Butterfly valves with rubber lined interior
Flomatic's AZURE AWWA Butterfly Valves are now NSF/ANSI standard 61 certified for drinking water. The AZURE is designed to the ANSI/AWWA C504 butterfly valve standard and is available in sizes from 3" to 30". The concentric high strength ductile iron disc with stainless steel edge seating provides minimal pressure drop with low turbulence. On the 24” and smaller designs, it utilizes a lens shaped disc that provides the smallest protrusion possible in the flow stream. The valve seat is simultaneously bonded and vulcanized to the valve body. The entire interior waterway of the valve body is rubber lined to prevent corrosion and extend service life.
