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 through it in only one direction. It automatically prevents backflow, which is crucial in many industrial and domestic applications. Check valves are widely used in plumbing systems, water treatment plants, oil and gas pipelines, and various other fluid - handling systems. They come in different types, such as swing check valves, lift check valves, ball check valves, and diaphragm check valves, each with its own unique design and application scenarios.
