NRV

An NRV (Non-Return Valve), also known as a check valve, is a device designed to allow fluid to flow in one direction while preventing backflow. It is commonly used in various applications, including water systems, pumps, pipelines, and industrial equipment, to maintain pressure and ensure fluid flows in the desired direction. NRVs are critical for protecting pumps, compressors, and other machinery from damage caused by reverse flow, helping to maintain operational efficiency and prevent contamination.
