At AS-Schneider, we have been experts in the effective control of Fugitive Emissions from valves for more than a decade.
Our Instrumentation Valves and Process Valves are available acc. to ISO 15848-1 and the TA-Luft option acc. to the amendment (status 2021). Our extensive portfolio has been certified by TÜV Süd.
In 2011, we already received the first ISO 15848-1 certificate and have thus basically met the requirements of the new TA-Luft for more than 10 years.

AS-Schneider offers a variety of ISO 15848-1 solutions that comply with the new TA-Luft 2021. Since the tightness class is defined in the TA-Luft, this cannot be selected.
However, in order to find the optimal solution, the following must be considered:
( 1 ) Chemical resistance
Check possible restrictions regarding the seal material (PTFE, Graphite, FKM Elastomer, Bellows). It is important to ensure that the selected seal material meets the specific requirements of your application.( 2 ) Endurance class
TA-Luft does not give any specific information on the endurance class, but it requires that testing and maintenance of sealing systems must be specified in management instructions in order to ensure leak-tightness in the long term. To save this effort, AS-Schneider valves are designed to be maintenance-free under certain conditions.( 3 ) Pressure and temperature
Make sure that the certified pressure and temperature range of the valves is sufficient for your specific application. It is essential that the valves can withstand the operating conditions to ensure reliable and safe operation.AS-Schneider Type | Sealing Material | Max.

The revised TA-Luft Emission Standard refers to ISO 15848-1 to protect the general public and the neighborhood. And to prevent harmful effects on the environment caused by air pollution. All that in order to achieve a high level of protection for the environment as a whole. In our blog article, we explain what impact this change will have on the valve industry.
