WATTS® Dual Check Valve, SD2 Series, 3/8 in Nominal Size, SAE Male NPT, 200 psi, 110 deg F, Stainless Steel Body, 3 in L

The Watts SD2 is a dual check designed for the protection of the water supply from carbon dioxide gas and carbonated water. These substances can flow from post-mix beverage systems and are very acidic. If the acidic water comes in contact with copper tubing or copper pipe, it will cause the leaching of copper salts into the water supply. The dissolved copper if ingested can cause nausea, abdominal pain, and in some cases vomiting. The SD-2 prevents the reverse flow of potentially contaminated water into the potable water supply due to back pressure backflow and is used for continuous or intermittent pressure conditions. The Watts SD-2 is recommended for use on Post-Mix Carbonated Beverage Equipment and dispensing equipment for tea and coffee.
