O va'a polo cryogenic ma pulou fa'alautele e talafeagai mo le fa'aogaina i le vevela e maualalo ifo i le -196°C ua fa'apitoa e fa'atautaia tulaga ogaoga o talosaga cryogenic.O nei valve e masani ona faʻaaogaina i alamanuia e pei o le LNG (liquefied natural gas) faʻagasologa, gaosiga o kesi fale gaosi oloa, ma isi mea e faʻaogaina ai le vai cryogenic. O mea taua o valve polo cryogenic ma pulou faʻalautele mo le -196 ° C e aofia ai: Mea Maualalo: Le valve e masani lava ona fausia mai mea faʻapitoa e pei o le uʻamea uʻamea, carbon steel, poʻo isi uʻamea ma mea e maualalo le vevela e faʻamautinoa ai le faʻatinoga ma le faʻamaoni i totonu o siosiomaga cryogenic. Faʻalauteleina o le Ponaivi Fuafuaga: O le pulou faʻalautele e maua ai le faʻapipiʻi faaopoopo ma le puipuiga mo le vaʻa ma le faʻapipiʻiina. ia fa'atumauina le fa'agaioiga lelei i le vevela sili ona maualalo. Fa'amaufa'ailoga ma le Fa'aputuina: O vaega fa'amaufa'ailoga a le valve ma le fa'apipi'iina o lo'o fa'atulagaina fa'apitoa ina ia tumau lelei ma fetuutuunai i le vevela o le cryogenic, e mafai ai ona tapunia mau ma puipuia le leakage.Su'ega ma Tausi: O nei va'a e faia ni su'ega malosi faʻamautinoa le faʻatinoga ma le tausisia o tulaga faʻapitoa mo le cryogenic service.Opertional Safety: Cryogenic ball valves with extended bones e taua tele mo le faatumauina o le saogalemu ma le faʻalagolago i le pulea o le tafe o le vai cryogenic, e fesoasoani i le saogalemu o le faagaoioiga i le cryogenic systems.When filifilia cryogenic polo valves mo -196° C talosaga, e taua le mafaufau i mea e pei o mea e fetaui lelei, mamafa ma fua o le vevela, ma le tausisia o tulaga ma tulafono faatonutonu talafeagai.
API 6D trunnion polo valve o se oloa valve polo e fetaui ma manaoga o le American Petroleum Institute standard API 6D.O lenei tulaga e faʻamaonia ai le mamanu, meafaitino, gaosiga, asiasiga, faʻapipiʻiina ma le tausiga o manaʻoga o le API 6D trunnion ball valves e faʻamautinoa ai le lelei ma le faʻamaoni o valve polo, ma e talafeagai mo faʻalapotopotoga eseese e pei o le suauu ma le kesi.O vaega ole API 6D trunnion ball valve e aofia ai:
1. E faʻaaogaina le polo atoa e faʻaitiitia ai le paʻu o le paʻu o le valve ma faʻaleleia le gafatia o le tafe.
2.O le valve faʻaaogaina se faʻamaufaʻailoga e lua-auala faʻatasi ai ma le lelei faʻamaufaʻailoga.
3.O le valve e faigofie ona faʻaogaina ma lamolemole, ma o le au e faʻailogaina mo le faigofie ona faʻamaonia e le tagata faʻaoga.
4.O le nofoa valve ma le mama faʻamaufaʻailoga e faia i le maualuga o le vevela, maualuga o le mamafa ma mea e faʻafefeteina, e talafeagai mo faʻasalalauga eseese.
5. O vaega o le valve polo e vaʻaia lelei, faigofie ona faʻapipiʻi ma tausia.API 6D trunnion polo valves e talafeagai mo taimi i totonu o fale gaosi oloa e manaʻomia le pulea o le tafe o le vai, tipi ese le vai, ma faʻamautu le faʻamautu o le mamafa, e pei o le paipa vai i totonu o le suauu, vailaʻau, kesi masani, vai togafitiga ma isi fanua.
