Non Return Valve

A Non-Return Valve (NRV), also known as a check valve, is a mechanical device used to allow fluid to flow in one direction only and prevent backflow in piping systems. It ensures that fluids do not reverse direction, which can damage equipment or disrupt system operations. Non-return valves are commonly used in various industries, such as water treatment, oil and gas, and chemical processing, to maintain pressure, prevent contamination, and protect pumps, compressors, and other equipment from reverse flow.
