Overcurrent Prevention Valve 'EFV1 Series' for Hydrogen Stations

The external seal uses a metal sealing method with a copper packing! It demonstrates excellent airtightness!

The "EFV1 Series" is an overflow prevention valve for hydrogen stations. When the flow rate on the outlet side of the overflow prevention valve becomes excessive, the valve automatically activates to stop the flow. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. Even during operation, a small amount of compressed hydrogen flows from the valve section, and when the pressure on the inlet and outlet sides becomes uniform, it is automatically reset by the force of a spring. 【Features】 ■ A structure that allows a small amount of compressed hydrogen to flow from the valve section during operation ■ Automatically resets when the pressure on the inlet and outlet sides becomes uniform due to the force of a spring ■ External sealing uses a metal seal method with copper packing ■ The gas contact parts are designed with thickness secured by strength calculations in compliance with the High-Pressure Gas Safety Act *For more details, please refer to the PDF document or feel free to contact us.
