This Specification applies to NRVs in the size range DN15 (nominal diameter) to DN300 (½ in NB (nominal bore) to 12 in NB) nominal pipe size. This Specification does not apply to NRVs using external power sources to open or close the valve. However, the general performance requirements may be considered relevant.

Non-return valves are safety devices to prevent backfeeding of gases. WITT non-return valves protect plants, pipelines and outlet Non-return valvepoints against reverse gasflow. They can also be used in accordance with EN 764 section 2 in applications where the maximum temperature does not exceed 70° C (158° F).

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.

Gas Safety Engineering Safety devices, gas non-return valves and gas hose couplings. All safety devices and gas hose couplings are design type-tested and are subject to constant production monitoring by neutral test institutes, such as BAM and UL.The safety devices in accordance with EN ISO 5175-2 (check valves and flashback-resistant gas non-return valves) are tested by BAM and approved by DVGW.
