Who we are

Founded in 1969, InterApp AG is an international valve solutions company headquartered in Rotkreuz, Switzerland. InterApp develops, manufactures and distributes industrial valves for the safe transport and regulation of liquids, gases and solids. The product range includes butterfly valves with metal and plastic housings, ball valves including PTFE-lined versions, gate valves, check valves, diaphragm valves, strainers, rubber expansion joints, as well as actuators, positioners and fittings made of plastics such as PVC-U, PVC-C, PP, PE and PVDF. In-house butterfly valves are manufactured in Switzerland in a flexible production setup, complemented by certified InterApproved third-party products. An in-house research and development team creates customised valve solutions for demanding industries. The valves are used, among other things, in water and wastewater engineering, water treatment, the chemical and petrochemical industries, power plant and marine engineering, and the electronics and semiconductor industries. Since joining the international AVK Group, InterApp has offered a comprehensive portfolio for industrial and municipal applications from a single source.
