The lead-free brass valve market refers to the global market for valves made from brass that do not contain lead. The use of lead in brass valves, plumbing systems, and other products has been restricted or prohibited by several national and international regulations due to health concerns, particularly related to lead's potential harmful effects on children's development. As a result, manufacturers are increasingly shifting towards producing lead-free brass valves.

The difference between brass valves and bronze valves can be literally distinguished from each other. We can know that the two valves are different in material. According to different compositions, copper alloys are divided into brass and bronze. Copper alloys are formed by adding certain alloying elements (such as zinc, tin, aluminum, beryllium, manganese, silicon, nickel, phosphorus, etc.) to pure copper. Copper alloy has good electrical conductivity, thermal conductivity and corrosion resistance, as well as high strength and wear resistance.

Angle valves are made of many materials. Stainless steel angle valves and brass angle valves are the two better ones. They mainly differ in the following aspects:

Check valve, also known as check valve or one-way valve, has the main function of preventing fluid from flowing back in the pipeline. According to the structural characteristics and application scenarios, check valves can be mainly divided into the following three types:
