The most important facts of an own Valve Test Center

When I think back 20 years, I nearly cannot imagine how we were able to provide such high quality valves without the means of testing them in such an extensive way like we do this today.

I remember very well the time, when I started at AS-Schneider as a design engineer. Fire Safe Approvals and Fugitive Emission Testing (TA-Luft) had to be done outside the company on a third party test rig. There was no chance to do a pre-testing and it was always very exciting when the third party like TÜV was witnessing the tests. Well, most of the approvals were passed successfully, but I also remember some Type approvals were we failed at the first stage. The disappointment was great and we lost time with the re-design and the second try.

Today we are very glad to operate our TechCenter with 2 Fire Safe test rigs, a fully automated valve test bench, a climate chamber, etc. Once we started our TechCenter, it was so exciting for us to learn what our valves are able to withstand and where they have their limits.

How the position of levers can influence the usability of DBB Valves

Several Ball Valve basic designs are common and therefore a lot of different solutions are available on the market. Especially the position / orientation of the levers have an enormous influence on the usability of the valve, when used in horizontal installations. The following pictures are showing two different options.
