Fixed ball valve installed at ultra-low temperature

The ultra-low temperature upper Ball valve is suitable for working conditions with temperatures up to -196 ℃. The product is widely used in liquefied natural gas, liquefied petroleum gas, air separation, and other low-temperature industries. The ultra-Low Temperature Ball Valve adopts international advanced technology and uses LIP SEAL sealing rings. This type of valve maintains excellent sealing performance in application. This series of upper mounted valves can achieve online maintenance.

Performance characteristics of fixed ball valves installed at ultra-low temperatures

Good low-temperature resistance: capable of stable operation at extremely low temperatures, meeting the transportation and control requirements of low-temperature media such as liquefied natural gas, liquid oxygen, and liquid hydrogen.

Reliable sealing performance: Whether it is a metal hard seal or a soft seal structure, it can achieve good sealing under low temperature and high pressure conditions, with minimal leakage, improving the safety and reliability of the system.

Low fluid resistance: When the sphere is opened, the channel is almost unobstructed, the fluid passes smoothly, and the flow resistance coefficient is small, which is conducive to reducing the energy consumption of the pipeline system.

Easy to operate: The valve can be opened and closed by rotating the ball through the valve stem, with a small operating torque and convenient and fast operation. Multiple driving methods such as manual, worm gear transmission, pneumatic, and electric can be used to meet the needs of different application scenarios.

Application Area 

Mainly used in fields that require the transportation and control of low-temperature media, such as the production, storage, and transportation systems of liquefied natural gas, including LNG receiving stations, LNG tank trucks, LNG refueling stations, etc; Transport and control of low-temperature liquids such as liquid oxygen, liquid nitrogen, and liquid argon in air separation units; Pipeline systems for low-temperature ethylene, propylene and other media in the petrochemical industry; The transportation and control system of rocket propellants in the aerospace field.
