Design Feature
1.All valve parts whose service temperature is less than -100°C shall be cryogenically treated in accordance with relevant regulations to prevent low-temperature brittleness of the material and volume change caused by phase change of the material at cryogenic temperature.
2.The long neck structure is adopted to make the packing work temperature above 0℃, effectively preventing the packing from reducing the sealing performance or even sealing failure due to the low working temperature, and it is convenient to wrap the valve with insulation material to prevent the loss of cold energy.
3.The floating ball valve adopts the inlet pressure relief outlet seal design, which effectively prevents the abnormal pressure rise in the middle cavity caused by temperature changes, and ensures the safe operation of the valve and pipeline.
