NEW Flashback Arrestors and Check Valves for Fuel and Air Gas

SuperFlash has a new product line for thermal process systems and heating processes with fuel gas and air mixtures.

The new product line consists of check valves (GRV Series) in accordance with EN730-2 – so-called safety devices without integrated flame arrestor as well as models with check valves and an integrated flame arrestor (GRS Series). The new products are characterized by minimal cracking pressures between 4 and 6 mbar as well as extremely low pressure losses.

These products can be used in thermal process plant applications with a natural gas supply as well as heating processes for welding, cutting, and related processes that are operated with mixtures of fuel gas and air. In this area the safety devices are used to safeguard plants, pipeline systems and tapping points and prevent gas return (check valves, model: GRV) or gas return and flashback (flashback resistant gas non-return valve, model: GRS). The safety devices satisfy the requirements specified in all relevant international standards and directives, they are tested by the BAM Institute in Berlin, Germany and are registered under the DVGW certification mark:
NG-4390CQ0062 (gas non-return valves/check valves - Model: GRV)
DG-4390CQ0061 (gas non-return valves (flashback resistant) - Model: GRS)
