Ngomkhiqizo we-NSEN, phumelela ukuhlolwa kofakazi njengoba kuchazwe ku-BS 6364:1984 ejwayelekile yi-TUV. I-NSEN iyaqhubeka nokuletha inqwaba ye-valve ye-butterfly e-cryogenic yokuvala ohlangothini ngalunye.

I-valve ye-Cryogenic isetshenziswa kabanzi embonini ye-LNG. Njengoba abantu benaka kakhulu izinkinga zemvelo, i-LNG, lolu hlobo lwamandla ahlanzekile luyathandwa.

Njengoba izinga lokushisa le-LNG ngaphansi kwengcindezi evamile lingu-162℃, futhi linezici zokusha nokuqhuma, ivalvu yokushisa ye-cryogenic ayigcini nje ngokuhlangabezana nezidingo zokushisa okuphansi kokusetshenziswa, kodwa futhi idinga ukucabangela ukwakheka kokuvikela umlilo. Kungenxa yalezi zidingo ukuthi ukuphepha nokuthembeka kwamavalvu e-cryogenic kuzoba phezulu kunevalvu evamile.

Okubaluleke kakhulu, umzimba wevalvu, ipuleti lebhabhathane, ingxenye yokwelula kanye nezingxenye zangaphakathi kumele kucutshungulwe ngendlela ye-cryogenic ngaphambi kokuqeda ukuze kuqedwe ithonya lokushintsha kwesigaba. Ngaphandle kwalokho, ukuguqulwa kwesigaba se-martensite kuzokwenzeka emazingeni okushisa aphansi, okubangela ukuguqulwa kwevalvu, okuholela ekutheni ivalvu ivuza.

Uhlobo lokuxhumanisa lwalokhu kuthunyelwa yi-flange ne-wafer, kanti izinto zomzimba we-valve ne-disc yi-CF8M. Izinto zokuvala ziseyisakhiwo sendandatho yokuvala eqinile yensimbi, enokuvalwa kwesiqu sokupakisha okuphuma kancane.

Uma unethemba lokufunda okwengeziwe noma ukuthola ikhambi lephrojekthi yakho, wamukelekile ukuxhumana nathi.
