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
Stainless Steel Flashback Arrestors
In addition to our standard high flow stainless steel flashback arrestor (model DG91NSS), we now offer three additional versions to cover a much larger range of flow rates and situations. Choose from our model DGN for standard flow applications all the way up to our models ESF and Demax designed for high flow manifold applications. Now no matter what application you have, we can provide a flashback arrestor made from stainless steel and suitable for use with higher purity gases, and in more demanding environments. Stainless steel flashback arrestors are designed for oxygen, hydrogen and other flammable gases where all stainless steel type 316 with Viton or other elastomers are desirable. These arrestors are standard with NPT connections; however they can be specially adapted and tested in our lab with a wide variety of connections, including Swagelok tube
