PZNS587591 Pneumatically operated brass valve system in an (...)

The Haws 6521FR is a fully engineered freeze‑resistant valve assembly intended for single‑bubbler wall‑mounted drinking fountains. Installed on an interior wall where room temperature remains at or above 50 °F (10 °C), it ensures the outdoor fountain remains operational in freezing conditions. It combines a brass pneumatic valve with a self‑draining waste assembly and a flow regulator, enclosed within an insulated galvanized steel box. The system automatically drains leftover water in the supply line back into the mounted cabinet when the valve moves to the off position, maximizing freeze protection. 1/2″ NPT inlet and 1‑1/4″ NPT trap connections simplify integration. The system is lead‑free, meets NSF/ANSI/CAN 61 & 372, CSA certified, and Prop 65 compliant.

Model 6521FR freeze-resistant valve system for use with single bubbler wall mounted fountains shall include a brass pneumatic operated valve, waste assembly designed to drain water left in supply line to fountain, regulator valve to control stream height, insulated galvanized steel mounting box installed on interior wall where temperatures maintain a minimum of 50deg F (10deg C), 1/2" NPT supply, and 1-1/4" NPT trap.
