The NIBCO® cast iron gate valve provides full flow with minimal pressure drop. The gate valve features a Class 250 flanged, raised face end connection for easy installation and accessibility. Outside screw and yoke (OS&Y) gate valves are recommended when positive shutoff is required and a quick visual indicator of open/closed position is needed. The OS&Y configuration protects the stem threads from contact with the media.

The NIBCO® flanged cast 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.
