四通换向球阀为X形垂直通道的球阀，它的特点是球体的两条通道为X形布置，四个通道口径均布于球体赤道圆周截面上，当球体沿顺时针旋转90时，能使相邻的两个通道实现两两互通。
Four-way direction changeable ball value is a king of ball value with X-pattern vertical bore.lt’sfeature is,the ball valves two bores are arranged to be X-pattem and its forbears are connected toeach other two of adjacant bores can be connected to each other.
