Ductile Iron Valve

Cast iron refers to the cast iron with flake graphite, the main composition is iron, carbon, silicon, manganese, sulfur, phosphorus, is the most widely used cast iron, its output accounts for more than 80% of cast iron production. Ductile iron is obtained by spheroidization and inoculation of nodular graphite, which can effectively improve the mechanical properties of cast iron, especially the plasticity and toughness.

Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, ductile iron has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance. Ductile cast iron has been rapidly developed into cast iron material which is second only to gray cast iron."Iron instead of steel", mainly refers to ductile iron. All valves are made of ductile iron of cast iron to ensure that the best grades of the applicable materials are selected as the raw materials of the product, which is in line with our goal of having the ZECO ball iron gate valve, ball iron butterfly valve, ball iron check valve and other products used for more than 20 years. As a manufacturer of high-quality ball and iron butterfly valves, we always insist on ensuring excellent rubber materials, based on excellent body materials, to create a world-class butterfly valve brand. At the same time, the ball iron check valve in China and around the world's water pump room use case we are also all China's leading, we to build a silent pump room and to protect the pump as a premise, the production of the best energy-saving ball iron check valve.
