1. Nā hiʻohiʻona o ka hoʻonohonoho ʻana
Aia kekahi mau ʻokoʻa maopopo ma waena o ka valve pulelehua mahele A a me ka valve pulelehua mahele B ma ke ʻano o ke kūkulu ʻana.
1.1 ʻO nā kiwikā pepeke Māhele A he ʻano "concentric", he ʻano maʻalahi kona, nona ke kino kiwikā, ka diski kiwikā, ka noho kiwikā, ke koʻokoʻo kiwikā a me kahi mea hoʻoili. He ʻano diski ke ʻano o ka diski kiwikā a hoʻohuli a puni ke koʻokoʻo kiwikā e kāohi i ke kahe ʻana o ka wai.
1.2 I ka hoʻohālikelike ʻana, ʻo nā kiwikā pepeke mahele B he ʻano "offset", ʻo ia hoʻi ua offset ʻia ke koʻokoʻo mai ka disc, ʻoi aku ka paʻakikī o lākou a loaʻa paha nā sila hou, nā kākoʻo, a i ʻole nā mea hana ʻē aʻe e hāʻawi i ka hana sila a me ke kūpaʻa maikaʻi loa.
2. Henā noi ma nā kūlana hana like ʻole
Ma muli o nā ʻokoʻa o ke ʻano, hoʻopili ʻia hoʻi ka valve butterfly mahele A a me ka valve butterfly mahele B i nā kūlana hana like ʻole.
2.1 Hoʻohana nui ʻia nā kiwikā pepeke Māhele A i ka ʻōnaehana paipu haʻahaʻa haʻahaʻa, ke anawaena nui, e like me ka hoʻokahe wai, ka ea a me nā ʻoihana ʻē aʻe, ma muli o kona ʻano maʻalahi, ka liʻiliʻi, ke kaumaha māmā a me nā hiʻohiʻona ʻē aʻe.
2.2 ʻOi aku ka kūpono o ka valve pulelehua Māhele B no ka noi hana me nā koi hana sila kiʻekiʻe a me ke kaomi waena nui, e like me ka kemika, ka ʻaila, ke kinoea kūlohelohe a me nā ʻoihana ʻē aʻe.
3. Hoʻohālikelike i ka pono o ka hana
3.1 Hana sila: ʻoi aku ka maikaʻi o nā kiwikā pepeke mahele B ma mua o nā kiwikā pepeke mahele A i ka hana sila ʻana, mahalo i ko lākou ʻano paʻakikī a me ka hoʻolālā sila hou aʻe. Hiki i kēia i ka kiwikā pepeke mahele B ke mālama i kahi hopena sila maikaʻi i nā wahi ʻino e like me ke kaomi kiʻekiʻe a me ka mahana kiʻekiʻe.
3.2 Ka mana kahe: He ikaika ka mana kahe o ka valve butterfly mahele A, no ka mea he maʻalahi ka hoʻolālā disk valve, he liʻiliʻi ke kū'ē ʻana o ka hele ʻana o ke wai. Hiki i ka valve butterfly mahele B ke hoʻopilikia i ka pono o ke kahe ʻana o ka wai i kekahi ʻano ma muli o kona ʻano paʻakikī.
3.3 Paʻa: ʻOi aku ka paʻa o nā kiwikā pepeke mahele B, no ka mea, ʻoi aku ka nānā ʻana o kona hoʻolālā kūkulu a me ke koho ʻana i nā mea i ke kūpaʻa lōʻihi a me ke kūpaʻa i ka pala. ʻOiai he maʻalahi ke kūkulu ʻana o ka kiwikā pepeke mahele A, ʻoi aku ka maʻalahi o ka luku ʻia ʻana i kekahi mau ʻano ʻino.
4. Nā hana palekana no ke kūʻai ʻana
I ke kūʻai ʻana i nā kiwikā pepeke mahele A a me ka mahele B, pono e noʻonoʻo ʻia nā mea aʻe:
4.1 Nā kūlana hana: E koho i ka māhele kūpono o ka valve butterfly e like me ko lākou kaomi hana, ka mahana, ka waena a me nā kūlana ʻē aʻe o ka ʻōnaehana pipeline. No ka laʻana, pono e hāʻawi ʻia nā valves butterfly mahele B i ka mea nui i nā wahi kaomi kiʻekiʻe a me nā wahi mahana kiʻekiʻe.
4.2 Nā koi hana: E hoʻomaopopo i nā koi hana, e like me ka mea e pono ai no ka wehe wikiwiki a me ka pani ʻana, ka hana pinepine, a pēlā aku, e koho i ke ʻano o ka valve butterfly kūpono a me ke ʻano hoʻoili.
4.3 Hoʻokele Waiwai: Ma lalo o ke kumumanaʻo o ka hoʻokō ʻana i nā koi o ka hana, e noʻonoʻo i ka hoʻokele waiwai o ka valve butterfly, me nā kumukūʻai kūʻai, nā kumukūʻai mālama, a me nā mea ʻē aʻe, ʻoi aku ka haʻahaʻa o ke kumukūʻai o nā valves butterfly mahele A, ʻoiai ʻoi aku ka maikaʻi o ka hana o nā valves butterfly mahele B, ʻoiai ʻoi aku ka maikaʻi o ke kumukūʻai.
