Thermal Expansion Ball Valve | 5094AB Series | FNPT x FNPT
Thermal Expansion Ball Valve | 5094AB Series | FNPT x FNPT
Designed for safety, durability, and compliance, the 5094AB Full Port Relief Ball Valve provides reliable thermal expansion control in potable water systems. Engineered from lead-free brass and certified to NSF/ANSI 61 & 372, this valve meets AB1953 and Buy American Act (BAA) requirements — ideal for both residential and commercial installations.
Whether you’re installing new systems or retrofitting existing lines, the 5094AB offers dependable thermal expansion relief through a factory-set integral relief valve (available in 80 PSI, 100 PSI, or 125 PSI settings). The full port design ensures unrestricted flow, while the integrated barbed outlet provides a simple, direct drain connection for PEX tubing (ASTM F1807).
