719 Series Double Check Valve Assemblies

Watts 719 Series double check valve assemblies are used in plumbing systems to prevent the backflow of water and protect the potable water supply from contamination. These backflow preventers feature bronze alloy construction for structural rigidity and corrosion resistance. They are further coupled with elastomers that resist the effects of chloramine. These backflow preventers have a separate access and a top-entry check valve arrangement that facilitates convenient maintenance procedures. They have a maximum working pressure of 175 psi (12.06 bar).
