Puka kinipōpōi loko o ka pipeline e hoʻohana nui ʻia e ʻoki, hoʻohele a hoʻololi i ke ala kahe o ka waena.He ʻano valve hou kēia i hoʻohana nui ʻia i nā makahiki i hala iho nei.Loaʻa iā ia nā pono penei:

1. He li'ili'i ke kū'ē o ka wai, a ua like kona koena kū'ē me ka māhele paipu o ka lō'ihi like.

2. Ka hana maʻalahi, ka leo liʻiliʻi, ke kaumaha māmā.

3. Paʻa a hilinaʻi hoʻi, hoʻohana nui ʻia ka mea hoʻopaʻa i ka ʻili o ka pōleʻa i ka plastic, ka hoʻopaʻa ʻana maikaʻi, a ua hoʻohana nui ʻia i ka ʻōnaehana vacuum.

4. E maʻalahi ka hana, wehe a pani koke, mai ka hāmama piha a hiki i ka piha piha e like me ka lōʻihi o ka rotation o 90 °, kūpono no ka mana mamao.

5. Maʻalahi ka mālama ʻana, ʻoi aku ka maʻalahi o ka hoʻonohonoho ʻana i ka pōlele, ʻoi aku ka maʻalahi o ke apo sealing, ʻoi aku ka maʻalahi o ka wehe ʻana a me ka hoʻololi ʻana.

6. Ke wehe piha a pani ʻia paha, ua hoʻokaʻawale ʻia ka ʻili o ka sila a me ka noho valve mai ka waena.I ka hala ʻana o ka waena, ʻaʻole ia e hoʻoheheʻe i ka ʻili o ka valve sealing surface.

7. E pili ana i ka nui o ka nui mai ka liʻiliʻi a hiki i kekahi mau millimeters a hiki i kekahi mau mika, mai ka vacuum kiʻekiʻe a hiki i ke kaomi kiʻekiʻe.

Puka kinipōpōua hoʻohana nui ʻia i ka ʻaila, ka ʻoihana kemika, ka hana mana, ka hana pepa, ka ikehu atomic, ka mokulele, nā rockets a me nā keʻena ʻē aʻe, a me ka People's Daily life.
