Hayward® TBZ Series True Union "Z-Ball" Valves for Sodium Hypochlorite

Sodium hypochlorite is inherently an unstable compound. Two things can happen to it in a piping system that will affect the choice of a valve. Sodium hypochlorite can decompose over time, which results in the formation of crystalline salts, and as it decomposes, one of the decomposition by-products is oxygen gas. The Z-Ball valve effectively vents the gases while keeping the inner valve surfaces constantly wetted, ensuring problem-free use. Eliminates the conditions required for the gas accumulation and salt crystallization.
