Parker gains TÜV TA-Luft approval for wide range of valve types

According to Parker’s Project Manager, Walter Kummer, “Companies are under growing pressure to limit the environmental impact of their industrial processes. Many of the world’s leading chemical and petrochemical processing companies are based in Germany and are already specifying the use of TA-Luft approved components in their installations, to help implement ‘zero emissions’ and safety design goals. The availability of these products from Parker will provide process system designers with a key competitive advantage – in both domestic and world export markets.”

Parker’s flanged manifold valve products and manifolds for instrument hook-ups are already available in ISO 15848 compliant versions. Independent third-party verification of the products’ design and performance testing phases – an obligatory part of the approval process – was provided by Lloyd’s Register. Following the audit by TÜV Mannheim Süd, which looked at Parker’s design, test equipment and production test procedures, the company is now in the unique position of being able to demonstrate both ISO 15848 class A and TA-Luft approval.

In order to meet these latest, extremely rigorous, environmental standards, Parker has taken its high-quality monoflange and Pro-Bloc flange-ended double block and bleed manifolds – which were already designed for minimal leakage paths – and effectively re-engineered their integral needle and ball valves. The new valves employ a combination of complementary sealing methods, using high performance elastomeric ‘O’ rings to provide enduring resistance to leaks over repeated actuations, combined with traditional graphite packaging rings for fire-safe performance.

The first products that will be made available in TA-Luft versions are Parker’s Pro-Bloc, Monoflange, and Hi-Pro double block and bleed manifolds, and the H-Series valves and manifolds. As standard, products are supplied with integral Parker A-LOK compression tube fitting ends, for high integrity connections to process tubing.
