液压阀的正确选用
对任何液压系统而言，正确选用液压阀，将是使得液压系统设计合理，性能优良，安装简便，维护容易，同时保证系统正常工作的重要条件。下面从几个方面来简述如何合理选用液压阀。

1．选择的一般原则

首先根据系统的功能要求，确定液压阀的类型。应尽量选择标准系列的通用产品。根据实际安装情况，选择不同的连接方式，例如管式或板式连接等。然后，根据系统设计的较高工作压力选择液压阀的额定压力，根据通过液压阀的较大流量选择液压阀的流量规格。如溢流阀应按液压泵的较大流量选取；流量阀应按回路控制的流量范围选取，其较小稳定流量应小于调速范围所要求的较小稳定流量。
2．液压阀安装方式的选择

液压阀的安装方式对液压装置的结构形式有决定性的影响，因此要根据具体情况来选择合适的安装方式。一般来说，在选择液压阀安装方式的时候，应根据所选择的液压阀的规格大小、系统的复杂程度及布置特点来定。上面所介绍的几种安装方式，各有特点。螺纹连接型，适合系统较简单，元件数目较少，安装位置比较宽敞的场合。板式连接型，适合系统较复杂，元件数目较多，安装位置比较紧凑的场合。连接板内可以钻孔以沟通油路，将多个液压元件安装在这连接板上，可减少液压阀之间的连接管道，减少泄漏点，使得安装、维护更方便。法兰连接型一般用于大口径的阀。
3．液压阀额定压力的选择

液压阀的额定压力是液压阀的基本性能参数，标志着液压阀承压能力的大小，是指液压阀在额定工作状态下的名义压力。液压阀额定压力的选择，应根据液压系统设计的工作压力选择相应压力级的液压阀。一般来说，应使液压阀上标明的额定压力值适当大于系统的工作压力。
