The NIBCO® cast iron gate valve provides full flow with minimal pressure drop. The cast iron gate valve features a Class 125 flanged, flat face end connection 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.
