Non-Return Valves

Line valve assemblies

The GCE Non-Return Valves prevent the backflow of medical gases, ensuring the safe flow of gases without contamination.

Non-Return Valves

Non-Return ValvesIntroduction

The GCE Non-Return Valves are designed for use in medical central gas systems to ensure that gas does not flow back from equipment and pipes through the central gas system. This feature is crucial, particularly when technical air is drawn from medical air pipes for use in laboratories. By preventing backflow, the GCE Non-Return Valves maintain the integrity and safety of the medical gas supply.

Non-Return ValvesFeatures

Complete Unit

The medical non-return valve unit includes a non-return valve (NRV) with a flow direction arrow, lockable medical shut-off valves, soldering pieces, nuts, and a gas-specific medical quick coupling (QC) for medical breathing air.

Ease of Testing

The non-return medical gas valve is easy to test.

Versatile Quick Coupling

The QC can be used for checking pressure, performing leak tests, and taking gas samples, enhancing its versatility.

Optional Instrumental Air QC

The non return valve unit can also be delivered with a QC for instrumental air, providing additional flexibility.
