥芯來進行，兩油口的開口對應關系早在閥芯設計加工時已確定，在使用過程中不可能修改，從而使得通過兩油口的流量或壓力不能進行獨立控制，互不影響。磁力泵

隨著微處理控制器、傳感器元件成本的下降，控制技術的不斷完善，使得雙閥芯控制技術在工程機械領域得以應用。英國Utronics公司利用自己的技術及專利優勢研制出雙閥芯多路換向閥，已廣泛應用于JCB、Deere、DAWOO、CASE等公司的挖掘機、裝載機及挖掘裝載機等產品上。為適應中國工程機械產品對液壓系統功能要求。穩定性以及自動化控制程度的不斷提高，Utronics公司產品適時進入中國市場，現已初步完成廈工（5t）裝載機、詹陽（8t）挖掘機樣機調試并進入試驗階段。?

，要么增加額外的液壓元件，如調速閥、壓力控制閥等，通過增加阻尼，提高系統速度剛度來提高系統的穩定性。但是這樣元件的增加又會降低效率，浪費能源；還會使得整個系統的可靠性降低、增加成本。?

　　?（2）由于換向結構的特殊性，使得用戶在實現某一功能時必須購買相應的液壓元件，再加上工程機械廠家會根據不同最終用戶要求設計出相應的功能，這樣會造成生產廠家采購同類、多規格的液壓控制元件來滿足不同功能要求的需要，不利于產品通用化及產品管理，同時會大大提高產品成本。?

　　?（3）由于執行機構進出液壓油通過一根閥芯進行控制，單獨控制執行機構兩側壓力是不可能的。因此，出油側背壓作用于執行機構運動的反方向，隨著出油側背壓升高，為保質執行機構的運動，必須提高進油側壓力。這樣會使得液壓系統消耗的功能增加，效率低，發熱增加。?
