Main Products & Services
The H2 99.9MPa Flow Control Valve is connected to the nozzle of the hydrogen dispenser for hydrogen gas refueling at hydrogen refueling stations. Due to the characteristics of hydrogen, if it is supplied to a sealed space, the temperature of the hydrogen gas rises through adiabatic expansion, potentially causing the fuel tank of the hydrogen fuel cell vehicle to explode. To prevent this explosion, the flow rate of high-pressure hydrogen gas is controlled based on the SAE J2601 hydrogen refueling protocol, and the H2 99.9MPa Flow Control Valve is used for this flow control.
The H70 grade (70MPa) check valve for hydrogen refueling stations is a core component (Size: 1/4" ~ 1") that ensures system safety by preventing backflow and maintaining airtightness in ultra-high pressure hydrogen environments reaching 700 bar, and it obtained KS certification in 2025.
