LESER GmbH & Co. KG is a German manufacturer focused on safety valves for industrial applications. The company traces its origins to 1818 as a brass foundry and gradually narrowed its scope to safety valves, building a long tradition in safety-focused engineering. Based in Hamburg, Germany, it operates a modern production facility and serves customers worldwide with its valve safety solutions. Its portfolio comprises eight product groups and 38 valve types, offered in a range of materials and sizes from DN 10 to DN 400, or 1/2 inch to 16 inches. The organization produces roughly 130,000 safety valves each year and is active in industry associations such as VDMA, EVA, ASME, and TÜV-Nord to maintain standards. In May 2026, LESER launched a Digital Twin that centralizes valve data, streamlining management and enabling faster, location-independent access.
