4" 4000SSLG RP Backflow Preventer Valve for Fire Systems Safety

Safeguard your commercial or industrial fire protection assembly and municipal water supply with the Ames Backflows 4" 4000SSLG Reduced Pressure Backflow Preventer Valve. This essential suppression component installs directly into your fire system network to isolate hazards and prevent contaminated water from reversing into the potable public supply during a fire event.

Engineered to comply with strict life safety mandates, this valve satisfies code requirements outlined in NFPA 13 for fire sprinkler system installation and NFPA 25 for routine water-based fire protection system inspection, testing, and maintenance. The reduced pressure zone mechanism reliably blocks hazardous backflow under both back-pressure and back-siphonage conditions, ensuring continuous code compliance and protecting system integrity.
