The difference between copper ball valve and stainless steel ball valve:
1. They use completely different materials. The steel ball valve uses copper, and the stainless steel ball valve uses stainless steel.
2. The copper ball valve has excellent corrosion resistance, smooth switching operation, labor-saving, and durable. Stainless steel will not produce corrosion, pitting, rust or wear, and high temperature resistance. Generally, stainless steel is a bit more expensive.
3. Under the same pressure environment, the price is cheaper than stainless steel, and the medium temperature of the copper ball valve is much higher than that of the stainless steel ball valve if the medium temperature is too high. You must use a copper ball valve! If the temperature of the medium does not exceed 80 degrees. Just use stainless steel ball valve
Professional definition of copper ball valve:
The copper ball valve has a compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas. It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, and is widely used in various industries. The ball valve body can be integral or combined.
Professional definition of stainless steel ball valve:
The main feature of the stainless steel ball valve is its compact structure, easy operation and maintenance. The stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The ball valve body can be integral or combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve materials are divided into 304, 316, 321 stainless steel ball valves.
