Check Valve
Ductile iron is a complex metal alloy containing a mixture of different metals for exceptional properties. Although it is a higher quality material than cast iron, it is still an economical option that will save you money compared to steel alloys. Ductile iron check valves are some of the toughest and best for demanding jobs, with a temperature resistance of over 1000F. Due to their composition, ductile iron valves will never become brittle. So whether you're dealing with low or high temperatures, they'll get the job done.
Check valves such as these control pipes by keeping the flow moving in one direction, preventing blockages and contamination. Some of the many check valve variants are wafer, silent ball, and swing.
