一、產品特點：
上明牌不銹鋼電動四通換向球閥為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。
Features
Four-way direction changeable ball valve is a kind of ball valve with X-pattern vertical bore.It s feature is, the ball valve s two bores
are arranged to be X-pattern ,and its four bores are connected to each other two of adjacent bores can be connected to each other.
1.本閥門系列可配置多種驅動裝置：
This ball valve can be equipped with several types of operation device.
2.四通球閥介質流向原理：
如圖所示，“LL’’型四通球閥只需操作板手或執行器將球體轉動90’，可同時對兩種介質的流向進行切換，即方便而迅速，實現一閥多用的效果。
