Company Profile

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.
