Milwaukee Fire Butterfly Valve | Sprinkler System Secure

Secure your commercial, industrial, or residential fire sprinkler infrastructure with the Milwaukee Fire Butterfly Valve. This essential control valve installs directly into fire suppression piping to manage main lines, branch lines, risers, and drops. Engineered to regulate fluid pathways, it delivers reliable on-and-off functionality and positive flow isolation for system maintenance, testing, and emergency shutdowns. The tight seal on its machined ends maintains system pressure and prevents costly water loss, while ensuring unimpeded full flow during active fire suppression.

To satisfy life safety requirements and ensure life-safety system integrity, installations must strictly adhere to the guidelines set forth in NFPA 13 for the installation of sprinkler systems, as well as NFPA 25 for the inspection, testing, and maintenance of water-based fire protection systems. Compliance with these governing standards ensures your isolation valves operate reliably when subjected to operational pressures during routine testing or emergency protocols.
