Ductile Iron vs Cast Steel Valves | Material Selection Guide

Compare ductile iron and cast steel valves by mechanical strength, pressure and temperature capability, corrosion protection, weight, cost, standards, and application. Ductile iron valves provide a lighter and more economical solution for water supply, wastewater, HVAC, and moderate-pressure systems, while cast steel valves offer greater strength and reliability for high-pressure, high-temperature, steam, oil and gas, petrochemical, and other demanding industrial services.
