Introduction to Check Valve
A check valve, also known as a non – return valve, one – way valve, or reflux valve, is a mechanical device that allows fluid (liquid or gas) to flow through it in only one direction. Its main function is to prevent backflow, which is crucial in many industrial and domestic applications. In industrial settings, check valves are used in pipelines of chemical plants, power stations, and water treatment facilities to protect equipment from damage caused by reverse flow. In domestic applications, they can be found in plumbing systems to ensure the proper flow of water. Check Valve
