Introduction to Check Valves
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 commercial applications. For example, in water supply systems, check valves ensure that water flows from the source to the destination without flowing back, preventing contamination and maintaining system efficiency. In chemical processing plants, they are used to prevent the reverse flow of corrosive chemicals, protecting equipment and ensuring safety.
