The new 3D film explains the advantages of the Hartmann metal-to-metal sealing system in comparison to soft sealing or PMSS systems. When closing the ball valve the internal velocity of the medium increases. The sealing system is now exposed to being struck by high speed debris. In the film you can learn what damage is caused at the inlet and downstream side of a soft sealing ball valve and this will result in expensive repairs.Читать далее
At the annual Celle Wasa Run on the 11th March 2018 the Hartmann Running Team was again able to combine sport, fun and team spirit in their white and blue colours. The preceding training in frosty temperatures had paid off: on the one spring day so far this year almost 30 starters were able to enjoy the run through Celle city centre in T-shirts.Читать далее

With another order from Stadtwerke München, the municipal energy supplier of the Bavarian capital, Hartmann Valves stabilizes its leading market position in deep geothermal applications.
For the new geothermal plant in the “Schäftlarnstraße” the German system supplier will deliver four wellheads with integrated ball valves as well as the installation service.
With the new build of the storage plant in the Lower Saxony town of Jemgum, EWE Gasspeicher GmbH commissioned Hartmann Valves GmbH to supply all brine and gas wellheads, diverse special ball valves and the associated assembly and maintenance service. The „Hartmann concept“, i.e. the use of pure metallic sealing ball valves as wellhead shut-off valves which are absolutely gas-tight even in large nominal bores, had already proven itself in the equipping of other storage plants as highly durable and virtually maintenance-free.Читать далее
At the company outing to the „Hänigser Teerkuhlen-Museum“ Werner Hartmann handed over a Hartmann exhibition valve to the museum manager. Dr. Thomas Degro and the Hänigser “Teerkerle” were very impressed by the imposing valve and its operation. The scraper valve not only serves as shut-off valve, but also as pig launcher or receiver for cleaning the pipeline.Читать далее
With attractive booth design and interesting presentations the Hartmann team successfully took part in the first trade fairs in spring 2017 and was able to establish many new business contacts.
At the GeoTHERM end of February in Offenburg Hartmann for the first time was represented with an own exhibition booth and met many existing customers as well as new international contacts.
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 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.Читать далее
With Hartmann Valves’ new corporate film Christian and Werner Hartmann, the grandsons of the company founder, provide an interesting insight into the production processes and company philosophy of the valve and wellhead manufacturer. Since more than 70 years special ball valves and customized wellheads for extreme process conditions are designed and manufactured at the two German Hartmann facilities in Celle and Burgdorf.Читать далее
