Non Return Valves (NRV) are designed to allow fluid flow in one direction only and automatically prevent reverse flow. These valves operate without manual control, ensuring system safety, equipment protection, and efficient flow control. Non Return Valves are widely used in water lines, pump systems, oil & gas pipelines, steam lines, and chemical industries.
