In building piping systems, valves play a role in controlling fluids. Due to the difference in structure and material, the valves produced are also different. In order to ensure that the pipeline system can achieve the highest efficiency, the lowest cost and the longest service life, valve selection is very important. The valve has four main functions: starting and preventing the flow of the medium; regulating the flow of the medium; preventing backflow or backflow and adjusting or releasing the fluid pressure. The choice of building piping system can be considered based on factors such as temperature and medium type.
