High pressure hydrogen valve is an important part of high pressure hydrogen storage, transportation and application system. Our company independently develops and produces a full range of supporting valves for high-pressure hydrogen on-board systems and hydrogen refueling stations. According to the general classification of valves, it includes vehicle-mounted system integrated bottle valve, overflow valve, globe valve, ball valve, safety valve, pressure reducing valve, one-way valve, hydrogen refueling gun, hydrogen refueling port, pull-off valve, etc. In the high-pressure hydrogen system, the functions of medium on-off, pressure control, flow control or safety protection are respectively realized. The valve pressure of the high-pressure hydrogen vehicle system is covered to 70MPa, and the valve of the hydrogen refueling station is covered to 140MPa. Special materials and processes are used to ensure that the valves can still perform relevant functions safely and reliably under ultra-high pressure conditions and meet the requirements of low leakage. Benchmark imported first-line brands in terms of requirements, and strive to become a benchmark enterprise for domestic hydrogen valves.
