 Valve Type 27/DUCTILE IRON/ALLOY
 NIBCO Bronze and Iron Valves
Brass Valves 27/Ductile Iron/Alloy

The NIBCO® ductile iron gate valve provides full flow with minimal pressure drop. With its ductility, the valve displays higher physical properties than standard grey cast iron. The alloy iron gate valve features Class 150 raised face end connections for easy installation and accessibility. Outside screw and yoke (OS&Y) gate valves are recommended when positive shutoff and a quick visual indicator of open/closed position is required. The OS&Y configuration protects the stem threads from contact with the media.

The NIBCO® flanged ductile iron gate valve may be used in commercial and industrial applications, including hot and cold water, HVAC, steam, gas and other general utility services. Please refer to NIBCO technical data sheets, chemical resistance guides and catalogs for engineering and installation information. Choose NIBCO® gate valves for the most specified, versatile and economical valve option in commercial, mechanical and industrial applications. NIBCO® valves are backed by the NIBCO 5-year 125% limited warranty
