TA LUFT Certification Now Available

October 2013

This October Hobbs Valve successfully completed TA Luft fugitive emissions testing to coincide with the existing ISO15848-1:2006 certification already available for the TVT range of valves.

The test was undertaken at TÜV Rheinland Industrie Service GmbH premises in Cologne under strict environmental conditions. The performed tests also cover the requirements of the TA Luft -Technical Instructions for Air Pollution Control, Section with VDI 2440, Section

The selection of a Class 300 valve required an ambient test pressure to be maintained at 740 psig (51.02 bar) and a 200°C test pressure at 635 psig (43.78 bar) with a pressure variance of +/-10 psig. Utilising Helium as the test medium the valve withstood 4 thermal phases of temperature up to 200°C whilst being operated up to 2500 cycles.

Test results certified by TÜV indicated exceptional performance.

At Hobbs Valve we are supremely confident in the quality and performance of our products, which is why we choose for the tests to be performed away from our manufacturing facility at third party premises.

In August 2012, the Hobbs Valve TVT range of Triple Offset Butterfly Valves had previously successfully passed the Fugitive Emissions test requirements of international standard ISO 15848-1:2006; Industrial valves – Measurement, test and qualification procedures for fugitive emissions – Part 1: Classification system and qualification procedures for type testing of valves (ISO 15848-1:2006).

ISO15848-1 Testing on this occasion was performed by DET NORSKE VERITAS (DNV) in Houston, TX.
