In Previous articles, we discussed about Quality factors of China brass ball valves and Quality Test for China Brass Ball Valves, as an important part of the quality, materials play a critical role, especially for brass valve performance and healthy considerations. There’re four main aspects to Select China Brass Valve Material: 1. Healthy consideration: Lead (Pb) is a kind of chemical that can dissolve and contaminate water, and make affect the health of people, such as mental health of children. Materials that have high lead rate are not suitable and avoided for drinking water system. 2. Applications of valves: working pressure, working temperature, flow media type. 1.
