When choosing a low-temperature ball valve, in addition to considering temperature, pressure, and size, the following factors should also be taken into account:
1. * * Material compatibility * *: Ensure that valve materials are compatible with the medium, especially for special media such as liquefied natural gas (LNG), liquid oxygen, and liquid hydrogen.
2. * * Structural design * *: including extended valve cover design, drip tray structure, pressure relief hole design, anti-static structure, fireproof structure, and reverse sealing upward movement structure. These design features help improve the performance and safety of the valve in low-temperature environments.
3. Sealing performance: Choose appropriate sealing materials and designs, such as flexible graphite, PTFE, etc., to ensure sealing reliability under low temperature conditions.
4. * * Operation mode * *: Consider the operation mode of the valve, such as manual, electric or pneumatic, and whether remote control or automation is required.
5. * * Maintenance and Repair * *: Choose valve designs that are easy to maintain and repair to reduce maintenance costs and downtime.
6. * * Standards and Certification * *: Ensure that valves comply with relevant low-temperature application standards, such as GB/T 24925-2019 "Technical Conditions for Low Temperature Valves", as well as necessary industry certifications.
7. * * Cryogenic treatment * *: For valves made of austenitic stainless steel materials, cryogenic treatment is required to improve material properties.
8. * * Degreasing and degreasing * *: Valves that come into contact with liquefied natural gas (LNG), liquid hydrogen, liquid oxygen, and other media need to undergo degreasing and degreasing treatment to avoid media contamination.
9. * * Manufacturing process * *: Consider the manufacturing process of the valve, such as forging and machining accuracy, and whether precision engineering is used.
10. * * Insulation layer * *: For low-temperature valves, insulation layers or jackets may be required to reduce heat transfer and maintain the low-temperature performance of the valve.
11. * * Installation Requirements * *: Consider the installation angle and pressure relief direction of the valve to ensure its correct installation and safe operation.
12. Fire and anti-static design of valves: These designs are crucial for the safety control of flammable and explosive media.
