The mixproof valve is controlled by the pressed air. When the valve is closed, the valve is working with two seperate valve body. The two different liquid are passed from their own pipeline. Between the two valve body, there is a draining body. In case there is any leaking from the two liquid, the two liquid goes into the draining body so the two liquid would not mix. And we can drain the leaking liquid from the draining body. When the valve is open, the valve can be worked as a flow diversion valve. The liquid can be transferred from one pipeline to another pipeline.
Please see the valve body type as belows
Application: Food, beverage, dairy, pharmacy, chemical or any food processing industries
