Customizing a SBC990 to Pressure blasting => advice pinch valve

Since a couple of months I have been in possession of a SBC 990 sandblasting cabinet working on the Vacuum principle.



Now i am looking into converting it to a pressure blasting cabinet with the aid of a 20 gallon sandblasting pot.


I worked out what i have to do to make things fit and am working on the air and media circuit. Using this as a guide

I came to the conclusion i need a pinch valve, Living in Belgium in cant find any local distributors that offer them.

SO anyone know where in Europe i could find them?

Try this.
