Koho ʻia ka valve pōlele noho metala no ke ʻano hana koʻikoʻi e like me nā ʻāpana paʻa, abrasive, kiʻekiʻe kiʻekiʻe a i ʻole ka papa kiʻekiʻe o ke kaomi ʻana a i ʻole me kekahi o ke kūlana i ʻōlelo ʻia i hui pū ʻia, pipeline maʻamau e like me ke kinikona lanahu, pulp & pepa a me ka ʻaila ʻaila refinery etc.The QL metala noho poepoe valve hōʻike maikaʻi sealing hana, lōʻihi manawa lawelawe, haʻahaʻa torque a comparatively emi puʻe poho ma luna o ka lawelawe.ʻAʻole hiki i ka valve maʻamau e like me ka honua a me ka valve puka ke hoʻokō i kēlā ʻano hana, no laila ke ulu nei ka pahu pōlele noho metala e koi hou aku no ka lawelawe koʻikoʻi.
- ARAN kiʻekiʻe hana metala noho poepoe kiwikā i ka metala-i-metala sila ma waena o nā noho a me ka poepoe o ka hui puila.

- ● Haʻahaʻa wela 'ano metala noho poepoe kiwikā, ka mea wela wela a hiki i -196 ℃ , ke kino kiwikā a me nā māhele o loko e mālama 'ia e -196 design degere wai naikokene haʻahaʻa wela cryogenic lapaʻau, a me ka kiwikā hoʻolōʻihi stem bonnet e hōʻoia i ka kiwikā ua hoʻohana 'ia. ma kahi lawelawe wela haʻahaʻa haʻahaʻa, ʻaʻole ka helu leakage valve.
- ● ʻO ke ʻano wela kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka mahana wela e like me 540 ℃, ua hana ʻia ke kino valve a me nā ʻāpana i loko o ke kila kila kūikawā kūpaʻa kiʻekiʻe ma hope o ka hoʻomaʻamaʻa kūikawā, a hoʻolōʻihi ʻia ke kumu valve me ka hoʻoheheʻe wela ma lalo e hōʻoia i ka hoʻohana maʻamau i ke kiʻekiʻe. lawelawe wela, a ʻo ka hana ʻana o ka valve he zero leakage.
- Hoʻohana nui ʻia ʻo ARAN Metal Seated Ball Valves no nā kūlana lawelawe koʻikoʻi e like me ke kiʻekiʻe corrosion a me ka erosion kaʻina wai me nā ʻāpana paʻa a me ke kiʻekiʻe kiʻekiʻe a i ʻole ke kaomi kiʻekiʻe, ʻo ia mau kūlana ʻaʻole hiki ke lōʻihi ka pahū pōlele noho ma muli o ka ʻokoʻa o ka noho.Ma ke noi noiʻi, he mea nui ka ʻike o ka valve medium a me ka mahana no ka ʻenekini kūʻai QL e koho i ke ʻano hoʻohālike kūpono.
