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。
2、双阀芯换向阀的两种基本控制策略

由于双阀芯换向两油口控制的灵活性，两油口可分别采取流量控制、压力控制或流量压力控制。正面介绍两种简单的控制策略。
（1）负载方向在整个工作过程中保持不变

我们知道，对于汽车起重机、挖掘机、装载机等而言，其液压缸在整个工作过程中负载方向始终维持不变。下面以起重机变幅液压缸为例来探讨双阀芯的控制策略。
起重机变幅缸在工作过程中其受力，负载方向始终保持不变，因此我们可以采取液压缸有杆控用压力控制、无杆腔用流量控制的控制策略。
