What are high temperature valves? 

It is necessary to consider the working temperature and compatibility while choosing a valve design and material. High temperature valves are used in various industrial settings, such as petrochemicals, chemical plants, fertilizer factories, electric power stations, and metallurgical facilities. Different materials are used for making such high-temperature valves based on the working temperature. Generally, high temperature valves are defined as valves that can operate at a high temperature of around 450℃ or greater. 

What are low temperature valves? 

Low temperature valves are those that are designed to be used in low temperature ranges between 0° to -29°C or further lower temperatures. Such valves usually come with a soft seated construction that can be fitted into a wide range of thermoplastic inserts and elastomer seals. You should consider choosing appropriate materials for low temperature valves applications. It is because low-temperature carbon and steel materials are acceptable only if it meets certain service conditions and pressure ratings. You must ensure that the chosen material is suitable for a minimum design temperature. These valves are mainly used for numerous corrosive and dirty applications with toxic substances. 

Types of high temperature and low temperature valves 

The significant differences between high and low temperature valves are in the material used to make the valve and the design. There are several types of high temperature valves like, high temperature gate valves, check valves, ball valves, butterfly valves, needle valves, etc. Similarly, you can also find all these valves built with materials suitable for low temperature requirements. High temperature valves are made of materials that can withstand certain high temperature ranges and pressure. Likewise, low temperature valves come with materials suitable for temperatures below 0 °C. 

Conclusion 

Valves used in high and low temperature applications require specific design features and materials to function properly. It is because they require some characteristics and features different from ordinary valves. Special care must be taken when choosing such valves so they are safe to use at extremely low or high temperatures. The information provided here will be useful if you are looking for information regarding low or high temperature valves.
