傳統(tǒng)的單閥芯換向閥所組成的液壓系統(tǒng)難以合理解決好以下功能和控制之間存在的矛盾：
（1）液壓系統(tǒng)設計時為提高系統(tǒng)穩(wěn)定性，減少負載變化對速度的影響，要么犧牲部分我們想實現(xiàn)的功能，要么增加額外的液壓元件，如調(diào)速閥、壓力控制閥等，通過增加阻尼，提高系統(tǒng)速度剛度來提高系統(tǒng)的穩(wěn)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(tǒng)的可靠性降低、增加成本,DGMFN-3-X-B2W-41 ,

（2）由于換向結構的特殊性，使得用戶在實現(xiàn)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(jù)不同最終用戶要求設計出相應的功能，這樣會造成生產(chǎn)廠家采購同類、多規(guī)格的液壓控制元件來滿足不同功能要求的需要，不利于產(chǎn)品通用化及產(chǎn)品管理，同時會大大提高產(chǎn)品成本。
（3）由于執(zhí)行機構進出液壓油通過一根閥芯進行控制，單獨控制執(zhí)行機構兩側(cè)壓力是不可能的。因此，出油側(cè)背壓作用于執(zhí)行機構運動的反方向，隨著出油側(cè)背壓升高，為保質(zhì)執(zhí)行機構的運動，必須提高進油側(cè)壓力。這樣會使得液壓系統(tǒng)消耗的功能增加，效率低，發(fā)熱增加。
采用雙閥芯技術的液壓系統(tǒng)，由于執(zhí)行機構進出油側(cè)閥口閥芯位置及控制方式各自獨立，互不影響，這樣通過對兩閥芯控制方式的不同組合，利用軟件編程能很好解決傳統(tǒng)單閥系統(tǒng)不能解決的問題，同時還可以輕易實現(xiàn)傳統(tǒng)液壓系統(tǒng)中難以實現(xiàn)的功能。 C016CA99101299N C016CA99101299N10
