Liang Chuan Company strict manufacturing process and special equipment are adopted for the produced low-temperature valves, and the quality of parts is strictly controlled. After special low temperature treatment, the rough 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 finished size to prevent the valve from working in low temperature conditions. Leakage due to deformation due to temperature changes. The valve assembly is also different from ordinary valves. Parts need to be strictly cleaned to remove any oil stains to ensure performance.


Notes When Use
