NRV Check Valve Manufacturers In Delhi

NRV Valve Industry Insights, and Technology

Non-Return Valves (NRVs), also called check valves, are critical components in industrial piping systems. They allow fluid flow in one direction while preventing backflow, protecting pumps, pipelines, and equipment from damage.

FAQs About Check Valves

1. What is an NRV check valve? An NRV check valve is a mechanical device that allows fluid to flow in one direction and automatically prevents reverse flow.
2. What types of NRV check valves are available? Common types include swing check valves, lift check valves, ball check valves, and wafer check valves.
3. Where are NRV check valves used? They are used in water treatment, oil and gas pipelines, chemical processing, power plants, HVAC systems, and industrial fluid systems.
4. How do NRVs prevent backflow? The valve opens when fluid flows in the intended direction and closes automatically when flow reverses, using gravity, spring action, or pressure difference.
5. What materials are NRVs made from? Valves can be manufactured from stainless steel, carbon steel, cast iron, bronze, or plastic, depending on fluid type and temperature.
