At first, butterfly valves were used if a tight closure wasn’t essential. Using rubber or elastomeric materials, they were eventually manufactured with fairly tight seals that provided good shutoff like other types of valves. The butterfly valve is used where there is limited space. Unlike gate valves, butterfly valves can be operated in either the open or closed position in addition to throttling or regulating flow. Compared to a gate valve, a butterfly valve has a small pressure loss.
Due to their higher ductility rating (hence the name), ductile iron butterfly valves will conform more to the swaying. Despite ductile iron’s good damping properties, cast iron is still highly recommended for use on heavy or loud machinery since it is more durable and doesn’t soundproof as well as ductile iron.
While the chemical composition of ductile iron and gray iron is similar, metallurgical treatment during the casting process modifies its structure to provide mechanical properties similar to carbon steel, while retaining its superior corrosion resistance in some environments. This change in metallurgical structure makes it an excellent material for butterfly valve bodies.
