Valves from the MSA Workshop in Denmark and Romania

Denmark: Heating of the Future with Ørsted

We supplied gray ball valves (BV DN 600 PN 25) to Denmark for Ørsted, a global leader in sustainable energy. Our valves will ensure the reliable transport of hot water for district heating, which is key to efficient and ecological heat supply.

Romania: Reducing Emissions with OMV Petrom

In Romania, our valves helped modernize a compressor station for OMV Petrom. The delivery of white ball valves contributed to reducing operational risks and emissions, thereby supporting efforts to lower the industry's environmental footprint.

We are thrilled that our valves are at the heart of such important projects. Whether supporting sustainable energy or reducing the environmental burden, products from MSA demonstrate their quality and reliability all over the world.
