The company was established as a dependent trading company of Gustaf Fagerberg AB, Gothenburg. Only one year later, the transformation into "GEFA Industriearmaturen GmbH" – today's "GEFA Processtechnik GmbH" – was completed. Since the beginning the Valve technology (e.g. butterfly valves and ball valves) is the company’s core business. Over the years, the commercial products have given way to our own products which have been influenced by customer requirements and our product experience. In the course of the company’s development, our product range has been expanded by another main pillar – Filter Technology. We do offer innovative and specialized products for the use in the diverse application range of water supply and distribution as well as general industry. Our product portfolio is rounded off by Single-Use-Systems. We are looking forward to offering you our innovative power in connection with the know-how we have gained over the years.
