What is a Check Valve?

A check valve, also known as a non-return valve, is a mechanical device that allows fluid (liquid or gas) to flow in only one direction. Its main function is to stop reverse flow, protecting pipelines, pumps, and equipment from damage.

These valves are widely used in industries such as petroleum industry, water treatment, chemical processing, and power generation.
