1. Ma keʻano laulā, i ka hoʻoluliluli ʻana, ka hoʻoponopono ʻana i ka mana a me ka pālolo lepo, pono ke kūkulu ʻia e pōkole ka lōʻihi a wikiwiki i ka wehe ʻana a me ka pani ʻana (1/4 kipi). ʻOki haʻahaʻa ke kaomi (ʻokoʻa kaomi liʻiliʻi), paipai ʻia ka valve butterfly.
2. Hiki ke hoʻohana ʻia ka valve butterfly i ka wā e hoʻoponopono ai i ʻelua kūlana, kahi ala haiki, haʻahaʻa ka walaʻau, cavitation a me ka vaporization, kahi liʻiliʻi o ka leakage i ka lewa, a me nā mea abrasive.
3. Ke hoʻohana ʻia ka valve butterfly ma lalo o nā kūlana kūikawā e like me ka hoʻoponopono throttling, ke sila paʻa, a i ʻole ke komo nui ʻana, ka mahana haʻahaʻa (cryogenic), a pēlā aku, pono e hoʻohana i kahi sila metala i hoʻolālā kūikawā ʻia me kahi mea hoʻoponopono ʻekolu-eccentric a pālua paha. ʻO ka valve butterfly i hoʻolaʻa ʻia no ka honua.
4. He kūpono ka valve butterfly centerline no ka wai maʻemaʻe, ka wai ʻino, ka wai kai, ka wai paʻakai, ka mahu, ke kinoea kūlohelohe, ka meaʻai, nā lāʻau lapaʻau, a me ka ʻaila e pono ai ke sila piha, ʻaʻohe hoʻāʻo hoʻokahe kinoea, nā koi ola kiʻekiʻe, a me ka mahana hana o -10℃ ~ 150℃. A me nā ʻano paipu waikawa a me alkali a me nā ʻano ʻē aʻe.
5. ʻO ka valve butterfly eccentric palupalu i sila ʻia he kūpono no ka wehe ʻana a me ka pani ʻana i ʻelua ala a me ka hoʻoponopono ʻana i nā paipu ea a me ka wehe lepo. Hoʻohana nui ʻia ia i nā paipu kinoea a me nā ala wai i ka metallurgy, ka ʻoihana māmā, ka mana uila, a me nā ʻōnaehana petrochemical.
6. ʻO ka uea metala-a-metala e sila ana i ka valve pepeke eccentric pālua e kūpono no ka hoʻomehana kūlanakauhale, kinoea, lako wai a me nā pipelines kinoea, aila, waikawa a me alkali ʻē aʻe, ma ke ʻano he mea hoʻoponopono a me ka throttling.
7. Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he kiwikā hoʻokaʻawale kinoea nui o ka mīkini hoʻokaʻawale kaomi (PSA), hiki ke hoʻohana nui ʻia ka kiwikā pepeke eccentric triple metal-to-metal seal i ka petroleum, petrochemical, chemical, metallurgical, mana uila a me nā ʻoihana ʻē aʻe. He kiwikā puka a he kiwikā kū. He huahana koho maikaʻi.
ʻO Nortech kekahi o nā mea hana valve ʻoihana alakaʻi ma Kina me ka palapala hōʻoia maikaʻi ISO9001.
