传统的单阀芯换向阀所组成的液压系统难以合理解决好以下功能和控制之间存在的矛盾：
（1）液压系统设计时为提高系统稳定性，减少负载变化对速度的影响，要么牺牲部分我们想实现的功能，要么增加额外的液压元件，如调速阀、压力控制阀等，通过增加阻尼，提高系统速度刚度来提高系统的稳定性。但是这样元件的增加又会降低效率，浪费能源；还会使得整个系统的可靠性降低、增加成本,DGMFN-3-X-B2W-41 ,

（2）由于换向结构的特殊性，使得用户在实现某一功能时必须购买相应的液压元件，再加上工程机械厂家会根据不同最终用户要求设计出相应的功能，这样会造成生产厂家采购同类、多规格的液压控制元件来满足不同功能要求的需要，不利于产品通用化及产品管理，同时会大大提高产品成本。
（3）由于执行机构进出液压油通过一根阀芯进行控制，单独控制执行机构两侧压力是不可能的。因此，出油侧背压作用于执行机构运动的反方向，随着出油侧背压升高，为保质执行机构的运动，必须提高进油侧压力。这样会使得液压系统消耗的功能增加，效率低，发热增加。
采用双阀芯技术的液压系统，由于执行机构进出油侧阀口阀芯位置及控制方式各自独立，互不影响，这样通过对两阀芯控制方式的不同组合，利用软件编程能很好解决传统单阀系统不能解决的问题，同时还可以轻易实现传统液压系统中难以实现的功能。 C016CA99101299N C016CA99101299N10
