Copper valves are valves made of copper and belong to industrial parts. The manufacturing process was first developed by Ningbo, Zhejiang in China. In the early 1980s, Ningbo, Zhejiang Province took the lead in developing manufacturing processes, which changed the long history of using cast iron valves in China. In the manufacturing process, the sand casting molding process was initially adopted, and the forging process was changed to the forging process in the early 1990s. Development to the beginning of the 21st century, China has developed into the world's copper valve manufacturing center.
According to the selection of control functions, various valves have their own functions, and attention should be paid to their corresponding functions when selecting.
According to the selection of working conditions, the technical parameters of commonly used valves include working scale pressure, maximum allowable working pressure, working temperature (minimum and maximum temperature) and medium (corrosiveness, flammability). When selecting, pay attention to the above-mentioned parameters of working conditions and valve The technical parameters are consistent.
Choose according to the installation structure. The installation structure of the piping system includes pipe thread, flange, ferrule, welding, hose and so on. Therefore, the installation structure of the valve must be consistent with the installation structure of the pipeline, and the specifications and dimensions must be consistent.
