New DVGW gas approval for quarter turn valves

The GEMÜ R480 butterfly valve series and the GEMÜ B20 ball valve have been awarded gas approval by DVGW, the German Technical and Scientific Association for Gas and Water.

The GEMÜ R480 and GEMÜ B20 are suitable for use with different gases, such as natural gas and biogas (the main component of which is methane), propane and liquid gases containing butane. They are approved for gas production, treatment and injection. This includes use for combustible gases in gas families two and three in gas burners and gas appliances. It also includes the use of hydrogen. The DVGW approval confirms the ability of these valves to work reliably and precisely in different gas environments. 

The GEMÜ R480 butterfly valves are available in nominal sizes DN 25 to DN 600. The GEMÜ B20 ball valve in nominal sizes DN 8 to DN 65 is suitable for use with combustible gases. A type examination was carried out for both quarter turn valves in accordance with DIN EN 13774.
