Our company has established strict manufacturing process and special equipment for the low-temperature valves, and strictly controlled the processing quality of the 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, and ensure the finishing size, so as to prevent the leakage of the valve due to the deformation caused by the temperature change under the low temperature condition. The assembly of the valve is also different from the ordinary valve. The parts need to be cleaned strictly to remove any oil stain to ensure the performance.
