The most outstanding characteristics of cast iron ball valve is low cost, so it can save the purchase budget largely for most customers. But one big defect for this kinds of material is that it is easy to be rusted, so in order to avoid this disadvantage, most cast iron ball valves will go through three way surface treatments as below:
1 alloy method (mainly in the process of iron incorporation of some metals such as chromium and manganese)
2 surface covering method (mainly gold plating and painting)
3 sacrificial anode method (that is, using a more active metal such as zinc to form an electrochemical reaction with iron, which first reacts with zinc to protect iron)
