不銹鋼球閥廠家為您詳細分析：銅球閥和不銹鋼球閥的區別在哪里？
The stainless steel ball valve manufacturer makes a detailed analysis for you: What is the difference between copper ball valve and stainless steel ball valve?
銅球閥和不銹鋼球閥有一下五點區別：
There are five differences between copper ball valve and stainless steel ball valve:
1、材質不同：它們采用的材質完全不同，銅球閥采用的材料主要以銅組成。，不銹鋼球閥采用的是不銹鋼。
1. Different materials: they are made of completely different materials. The copper ball valve is mainly made of copper., Stainless steel ball valve is made of stainless steel.
2、耐腐蝕性不同：銅球閥耐腐蝕性比不銹鋼球閥好，開關操作順暢省力，耐久不漏。不銹鋼不會產生腐蝕、點蝕、銹蝕或磨損以及耐高溫。一般不銹鋼的貴點了。
2. Different corrosion resistance: the corrosion resistance of copper ball valve is better than that of stainless steel ball valve. The switch operation is smooth, labor-saving and durable. Stainless steel will not produce corrosion, pitting, rust or wear and is resistant to high temperatures. Generally, stainless steel is more expensive.
3、溫度不同：按相同壓力環境下，如果介質溫度不超過80度，則用不銹鋼球閥就可以了，如果溫度超過80度則必需要用銅球閥。
3. Different temperatures: under the same pressure environment, if the medium temperature does not exceed 80 degrees, stainless steel ball valves can be used; if the temperature exceeds 80 degrees, copper ball valves must be used.
4、價格不同：銅球閥造價材料比較貴，不銹鋼球閥造價材料比銅球閥便宜。
4. Price difference: copper ball valve is more expensive, while stainless steel ball valve is cheaper than copper ball valve.
5、適用物質不同：不銹鋼球閥可用于控制空氣、水、蒸汽、各種腐蝕性介質、泥漿、油品、液態金和放射性介質等各種類型流體的流動；銅球閥適用于水、溶劑、酸和天然氣等一般工作介質，而且還適用于工作條件惡劣的介質，如氧氣、過氧化氫、甲烷和乙烯等。
5. Applicable substances are different: stainless steel ball valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid gold, radioactive media and other types of fluids; Copper ball valves are suitable for general working media such as water, solvent, acid and natural gas, and also for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
