The non return valve unit is intended for use in medical central gas systems to secure that gas does not flow back from the equipment and pipes through the central gas system. This is very important for example when technical air is taken from medical air pipes for use in laboratories.
The non return valve unit consists of a non return valve (NRV) with flow direction arrow, lockable medical shut off valves, soldering pieces, nuts and a gas specific medical quick coupling (QC) for medical breathing air.
This design makes the NRV very easy to test
The QC can also be used for checking the pressure, doing leak tests and take gas samples
The NRV unit can also be delivered with QC for instrumental air
