Spring closing arrangements for the prevention of reverse flow the pipelines.
These valves are general purpose valves that are stronger, lighter and smaller than conventional swing check valves and therefore, less expensive to install and maintain
Suitable for higher pressure /temperature (up to 4000C)
Compact design for simple installation between wide ranges of flange types.
It can be mounted in any plane/direction.
Extremely low opening pressures.
Spring assisted silent closing.
Available sizes 15mm to 100mm,suitable for PN6-PN40 and 150/300.
Weight and Dimension are same for class 150 & class 300 valves.
Valves are self-centering type.
Zero leakage for soft seated valves.
The maximum permissible leakage rate shall be 3 cubic centimeters per inch of nominal pipe size for metal-seated  valves.
This NRVs are made completely from bar stock, Non-magnetic.
