Non-return valves, also known as check valves, are integral components in a wide range of fluid and processing systems across multiple industries. In power plants, pharmaceuticals, and fuel systems used in transportation, these valves help maintain the correct flow direction and prevent backflow, ensuring the efficiency and safety of the systems. For example, in nuclear power plants, non-return valves are utilized in various critical applications, such as within dump lines, nitrogen feed systems, and water control systems, to ensure the proper management of fluids and gases in the plant’s operations.
Overall, non-return valves are indispensable in a variety of sectors, ensuring the proper functioning of fluid control systems and protecting sensitive equipment from damage caused by backflow.
