Non Return Valve (NRV) One-Way Flow Valve for Industrial and Domestic Use

OurNon-Return Valve (NRV)is designed toallow fluid flow in one direction onlyand prevent backflow in pipelines, ensuring the protection of pumps, compressors, and other critical equipment. This valve automatically closes if the flow reverses, making it essential forliquid and gas systems in both industrial and domestic applications.

Available in a variety of materials and configurations such asSwing Type, Lift Type, Wafer Type, andSpring-Loaded, our NRVs are suitable forwater, steam, air, oil, and chemical lines. Built to industry standards, they offerleak-proof operation, corrosion resistance, and long service life.
