Price of ultra-low temperature eccentric butterfly valve

The ultra-low temperature eccentric butterfly valve is suitable for working conditions with temperatures up to -196 degrees Celsius. It adopts a stuffing box lifting structure and can be designed as an upper structure. The product is widely used in liquefied natural gas, liquefied petroleum gas, air separation, and other low-temperature industries.

Performance characteristics of ultra-low temperature eccentric butterfly valve

Good sealing performance: Through special structural design and material selection, such as the wedge effect of the three eccentric structure, the combination of elastic sealing rings and elliptical sealing surfaces, it can effectively prevent leakage caused by thermal expansion and contraction due to temperature changes, and still ensure good sealing performance at low temperatures.

Low torque operation: Adopting a frictionless and low torque eccentric structure design, the torque does not increase at low temperatures, making the opening and closing operation of the valve easier and more flexible, reducing the load on the driving device.

Corrosion resistance: The selected materials such as stainless steel have good corrosion resistance and are suitable for some low-temperature and corrosive media.

Application Area 

Mainly used in liquefied petroleum gas, liquefied natural gas industrial gas, refrigerated logistics pipeline industry, and industrial demand places below -196 ℃, such as natural gas liquefaction equipment, air separation equipment, pressure swing adsorption equipment and other low-temperature devices in the chemical industry.
