High-Pressure High-Flow Overflow Prevention Valve for Hydrogen Stations - EFV2 Series

Exhibits excellent airtightness! A structure where a small amount of compressed hydrogen flows from the valve even during operation!

The "EFV2 Series" is a high-pressure, high-flow overcurrent prevention valve designed for hydrogen stations. It is an overcurrent prevention valve with a flow diameter of φ10, suitable for piping with an internal diameter exceeding φ5 and for medium-pressure piping. The main material used is JIS G4303 SUS316 with a nickel equivalent of 28.5 or higher. Additionally, the external seal employs a metal seal method using a copper gasket, providing excellent gas tightness. The gas contact parts are designed with wall thickness secured by strength calculations in compliance with the High-Pressure Gas Safety Act. 【Features】 ■ The valve automatically operates to stop the flow when the flow rate on the outlet side of the overcurrent prevention valve becomes excessive. ■ The structure allows a slight flow of compressed hydrogen from the valve even during operation. ■ The valve resets due to the spring force when the pressure on the inlet and outlet sides becomes uniform. ■ The external seal uses a metal seal method with a copper gasket. *For more details, please refer to the PDF materials or feel free to contact us.
