What Seitz Valve does

Seitz Valve (legal entity Eugen Seitz AG) is a privately held Swiss industrial manufacturer specializing in high-pressure solenoid valves for gaseous media, founded over 50 years ago and headquartered in Wetzikon, Switzerland, with a wholly-owned subsidiary in Shanghai, China. The company's product portfolio is organized around two end-market verticals: Beverage/PET (valve solutions for stretch blow molding machines, including proprietary air spring valve technology that reduces energy consumption by 20%) and Energy (hydrogen refueling, compressed natural gas, engine systems, and nuclear power plant isolation valves). Its flagship hydrogen product line, the HyValve series, supports up to 1,000 bar pressure and flow rates up to 300 g/s, with the modular HyValve Mosaic (launched 2024) and SeitzFlexo (unveiled 2025) extending the platform; products carry CE, ATEX, IECEx, CCC, and KCs certifications enabling global hydrogen market access.

The company employs 51-100 people, with 23 dedicated to R&D including apprentices, and operates a sales-led, direct enterprise go-to-market model emphasizing co-engineering partnerships with customers such as Krones AG (PET), FirstElement Fuel (US TrueZero hydrogen refueling stations), Baixing Machinery (China PET), and Paksi Atomerőmű (Hungary's nuclear power plant, served via channel partner Armatech). Revenue is generated primarily through hardware sales of valves and valve blocks, supplemented by ServiceKit spare parts and technical consulting services; pricing is not publicly disclosed and follows a custom-quote model via inquiry forms. Distribution relies on a Global Sales team plus the Shanghai subsidiary and regional channel partners, with marketing executed through content, trade shows (DrinkTec, Hydrogen Technology World Expo), and direct consultation. The company appears founder-managed (CEO Fabian Seitz, Chairman Ronald Fehlmann) with no disclosed external institutional investors or funding rounds.
