Successful changeover: The Xmas tree with ball valves

Within the scope of overhauling several Xmas trees for gas production, a completely new design of construction was decided on: In the place of Xmas trees with gate valves, solid block Xmas trees with integrated ball valves have already been in operation at several North German locations since 2018. This concept unites the preferences for a compact design with the advantages of gas-tight ball valves over gate valves – at high and in particular also low pressures. Also decisive was the positive experiences with safety ball valves as complementing quick-closing valves in the above-ground installations. The innovative design, which was developed in close collaboration between Hartmann Valves and the operator, provides not only for increased safety and simple operability but also for significantly reduced maintenance requirements.
