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 prevents backflow, protecting equipment from damage caused by reverse flow, such as water hammer, and ensuring the proper operation of pipelines and systems. Check valves are widely used in various industries, including oil and gas, water treatment, chemical, and power generation. Check Valve
