Designed for safety, durability, and compliance, the 5094AB Full Port Relief Ball Valve is the trusted solution for managing thermal expansion in potable water systems. Engineered from lead-free brass and certified to NSF/ANSI 61 & 372 standards, this valve meets the requirements of AB1953 and the Buy American Act (BAA) — making it ideal for both residential and commercial applications.
Whether you’re installing in a new build or retrofitting an older system, the 5094AB offers reliable thermal expansion relief with a factory-set integral relief valve (choose from 80 psi, 100 psi, or 125 psi). The full port design ensures unrestricted flow, while the integrated barbed outlet allows for direct drain routing with PEX tubing (ASTM F1807).
