Ball valve series HFKH1000 for hydrogen refueling at pressures up to 1034 bar At 700 bar refueling of passenger cars, hydrogen is compressed and stored at pressures up to 1034 bar. Latest developments reveal a tendency to 700 bar technology also for commercial vehicles such as trucks and busses. ISO 19880-3 Standard (Gaseous Hydrogen – Refueling Stations – Part 3: Valves) differs between valves for maintenance (Class B) and operation (Class A) purpose. While Class B Valves are only meant to withstand 100 cycles of operation at room temperature, Class A Valves shall withstand 102000 cycles (100000 at RT, 1000 at -40 °C and another 1000 at +85 °C) without losing integrity of the seal system. MHA aims to qualify its HFKH1000 hydrogen ball valve acc. to ISO 19880-3, Class A. Additionally, the shaft sealing design is certified according to DIN EN ISO 15848-1 (low emission). To enable up to 102000 actuations under full differential pressure, the HFKH1000 trunnion valve was designed with special attention to reduced wear and friction. This ensures a maximal level of reliability and sustainability even under harshest conditions. This ball valve can be used for ATEX-relevant applications as it is approved for ATEX IIC (H2) Ex-zone 1, 2G. H2 ball valve series HFKH1000 features Sizes: DN8 (3/8“), DN13 (1/2“) Pressure rating: 1034 bar Connections: threaded, flanged Tested according TPED guideline (ISO 23826) Low emission DIN EN ISO 15848-1 certified ATEX 2014/34/EU - Category IIC 3G compliant Rapid gas decompression proven o-rings Materials according ISO11114
