The valve is a control component in the pipeline transportation system, which 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. In the pharmaceutical industry, the use of valves is relatively large.

For example, in the pharmaceutical industry, pipelines can be roughly divided into two types: API pipelines and preparation pipelines. For example, in the field of pharmaceutical preparations, compared with the field of raw materials, the medium to be transported is more common, mainly concentrated in softened water, purified water, water for injection, pure steam, process compressed air, etc.

For pipelines in the pharmaceutical preparation industry, "clean quality" must be considered in the first place. Therefore, the pharmaceutical preparation industry has higher requirements for the smoothness, cleanliness, flatness, and corrosion resistance of valve equipment.

The author understands that in order to better meet the requirements of the pharmaceutical industry and put more sophisticated valve equipment into the pharmaceutical market, the valve industry is undergoing transformation and upgrading work, adjusting product structure, and developing equipment products with intellectual property rights.

From a strategic perspective, valve companies are actually in a good environment. For example, the implementation of the green sustainable development strategy and the practice of the "Belt and Road" initiative have brought new opportunities to the structural adjustment and industrial upgrading of the valve industry.
