Inquiry (采购产品): Aquamatic 420 and 820 Valves Dear sirs, I am looking for some additional information on the Osmonics Aquamatic valves for a compressed air application. I have looked on the GE Website, and only basic information is posted. I would be most interested in 1 to 3" valves, preferably flanged.
