Gas non-return valves for town gas, grid gas, natural and liquid gas, Methane (cleaned Biogas), Hydrogen, Oxygen, Nitrogen, inert gases and compressed air Gas non-return valves / Check valves Safety devices in accordance with EN ISO 5175-2 Type: GRV 20

Non-return check valves are a means of preventing a reverse flow and are to be installed gas line where air is mixed with fuel gas prior to combustion, 

The gas non return valve from LT GASETECHNIK protects ring lines, tapping points or large consumers such as gas mixers, gas mixing systems 

In-line NRVs: This type of non-return valve uses a spring and the flow is allowed when the upstream pressure exceeds the spring tension. Again when the pressure goes below the pressure to overcome spring tension the flow is blocked. Folding Disc NRVs: Mainly used for gaseous or low-pressure liquid service, this type of non-return valves are made in a wafer body pattern.
