1.流体阻力小，球阀是所有阀类中流体阻力小的一种，即使是缩径球阀，其流体阻力也相当小。

    2.开关迅速、方便，只要阀杆转动90°，球阀就完成了全开或全关动作，很容易实现快速启闭。  
    3.阀座密封性能好。大多数球阀的密封圈都采用聚四乙烯等弹性材料制造，软密封结构易于确保启封，而且球阀的密封力随着介质压力的增大而增大。
    4.阀杆密封稳定。球阀启闭时阀杆只作旋转运动而不作升降运动，阀杆的填料密封不易破坏，且阀杆倒密封的密封力随着介质压力的增大而增大。
    5.由于聚四氟乙烯等材料具有良好的自润滑性，与球体的摩擦损小，故球阀的使用寿命长。
    6.可配置气动、电动、液动等多种驱动机构，实现远距离控制和自动化操作。
    7.阀体内通道平整光滑，可以输送粘性流体、浆液以及固体颗粒。
    8.安装简便，能以任意方向安装于管道中的任意部位。
