            球阀是由旋塞阀演变而来。它具有相同的旋转90度提动作， 电动蝶阀不同的是旋塞体是球体，有圆形通孔或通道通过其轴线。电动闸阀球面和通道口的比例应该是这样的，即当球旋转90度时，在进、出口处应全部呈现球面，从而截断流动。 球阀只需要用旋转90度的操作和很小的转动力矩就能关闭严密。电动截止阀完全平等的阀体内腔为介质提供了阻力很小、直通的流道。通常认为电动球阀球阀最适宜直接做开闭使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用。电动调节阀球阀的主要特点是本身结构紧凑，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等。球阀阀体可以是整体的，也可以是组合式的。

             Evolved from the plug valve. It has the same movement raised 90 degrees, is the cock body is different sphere, thereMUD VALVES are circular holes or channels through its axis. The ratio of the sphere and the openings should be such that when the ball is rotated 90 degrees, the import and export office should be fully SAFETY VALVES present sphere, thus cutting off the flow. Only need 90 degrees ball valve operation and a small rotation torque can be closed tightly. Full equality for the medium body cavity to provide a little resistance, through the flow channel. Generally considered the most suitable valve opening and closing used directlyMULTI-FUNCTIONAL WATER PUMP CONTROL VALVE to do, but the recent development has been designed to make it a throttle valve and flow control purposes. The main characteristics of ball valve itself compact,REDUCING VALVES easy operation and maintenance for water, solvents, acids, and natural gas general working media, but also PLUG VALVESto poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene . Ball valve can be integral, it can be modular.
