ʻAno ʻāwīwī ʻaʻole piʻi ʻana o ke kumu lāʻau kūpaʻa noho paʻa puka

Groove type non rising stem elastic seat seal gate valve he 'ano o ka pahe'e sila pahee. He ʻano hou ia o ka huahana valve gate i hana ʻia e ka hoʻokomo ʻana i ka ʻenehana haole. He nui nā mea maikaʻi i loaʻa ʻole i nā valve maʻamau a loaʻa i kahi ākea o nā noi. Loaʻa iā ia nā mea maikaʻi o ka hoʻololi kukui, ka hoʻopaʻa ʻana i ka hilinaʻi, ka hoʻomanaʻo elastic maikaʻi a me ke ola lawelawe lōʻihi. He māmā ke kaumaha o ka puka puka Groove. Hana ʻia ke kino me ka hao nodular, ʻo ia ka mea ma kahi o 20% - 30% ʻoi aku ka māmā ma mua o ka valve puka kuʻuna. He maʻalahi ke hoʻouka a mālama. Hoʻohana nui ʻia i ka wai, ka wai, ka hana ʻana, ka ʻaila, kemika, ka meaʻai, ka lāʻau lapaʻau, ka lole, ka mana, ka hoʻouna ʻana, ka metallurgy, nā ʻōnaehana ikehu a me nā paipu wai ʻē aʻe e like me ka hoʻoponopono ʻana a me nā mea hana intercepting.
