Reliable Quarter Turn Valves for Gas Applications

GEMÜ butterfly valves in the GEMÜ R480 Victoria series and the GEMÜ B20 ball valve have been awarded gas approval by DVGW (German Technical and Scientific Association for Gas and Water).

The GEMÜ R480 Victoria 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 regulatory code is used to confirm the ability of these valves to work reliably and precisely in different gas environments.

The butterfly valves are available in nominal sizes DN 25 to DN 600 and can be ordered with the “G” (the marking for gas) special function with immediate effect. The GEMÜ B20 ball valve in nominal sizes DN 8 to DN 65, which also has the “G” special function, is suitable for use with combustible gases. A yellow hand lever is available as an option for better visual identification. A type examination was carried out for both quarter turn valves in accordance with DIN EN 13774.

The GEMÜ R480 Victoria butterfly valve is certified and listed under registration number DG-313CQ0540, and the GEMÜ B20 ball valve under registration number 22-00143-AB01-130.
