　 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。

　　 无杆腔流量控制是通过检测连接到无杆腔侧阀前后两侧的压差，再根据所需流入或流出流量的多少，计算出阀芯开口大小；有杆腔侧采用压力控制，使该侧维持一个低值的压力，使得更加节能、高效。

　　 由于我们在无杆腔采用了流量控制，因此原控制系统中所用的平衡阀可用一个液控单向阀来代替。这样可消除因平衡阀所带来的系统不稳定，从而提高系统稳定性。 

（2）负载方向在工作过程中发生改变 

　　 在这种情况下，采取“进油侧压力控制，出油侧流量控制”，在液压缸有杆腔侧用压力控制，无杆腔侧有流量控制。
