Low Temperature Valve

The types of low-temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature globe valves, low-temperature safety valves, low-temperature check valves, low-temperature regulating valves, etc. They are mainly suitable for pipeline transportation and storage equipment that require low-temperature liquids such as liquid oxygen, liquid nitrogen, liquid hydrogen, and liquefied natural gas to reach -196 degrees Celsius. Due to the fact that the output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum and other products are not only flammable and explosive, but also require gasification when heated, resulting in a volume expansion of hundreds of times during gasification. The material of low-temperature valves is very important. If the material is not qualified, it will cause external or internal leakage of the shell and sealing surface; The comprehensive mechanical properties, strength, and rigidity of the components cannot meet the requirements for use and may even fracture. Causing explosion due to leakage of liquefied natural gas medium. Therefore, in the process of developing, designing, and researching low-temperature valves, material low-temperature treatment is the primary and key issue. After years of research and development, Shanghai Meiyan Yipump Valve has accumulated rich experience in design, process, and manufacturing, and has developed a series of low-temperature valve products with complete models. The low-temperature valve products that leave the factory have undergone low-temperature treatment and strict testing. The following low-temperature product drawings are for selection reference only, and our company's drawings shall prevail.
