About Armaturen Aichhorn
Armaturen Aichhorn GesmbH is a valve expert based in Krenglbach, Upper Austria, specialising in industrial valves, building services valves and special valves. Founded in 1991 in Wels, the family-run company distributes a broad range of butterfly valves, ball valves, valves, gate valves, check valves, strainers, expansion joints, steam and safety valves, pressure reducing valves, foot valves, pressure gauges/thermometers as well as electric and pneumatic actuators. Beyond classic valve trading, the company contributes its technical expertise especially in the project business – from individual consulting and planning, through configuration of valve actuators, to implementation and commissioning. The Krenglbach site was modernised and expanded in 2024. The product range includes valves made of spheroidal graphite cast iron, grey cast iron, cast steel, stainless steel, brass, bronze and plastics. Customers come from industry (including chemicals, refineries, the paper and steel industries), plant engineering, energy suppliers, municipalities, water treatment and the food industry, as well as from plumbing and installation companies. Since 2022, Armaturen Aichhorn has been part of the international Indutrade Group; in 2026 the company was certified to ISO 9001 and ISO 14001.
