We are a Czech manufacturer of industrial valves for both nuclear and thermal power plants, chemical and petrochemical plants. We build on the more than 60-year tradition of development and production of industrial valves in Opava, connected with the SIGMA concern and the Minerva company. We specialize in the production of valves for nuclear energetics and today we have dozens of references from both the nuclear power plants and thermal power plants, chemical, petrochemical and gas industries. Except nuclear valves, we offer a wide portfolio of industrial valves made of carbon, alloy and stainless steel, which we supply to more than 25 countries around the world.
