The heating of valves is particularly necessary for special applications. Heating jackets are used when media must remain fluid. Due to the constant low viscosity of the media, pump capacities can be reduced and damage caused by solidifying solids to the pipeline or the valves can be avoided. Traditionally, double jackets are welded to the outside of the valve body to heat the media. The new ball valve design from Hartmann Valves integrates the heating jacket into the ball valve body and eliminating the need for welding double jackets.

The winners of the Primus Award were announced at the DIAM 2021 in Bochum. In the VALVE category, the winner was Hartmann’s new pigging ball valve, which has been submitted for patent. The new Hartmann pigging ball valve with multiple safety barrier to the sluice room enables the safe and easy launching and receiving of […]

Managing director Werner Hartmann explains the technical and commercial advantages of using ball valves instead of gate valves at the wellhead. It will be demonstrated how Hartmann ball valves lead to higher safety, reduced environmental impact, increased plant availability, minimized maintenance effort and thus lower operational costs. The video shows the comparison by means of […]

Hartmann special ball valves assure safety in gas turbine applications worldwide. For the Siemens turbines SGT5-4000F (V94.3A) and SGT5-2000E (V94.2) and Ansaldo turbines AE94.3A and AE94.2 standard shut-off or special designed multi-way ball valves are available as reliable combination with different actuators. They are implemented for diverse services with the media fuel oil, fuel gas, […]

In addition to special hydrogen ball valves and wellheads Hartmann Valves now also offers material suitability and hydrogen leak-tightness tests for challenging hydrogen (H2) applications. Reliable shut-off valves, the right material selection as well as standardised pressure tests help users to increase the operational safety in existing and new hydrogen application areas. Durable special Hartmann […]

In order to enable safe and reliable shut-off even at temperatures below -100°C, Hartmann has developed various ball valve designs with construction features and materials suitable for low temperatures. Soft sealing valves often reach their limit when the main seal between ball and housing (seating) fails. The soft material contracts at low temperature and as […]

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 […]

At the 37th Celle Wasa run on the 10th March 2019 many of the blue-and-white «Hard» men, women and children were once more on route at the double through the town centre. «Hard» in the truest sense of the word – as the 30 or so participants didn’t shy away from the adverse weather conditions […]

Since the start of 2019 Peter Wegjan has been overseeing the areas of chemical, petrochemical and plant construction at Hartmann Valves and advises customers on ball valve shut-off solutions for special application fields. As a chemical engineer he has experience in sector-related sales and management both home and abroad and was active over many years […]
