Inline Check / (NRV) Non Return Valve Manufacturer & Supplier In India
Industrial Pump and Valve by Ambica Machine Tools is a ISO and CE-certified non return valve manufacturer in India, building NRV and inline check valves since 2006. Our non return valves stop reverse flow the moment a pump shuts down, holding pressures up to 10,000 PSI (800 bar) and protecting pumps, instruments, and downstream equipment in chemical, process, and high-pressure systems, all with no manual operation.
Our valves are made in SS 316, SS 304, and carbon steel, so there's a version to suit almost any fluid or duty. As trusted NRV valve manufacturers, we supply inline check valves used across chemical, water, construction, and process plants, and we pair them with our pressure relief valve range where systems need both backflow prevention and overpressure protection. Every valve is tested for correct flow direction and pressure handling before it leaves the floor, and we back each order with material certificates and responsive support.
Inline Check / Non Return Valve Overview
A non return valve, also known as an inline check valve, allows fluid to flow in one direction while automatically preventing reverse flow. This helps avoid pressure loss, equipment damage, and system failure caused by backflow. The inline body design is compact and straight, making it suitable for installations where space is limited. As an experienced NRV valve manufacturer, we design these valves for reliable performance in high-pressure pipelines, pump discharge lines, and testing systems where dependable one-way flow is essential.

More than 10,000 clients worldwide rely on our NRV valves for their reliability, long service life, and consistent performance in high-pressure systems.
CE & ISO Certified
Every non return valve is manufactured under CE and ISO certified processes, meeting industrial quality and safety requirements.
Superior Quality & QC at All Levels
As a trusted non return valve manufacturer, we check every valve for material quality, sealing, and correct flow direction before dispatch.
Used in Critical Applications
Our valves are built for systems where stopping reverse flow is essential to protect equipment and keep operations stable.
Applications of Our Non Return Valves
High-pressure inline check valves rated up to 10,000 PSI are used in systems where one-directional flow is required under extreme pressure. These valves help prevent reverse flow, protect equipment, and maintain pressure stability in compact high-pressure pipelines and tubing systems.
High-Pressure Fluid Transfer Systems
Used in high-pressure fluid transfer lines where one-directional flow must be maintained. The valve helps prevent reverse flow and pressure loss during continuous or intermittent transfer operations.
Pump Discharge and Outlet Lines
Installed at pump discharge points to stop backflow when the pump is shut down. This protects pumps and connected piping from reverse pressure damage.
Chemical Dosing and Handling Units
Used in chemical dosing skids and handling systems to allow controlled forward flow while blocking reverse movement of chemicals. Suitable for systems handling aggressive or sensitive fluids.
Hydro Testing and Pressure Testing Equipment
Commonly used in hydro test and pressure testing setups where pressure up to 10,000 PSI must be held safely in one direction during testing cycles.
Instrumentation and Tubing Lines
Installed in instrumentation, sampling, and tubing lines with NPT, BSP, or tube end connections to protect gauges and instruments from reverse pressure.
Process Lines Requiring Backflow Prevention
Applied in industrial process lines where backflow can affect system performance or equipment safety, especially in compact, high-pressure piping layouts.
