四通換向球閥為X形垂直通道的球閥，它的特點是球體的兩條通道為X形布置，四個通道口徑均布于球體赤道圓周截面上，當球體沿順時針旋轉90時，能使相鄰的兩個通道實現兩兩互通。
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.
