Different materials: They use completely different materials. The copper ball valve is mainly composed of copper, and the stainless steel ball valve is stainless steel.
The corrosion resistance is different: the copper ball valve has better corrosion resistance than the stainless steel ball valve, and the switching operation is smooth and labor-saving, and it is durable and does not leak. Stainless steel will not produce corrosion, pitting, rust or wear, and high temperature resistance.
Different temperatures: Under the same pressure environment, if the temperature of the medium does not exceed 80 degrees, stainless steel ball valves are sufficient, and if the temperature exceeds 80 degrees, copper ball valves must be used.
The price is different: the cost of the copper ball valve is more expensive, and the cost of the stainless steel ball valve is cheaper than the copper ball valve.
Different applicable materials: stainless steel ball valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid gold and radioactive media; copper ball valves are suitable for water, solvents, acids and natural gas Such as general working media, but also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
