一、产品特点：

          上明牌不锈钢电动四通换向球阀为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。

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.本阀门系列可配置多种驱动装置：
This ball valve can be equipped with several types of operation device.

2.四通球阀介质流向原理：

如图所示，“LL’’型四通球阀只需操作板手或执行器将球体转动90’，可同时对两种介质的流向进行切换，即方便而迅速，实现一阀多用的效果。
