Valve temperature
Thread Content
Valves can be classified into high-temperature valves, normal-temperature valves, and low-temperature valves based on temperature. In what aspects do the temperature differences among these types of valves manifest themselves? In the material of the valve body? Or in the material of the sealing surfaces? Or somewhere else?
Clarify the operating conditions before asking again; check the temperature and pressure curve for the valve material according to B16.34

There are differences in the valve body material and valve structure
It is mainly determined based on the operating conditions of the valve’s medium. The environment also plays a role.
It is mainly reflected in the structural design, such as heat sinks, etc
The main difference lies in the material of the valve body and the sealing surface, which is determined by the operating temperature.
This question is too detailed. There are many differences among valves for high temperatures, low temperatures, and normal temperatures, such as the materials used for the housing and internal components, the structure of the upper valve cover, and the treatment of the sealing surfaces. For high temperatures, the expansion coefficient of the internal components must also be taken into account; for ultra-low temperatures, cryogenic treatment is required. Shouldn’t the original poster first explain what they want to know?
The main difference lies in the choice of material
