Visit MHA ZENTGRAF at the Hydrogen Technology World Expo 2026 in Hamburg from 20–22 October 2026 in Hall 6, Stand 6J79.

We will be presenting solutions for demanding hydrogen applications at pressures of up to 1000 bar, including switching under full differential pressure, and for temperature ranges from −40 °C to +85 °C. Our growing H₂ portfolio includes ball valves, spindle valves, throttle valves, check valves, double-block-and-bleed valves, and H₂ filters.

Our products are certified in accordance with TPED according to ISO 23826 or ISO 10297, ATEX, SIL, Fire Safe, and Low Emission (ISO 15848-1). They have been successfully tested by external laboratories under realistic conditions using hydrogen and in accordance with customer-specific requirements. The tests demonstrated particularly high levels of internal and external leak tightness.

These results are also reflected in real-world applications: More than 4000 MHA hydrogen valves are already in the market and have been operating successfully for over five years. Renowned customers use our valves in applications including H₂ refuelling stations, compressors, production and storage systems, and MEGCs. Customer feedback and technical assessments after extended periods of operation confirm their high reliability under demanding operating conditions.

We would be pleased to discuss your current application and the resulting requirements regarding pressure, temperature, leak tightness, switching frequency, and safety, and to show you suitable solutions from our portfolio.
