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. For example, in a water supply system, a check valve ensures that water flows from the source to the destination and does not flow back, protecting pumps and other equipment from damage. In the oil and gas industry, check valves are used to prevent the reverse flow of oil or gas in pipelines, maintaining the integrity of the system.
