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、***。
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。 4WRE6W1-08-2X/G24K4/V

如负载方向不变，由于出油侧采取了流量控制，我们可将双向平衡阀用液控单向阀来替换，从而提高系统的稳定性。进油侧用压力控制器来维持一个较低的参考压力，一方面提高系统效率，另一方面使系统不发生气穴
