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.
