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, ensuring the proper and safe operation of fluid systems. Check valves are widely used in various industries such as oil and gas, water treatment, power generation, chemical processing, and HVAC systems. They come in different types, including swing check valves, lift check valves, ball check valves, and diaphragm check valves, each with its own unique design and application scenarios.
