NIBCO resilient wedge ductile iron gate valves provide full flow with minimal pressure drop.
A ductile iron flanged (by mechanical joint) gate valve is designed to be the main control valve in an automatic fire sprinkler system. Ductile iron gate valves flanged by mechanical end connection allow transition of piping systems (steel to cast iron pipe).
NIBCO resilient wedge non-rising stem flow control ductile iron gate valves are used for golf courses and other water installations.
Ductile alloy iron non-rising stem gate valves feature Class 150 raised face-end connections for easy installation and accessibility. With its ductility, these valves display higher physical properties than standard grey cast iron. In addition, stainless steel trim provides additional corrosion resistance above and beyond the standard bronze trim.
