CTOnews.com February 6 news, recently, the series of hydrogen bottle valves independently developed by Great Wall successfully obtained the ECE R134 standard certification certificate issued by the German Ministry of Transport (KBA), which is also the first 70MPa E-Mark certificate obtained by a domestic hydrogen energy company.

The solenoid valve has successfully passed many tests such as pressure resistance test, leakage test, limit temperature and pressure cycle test, salt fog test, vehicle environment test, electrical test, vibration test, pre-cooled hydrogen test and so on under the audit of the third-party certification body TUV Nande.

CTOnews.com has learned that E-mark certification (also known as ECE certification) is a general certification of automobiles and their spare parts in accordance with the ECE regulations (Regulation) in the markets of member countries of the Economic Commission for Europe, requiring factory inspection and product testing to meet the certification requirements before a type certificate can be granted. As one of the most stringent license issuing institutions, German KBA has extensive influence and recognition in the global market.

Hydrogen storage cylinder combination valve is an important component to ensure the safe operation of fuel cell vehicles, including solenoid valve, TPRD, one-way valve and other functions. The main function of the solenoid valve is to automatically open / close the high pressure gas in the cylinder and provide the necessary fuel for the fuel cell system.

Weipotential Energy said that the E-Mark certification indicates that the unpotential energy solenoid valve has been recognized by the international market, especially the European Union market, and the system capacity, product capacity and quality assurance capability of unpotential energy have been in the leading level in the industry.

Prior to this, the unpotential energy relief valve products have passed the EC79 certification, and the bottle valve products have once again passed the ECE R134 certification, laying the foundation for entering the international market and further promoting the domestic substitution of hydrogen valve products.
