Introduction to Check Valve
A check valve, also known as a non – return valve, is a mechanical device that allows fluid (liquid or gas) to flow in one direction only. It prevents backflow, which is crucial in many industrial and domestic applications. In water supply systems, check valves ensure that water flows from the source to the user and does not flow back, protecting pumps and other equipment from damage. In chemical and petrochemical industries, they are used to prevent the reverse flow of corrosive or hazardous substances. Check valves come in various types, such as swing check valves, lift check valves, and ball check valves, each with its own characteristics and applications. Check Valve
