Hartmann Valves is a leading manufacturer of ball valves, pigging valves and wellheads. Design, assembly and tests are carried out solely in the facilities in Celle and Burgdorf, Germany. Traditionally rooted in the oil and gas industry, the innovative family business with 200 employees provides ongoing support for its customers on the path to renewable energies such as geothermal or hydrogen.
For 75 years Hartmann products have provided the highest level of safety through their robust and long service life – even with dangerous and corrosive media. Designed to customer and project specific requirements, the metal-to-metal sealing ball valves are gas-tight, even at high pressures up to 690 bar. Special designs for temperatures up to 550°C or high cycles up to 200,000 per year are available and users benefit from low maintenance effort. Additional safety is provided by the Double Isolation and Bleed (DIB) option or the Twin Ball Valve (TBV) design – double ball valve with up to four barriers in one valve.
Safe hydrogen applications
Special hydrogen valves for have been used in the petrochemical industry for many decades. With the energy transition, the demanding hydrogen medium will increasingly be found in other fields of application – from electricity generation (such as power-to-gas), through transport, to processing and mobility. The underground storage of hydrogen in salt caverns constitutes an environmentally friendly and safe solution for storing large amounts of energy to balance between power generation and demand. Here, Hartmann wellheads form a secure interface between underground and above-ground plant. As a leading system supplier in Europe, several hundred wellheads are installed at crude oil, natural gas, helium storage facilities and in these days also the first wellheads for European hydrogen storage projects have been installed.
