Liquid hydrogen valve is an important part of liquid hydrogen storage, transportation and application system. Our company independently develops and produces matching valves for the whole process from hydrogen storage, hydrogen transport to hydrogen use. According to the type of valve, it includes globe valve, check valve, pressure reducing valve, safety valve, ball valve, flame arrester, quick filling joint, etc., to realize medium on-off, pressure control, flow control and safety protection in liquid hydrogen system. Function. The use of aerospace-grade special materials and processes ensures that the valve can still safely and reliably achieve relevant functions under the ultra-low temperature -253 °C working condition, while meeting the requirements of low leakage.
