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 prevents backflow, which is crucial in many industrial and commercial applications. For example, in a water supply system, a check valve ensures that water does not flow back into the source, protecting the integrity of the system and preventing contamination. In the oil and gas industry, check valves are used to prevent the reverse flow of oil or gas, which could lead to dangerous situations such as pipeline ruptures or equipment damage. Check Valve
