About Göpfert AG

Founded in 1911, Göpfert AG is a manufacturer of valves for industry and shipbuilding, headquartered in Weddingstedt (Schleswig-Holstein). The product range comprises around 30,000 items, including globe valves, gate valves, butterfly valves, check valves, ball valves, strainers, quick-closing valves, high-pressure valves, marine valves to VG standards and firefighting valves. The value chain extends from in-house design through pattern making and its own certified foundry to CNC machining and final assembly on 12,000 m² of production floor space. Products are manufactured in copper alloys (Rg 5, Rg 10, Gbz 10, CuAl10Ni), light metal, grey cast iron, spheroidal graphite cast iron, steel and stainless steel, depending on valve type from DN 8 to DN 600. Customers come from shipbuilding, navy, offshore, refineries, tank farms, port facilities, building/fire protection technology, energy technology as well as the chemical and petrochemical industries. The company produces special valves (OEM) from prototype to series delivery; buyers include the German Navy and renowned shipyards.
