ʻO ke kaʻina hana o ka valve pōpō kila kila ma o ka hana ʻana i nā mea kila kila i loko o ke ʻano pōpō, a me ka hoʻohui ʻana i kahi kahawai wai symmetrical ma waenakonu o ka pōpō e hana i ke kino pōpō. ʻO ka maʻamau, ua haku ʻia ia me kahi pōpō, kahi kino valve, kahi noho a me kahi kumu valve.
He ākea loa ka hoʻohana ʻana o nā kiwikā pōpō kila kila. Hiki ke hoʻopili ʻia i ka kaohi ʻana i ke kahe a me ka ʻoki ʻana i nā wai like ʻole, nā kinoea a me nā mahu. Hoʻohana nui ʻia nā kiwikā pōpō kila kila i nā ʻōnaehana pipeline i ka petroleum, kemika, metallurgy, mana uila, lāʻau lapaʻau, meaʻai a me nā ʻoihana ʻē aʻe e kaohi i ke kahe a me ke kuhikuhi o ka medium.
He nui nā pono o ka valve pōpō kila kila. ʻO ka mea mua, he kūpaʻa ka kila kila i ka pala a me ke kūpaʻa wela kiʻekiʻe, kūpono no nā ʻano ʻino like ʻole. ʻO ka lua, he hoʻolālā kū hoʻokahi ka hoʻolālā poepoe a me ka hana sila maikaʻi, hiki ke pale i ka leakage waena a mālama i ka ikaika hana haʻahaʻa. Eia kekahi, he maʻalahi ka valve pōpō kila kila, wikiwiki a maʻalahi ke kuapo, a hiki ke ʻoki koke ʻia ke kahe waena. I ka manawa like, he liʻiliʻi ka valve pōpō kila kila, liʻiliʻi ka nui, maʻalahi ke hoʻouka a mālama, a he ola lawelawe lōʻihi.
ʻO ka hiʻohiʻona kūikawā o ka valve pōpō kila kila ʻo ia ka hana kiʻekiʻe a me ka hoʻolālā like ʻole o kāna mea, e hoʻokō ana i nā pono kaohi o nā pāpaho kūikawā e like me ke kiʻekiʻe o ka mahana a me ka pala. Mālama ia i ka hilinaʻi i nā wahi hana koʻikoʻi a hiki ke hana palekana ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi. Loaʻa i ka valve pōpō kila kila kahi haʻahaʻa o ka leakage, hiki ke hoʻomaikaʻi i ka pono hana a me ka palekana o ka ʻōnaehana pipeline.
