A flanged ductile iron gate valve is ideal for applications involving hot and cold water, HVAC systems, steam, and gas, as it provides full flow with minimal pressure drop. Made from ductile iron, this type of valve benefits from enhanced physical properties, particularly its high ductility, making it durable and resistant to impact. The flanged end connections ensure easy installation and accessibility within piping systems. For applications that require a clear visual indication of valve position and reliable shutoff, OS&Y (Outside Screw and Yoke) gate valves are a preferred choice, as they allow operators to quickly see if the valve is open or closed.
