Our E Series Manifolds, Monoflanges as well as our Ball Valves and VariAS-Blocks are available with the TA-Luft option according to the amendment (status 2021).
Our extensive TA-Luft compliant portfolio has been certified by TÜV Süd.
TA-Luft amendment 2021
On December 1, 2021, the amended Technical Instructions on Air Quality Control (TA-Luft) came into force. It sets strict limits for pollutant emissions from plants subject to immission control approval.
The most important change in valve specifications is the adoption of the ISO 15848-1 standard, which specifies how a valve is to be tested and gives the parameters for classification.
After the transition period expires in 2025, the requirements must generally meet the state of the art and thus the emission level of new plants. For plants in the planning or installation phase, care must be taken to ensure that valves, pumps, compressors or even flange connections directly comply with the specifications of TA-Luft.

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 resistanceAre there restrictions on the seal material (PTFE, Graphite, FKM Elastomer, Bellows)?
( 2 ) Endurance classTA-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 temperatureIs the certified pressure and temperature range sufficient for the application?

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.Impact of revision of the TA-Luft on the valve industry
