Product Introduction:
After years of manufacturing, we have accumulated rich experience and become increasingly mature in design, process, and manufacturing. We have also developed a series of products for low-temperature valves.
In recent decades, with the development of modern science and technology, there has been an increasing demand for low-temperature valves in engineering projects. Low temperature valves are commonly used in fields such as fertilizers, LNG, and petrochemicals. The medium controlled by low-temperature valves, except for liquid nitrogen and other liquid inert gases, is not only flammable and explosive, but also undergoes gasification during heating or flashing, resulting in rapid volume expansion and easy leakage and explosion. Based on the characteristics of the medium and the requirements for adapting to the use of valves at low temperatures, the design, manufacturing, testing, and installation methods of low-temperature valves are different from ordinary valves.
