Me ka huahana NSEN e hele i ka hōʻike hōʻike e like me ka maʻamau BS 6364:1984 e TUV.Ke hoʻomau nei ʻo NSEN i ka hāʻawi ʻana i kahi pūʻulu o bi-directional sealing cryogenic butterfly valve.

Hoʻohana nui ʻia ka valve Cryogenic i ka ʻoihana LNG. Me ka nui o ka nānā ʻana o ka poʻe i nā pilikia kaiapuni, LNG, lilo kēia ʻano o ka ikehu maʻemaʻe i makemake ʻia.

No ka mea ʻo ka mahana o ka LNG ma lalo o ke kaomi maʻamau ʻo -162 ℃, a loaʻa iā ia nā hiʻohiʻona o ka flammability a me ka pahū, ʻaʻole hoʻokō ka valve wela cryogenic i nā koi o ka haʻahaʻa haʻahaʻa hoʻohana wela, akā pono pū kekahi e noʻonoʻo i ka hoʻolālā pale ahi.Ma muli o kēia mau koi e ʻoi aku ka kiʻekiʻe o ka palekana a me ka hilinaʻi o nā valve cryogenic ma mua o nā valve maʻamau.

ʻO ka mea nui aʻe, pono e hana cryogenically ka kino valve, butterfly plate, extension part a me nā ʻāpana o loko ma mua o ka pau ʻana e hoʻopau i ka mana o ka hoʻololi ʻana.A i ʻole, e hoʻololi ʻia ka māhele martensite ma nā haʻahaʻa haʻahaʻa, e hoʻoneʻe ana i ka valve deformation, e hopena i ka lele ʻana o ka valve.

ʻO ke ʻano pili no kēia hoʻouna ʻana he flange a me ka wafer, a ʻo ka mea o ke kino valve a me ka disc ʻo CF8M.ʻO ka mea hoʻopaʻa ʻana, ʻo ia nō ka hoʻolālā apo hoʻopaʻa paʻa paʻa metala, me ka hoʻopaʻa haʻahaʻa haʻahaʻa.

Inā manaʻo ʻoe e aʻo hou a loaʻa paha ka hopena no kāu papahana, e ʻoluʻolu e hoʻokaʻaʻike me mākou.
