Cast Iron Reflux Valves

Cast Iron Reflux Valve

The Cast Iron Reflux Valve, also known as a Non-Return Valve (NRV), is a robust and reliable valve designed to allow fluid flow in one direction only and automatically prevent reverse flow in pipelines. Manufactured from high-quality cast iron, this valve ensures durability, corrosion resistance, and smooth operation even under continuous use.

It operates using a swing-type or lift-type disc mechanism that opens under forward pressure and closes automatically when the flow reverses, protecting pumps and pipelines from potential damage. The flanged-end design ensures easy installation and secure connection in water supply, sewage, and industrial systems.
