Refit in record time

Optimal planned maintenance of safety ball valves enables recommissioning on schedule

The natural gas field Völkersen located in the north-western part of Lower Saxony and operated by DEA is one of the most productive in Germany. When operating, as well as during service and preventative maintenance of the surface facilities and the production wells conducted by DEA Niedersachsen, safety has top priority. All components of the plant have to fulfill the highest technical requirements at any time. In the course of regular 5 yearly maintenance of the Central Gas Drying Plant about 20 ball valves manufactured by Hartmann Valves were inspected and overhauled in September 2016. Thanks to early planning and close cooperation all valves could be reconditioned in a short period and taken back into operation right on schedule.
