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 automatically prevents backflow, which is crucial in many industrial and plumbing systems. For example, in a water supply system, a check valve ensures that water does not flow back into the pump when the pump stops, protecting the pump from damage. In chemical processing plants, check valves prevent the reverse flow of corrosive or hazardous substances, safeguarding the entire production process.
