Hydrogen valves are used in the storage, transportation, and transfer of liquid hydrogen to precisely control its flow and
pressure, ensuring system safety and stability. They can automatically close in emergencies to prevent leaks and provide
convenient isolation during system maintenance. Valves also regulate flow to support hydrogen processing and ensure stable fuel supply in applications such as hydrogen fuel cells.
Applied in energy, petrochemical, metallurgy, aerospace, nuclear industry, railway, air separation, oxygen production, petroleum, chemical, pharmaceutical, chemical fertilizer, electric power, urban construction, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other industries of low temperature, cryogenic occasions.

Manufacturing And Inspection Of Cryogenic Valves:
Strict manufacturing technology and special equipment have been developed for the low-temperature valves produced, and strict quality control has been carried out for the processing of parts.After special low temperature treatment, the rough machined parts are placed in the cooling medium for several hours (2-6 hours) to release the stress, ensure the low temperature performance of the material, ensure the finishing size, in order to prevent the valve in low temperature working conditions, due to the temperature change caused by deformation and leakage.Valve assembly and ordinary valves are also different, parts need to go through strict cleaning, remove any oil, in order to ensure the use of performance.
