Anchor Sailing For Valve Development For Hydrogen

Recently, a number of new group standards for hydrogen valves, including the "General Test Method for Cryogenic Valves for Hydrogen", "Safety Requirements and Test Methods for High-Pressure Hydrogen Valves", and "General Technical Specifications for Cryogenic Valves for Hydrogen", approved by China General Machinery Industry Association Released and implemented on November 1, 2022, it fills the gap in the functional safety and testing and evaluation standards of hydrogen valve products in my country.

At present, substantial breakthroughs have been made in the field of hydrogen valve technology, and a variety of representative products such as 70MPa high-pressure bottle-mouth valves and 70MPa pressure-reducing valves have been launched through independent research and development. Safety Standard Guidelines. At present, the products have been widely used in port trailers, heavy-duty logistics vehicles, AGV vehicles, car semi-trailers and other models, and have large-scale supporting capabilities. They have successfully passed the EC79 certification of the German Ministry of Transport (KBA) and are sold to the global market. It has further enhanced the voice of my country's hydrogen valves in the international market. 

At the same time, based on the storage and application requirements of liquid hydrogen technology, Weishi Energy has successively broken through key technical problems such as ultra-low temperature adaptive internal leakage sealing technology in the liquid hydrogen temperature zone and low-power electromagnetic drive technology in the development of vehicle-mounted liquid hydrogen valve parts. A series of valve parts such as liquid hydrogen overcurrent valves and electromagnetic liquid hydrogen stop valves for vehicles have been completed, and the vehicle test has been carried out in conjunction with the liquid hydrogen system. The safety and effectiveness of the products have been fully verified.

This participation in standard formulation marks that Weishi Energy's technological innovation capabilities and product development capabilities have been highly recognized by the industry and related organizations, and it is also another milestone breakthrough for Weishi Energy's active participation in the formulation of relevant national standards, industry standards, and group standards , has very important strategic significance.
