Introduction to Check Valve
A check valve, also known as a non – return valve or one – way valve, is a type of valve that allows the fluid (liquid or gas) to flow through it in only one direction. It automatically prevents backflow, which is crucial in many industrial and plumbing applications. For example, in water supply systems, it stops water from flowing back to the source; in chemical processing plants, it helps in maintaining the correct direction of the flow of chemicals, preventing cross – contamination and potential damage to equipment.
