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