Watts SD-3 Dual Check Valve with Atmospheric Port and Strainer, 3/8 in.

The Watts SD-3 (0061667) is a 3/8 in. dual check backflow preventer built for carbonated beverage machines, with a strainer and an atmospheric port. It keeps carbonated water and carbon dioxide gas from being pushed back into the potable supply by backpressure.

The stainless steel body has female NPT ends and internal rubber parts, plus a wye-pattern strainer and an atmospheric vent. It handles continuous or intermittent pressure and suits post-mix soda equipment as well as tea and coffee dispensers. If the second check fails, the atmospheric port shows it visibly, making inspection quick.
