On the occasion of Valve World Expo 2022 in Düsseldorf, the Valve Stars Awards were presented in the categories of valves, actuators, sealing, and automation. In the “Valves” category, Hartmann Valves won with its innovative ball valve design with integrated heating jacket. The new ball valve design is distinguished by the integration of the heating…

Heating valves is particularly necessary for special applications. Heating jackets are used when media must be kept flowable. By maintaining a consistently low viscosity of the media, pump performance can be reduced and damage to the pipeline or valves caused by solidifying solids can be avoided. Traditionally, double jackets are welded onto the outer area…

Hartmann Valves has introduced a new standard in the field of Kelly Valves to the market. As drill string components, Kelly valves serve as safety valves in the drilling rig. In the event of a potential kick, the outflow of the medium through the drill string can be prevented by switching the ball of the…

In northern Lower Saxony, the first project phase of the pilot project “H2CAST Etzel” is starting, with Hartmann Valves as a project partner. This hydrogen R&D pilot project aims to demonstrate the feasibility of large-scale underground hydrogen storage and to test it in operational storage service. H2CAST stands for H2CAvern Storage Transition, i.e., the conversion…
