I ka hoʻokokoke ʻana mai o ke kau hoʻomehana makahiki, e komo ana ʻo NSEN i kahi manawa hana nui i ke kauwela. I ka hoʻomākaukau ʻana no ke kau hoʻomehana o kēia makahiki, ua kau kā mākou mea kūʻai aku i kekahi mau kauoha i ka hopena. Manaʻo ʻia e hana ʻia he 800 mau ʻāpana o nā kiwikā pepeke no ka hoʻomehana ʻana i kēia makahiki. No laila, ua mālama kā mākou hui i ka nui o ke ʻano kuʻi ʻana o ka butt, a me ka flange butterfly valve casting.

Ma lalo nei e hoʻolauna pōkole mākou i nā kiwikā pepeke i hoʻohana ʻia no ka hoʻomehana ʻāpana;

Ua ʻike mākou a pau he mea nui ka lawe ʻana o ka mea hoʻomehana i ka mahu wela kiʻekiʻe a me ka wai wela, no laila e hoʻokaʻawale ʻia ka valve butterfly sila palupalu ke koho ʻia ke koho, a me kakiwikā pepeke i hoʻopaʻa ʻia me ka haopono e koho ʻia. Wahi a ke sila ʻana, ua māhele nui ʻia mākou i ʻelua ʻano, ʻo ke ʻano mua he kiwikā pepeke sila laminated, a ʻo ke ʻano ʻelua he kiwikā pepeke sila metala paʻa. Pono e hoʻoholo ʻia kēia mau ʻano ʻelua o nā hale sila e like me ka mahana a me ka nui o ke kahe o ka mea hana.

Wahi a ke ʻano pili, ʻo nā koi nuikuʻihao hopea meʻano flangeI kēia manawa, hiki iā NSEN ke hāʻawi i nā kūlana pili:

GOST 33259-2015, GOST 12815, EN1092-1, ASME B 16.5/B16.47

Inā makemake ʻoe e ʻike hou aʻe e pili ana i ke ʻano o kēia ʻano valve, e kaomi i ka loulou ma lalo nei
