About 800 Hartmann ball valves are installed in the upper Bavarian DEA gas storage facility Wolfersberg, the deepest gas storage in Europe. A very high safety level as well as plant availability are critical.
When old shut-off valves had to be replaced, Hartmann designed extra compact Twin Ball Valves (TBVs), which are bubble-tight and solve problems of space limitation.
“The extreme shortening of the TBV system was a great job. Now we are able to renew the old isolating section without any problems”, says Markus Schuster, Plant Manager at DEA Deutsche Erdoel AG.
