液相自动切换阀（LAX）

Automatic Liguid Change-over Device(LAX)

跟气相自动切换阀一样，液相切换阀是在两条LPG（液）供给线之间自动切换预备方与使用方。

As with the change over of gaseous phase LPG. this device automatically excecutes the change over from the service side to the reserve side for two separate liquid phase LPG supply lines. Its use is required when using the vaporizer.
