Valves play a crucial role in the semiconductor manufacturing process. These valves not only control the flow of various gases and liquids but also ensure the high purity of the production environment and the stability of the processes. Semiconductor production requires extremely high environmental purity, and even the slightest impurity can lead to reduced product performance or even damage. Therefore, the primary role of valves in this field is to precisely control the flow of fluids (including gases and liquids), prevent contaminants from entering the system, and maintain the stability of process parameters.
