With NSEN product pass the witness test as per standard BS 6364:1984 by TUV. NSEN continue to delivery a batch of bi-directional sealing cryogenic butterfly valve.

Cryogenic valve is widely applied in LNG industry.With people pay more and more attention to environmental issues, LNG ,this kind of clean energy become favored.

Since the temperature of LNG under normal pressure is -162℃, and it has the characteristics of flammability and explosion, the cryogenic temperature valve not only meets the requirements of low temperature use temperature, but also needs to consider fire protection design. It is precisely because of these requirements that the safety and reliability of cryogenic valves will be higher than ordinary valves.

More importantly, the valve body, butterfly plate, extension part and internal parts must be cryogenically processed before finishing to eliminate the influence of phase change. Otherwise, martensite phase transformation will occur at low temperatures, causing valve deformation, resulting in The valve is leaking.

The connection type for this shipment is flange and wafer, and the material of the valve body and disc is CF8M. The sealing material is still all metal solid sealing ring design, with low emission packing stem sealing.
