About Seitz
Eugen Seitz AG, headquartered in Wetzikon, Switzerland, is a technology company specializing in high-pressure valves for gaseous media. The company can look back on more than 50 years of experience in valve manufacturing and produces its products as 100% Swiss Engineering entirely at its Wetzikon site, where they undergo rigorous functional testing. The product range includes solutions for the beverage industry (PET stretch blow molding processes) as well as for energy segments such as hydrogen (HyValve series, SeitzFlexo), Compressed Natural Gas, nuclear power plants and Engine Systems. Together with customers such as Krones AG, customized valve technology is created through co-engineering, for example the blow block for rotary stretch blow molding machines. The valves are used, among other things, at TrueZero hydrogen refueling stations in California and at the Hungarian Paks nuclear power plant. The company supports customers from consulting through spare parts and complaints handling to custom developments.
