If you have the chance, you’ll notice it: in petrochemical main pipelines, during equipment inspection or maintenance; in LNG/CNG storage and transportation systems, when preventing flammable and explosive gas leaks; and in pharmaceutical high-pressure reaction pipelines, during some low-temperature synthesis reactions. Cryogenic DBB valves are everywhere. Some may wonder: What is a Cryogenic DBB valve? What does it do? How does it differ from ordinary valves? Don’t worry, we’ll slowly unravel the mystery of the Cryogenic DBB valve.

Cryogenic valves are used in cryogenic fluid systems operating at temperatures ranging from -40°C to -253°C and are crucial in the industrial sector. The cryogenic liquids they transport, such as ethylene and liquid oxygen, are flammable and explosive, expanding hundreds of times in volume when heated and vaporized. Cryogenic valves precisely control the flow and flow of these media, preventing leaks, abnormal pressure increases, and serious accidents like explosions. In equipment such as liquefied natural gas (LNG) and petrochemical exhaust gas separation, they ensure stable system operation. Furthermore, their unique structural design and use of cryogenically resistant materials allow them to adapt to low-temperature environments, extending equipment life and reducing maintenance costs.

Valves come in many varieties, each with its own distinct functions. Choosing the most suitable valve from these diverse arrays poses a challenge for many valve users. This article, using ball valves and butterfly valves as examples, explores which is more practical in real-world applications. This may provide some insight.
