一个额外的端口，有时加入到一个四通阀，使其成为一个五端口四通阀！四通阀与一个额外的端口通常被用来提供双压力，这意味着该阀可以根据哪些应用需要采用两种压力和备用两者中的一个！可替代地，阀可以用其他的端口作为辅助排气口。弹簧偏置这种类型的气动阀的分类是指在空气流动方向被切换的方式.例如，在一个双向定向阀，该阀可以是开放的（空气流使能）或关闭（防止空气流动）！为了使每个端口假设打开或关闭位置时，致动器移动的滑阀到位。
若气动阀埋设较深，操作机构及显示盘离地面距离≥5m时，应设有加长杆设施，且固定稳牢，以便人们从地面上观察及操作!也就是说，管网中的阀门启闭操作，不宜下井作业！气动阀注意事项气动阀门属于现场仪表，要求环境温度应在-25～60℃范围，相对湿度≤95%！如果是装置在露天或高温场合，应采取防水、降温措施.在有震源的地方要远离振源或增加防振措施！气动阀门一般应垂直装置，特殊情况下可以倾斜，如倾斜角度很大或者阀本身自重太大时对阀应增加支承件保护！

为了便于一个人的启闭操作，在管道工压状况下，启闭力矩宜为240N-m.气动阀启闭操作端应为方榫，且尺寸标准化，并面向地面，以便人们从地面上可直接操作！带阀门不适用于地下管网。气动阀启闭程度的显示盘a、气动阀启闭程度的刻度线，应铸造在变速箱盖上或转换方向后的显示盘的外壳上，一律面向地面，刻度线刷上荧光粉，以示醒目;b、指示盘针的材质在管理较好的情况下可用不锈钢板，否则为刷漆的钢板，切勿使用铝皮制作;c、指示盘针醒目，固定牢靠，一旦启闭调节准确后，应以铆钉锁定！
