1. They use completely different materials, copper used for steel ball valves, and stainless steel used for stainless steel ball valves. 2. The copper ball valve has excellent corrosion resistance, smooth switching operation, labor-saving, and durable and non-leakage. 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. The stainless steel ball valve can be used. Turn left|turn right Copper ball valve Professional definition: Copper ball valve is compact in structure, reliable in sealing, simple in structure and convenient in maintenance. The sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium. Operation and maintenance are suitable for general working media such as water, solvents, acids and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., and are 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 stainless steel ball valve is its compact structure, easy to operate and maintain. Stainless steel ball valve can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Type of fluid flow. 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.
