Municipal relevance is real but indirect: the DAB Series appears on Hayward's own Water/Waste Treatment segment page, and Asahi's Type-14 is the valve line-up partner for Chem Proline, whose 26-installation reference list is dominated by municipal WTP/WWTP hypochlorite, caustic, HCl and hydrofluorosilicic acid service. Moderate — neither source publishes a municipal-specific diaphragm-valve spec. The beacon indicator is a genuinely operator-facing feature where valve position must be confirmed visually from a walkway.

The beacon position indicator is a genuinely operator-facing feature — a plant walkway view of a diaphragm valve's open/closed state matters when the valve is dosing hypochlorite or caustic and an operator needs to confirm status without climbing down to the pipe rack.
