ʻO ka hiʻohiʻona mua loa e like mekiwikā poepoeʻo ia ka valve i hoʻopaʻa ʻia e John Warren i ka makahiki 1871. He valve i hoʻonoho ʻia me ka metala me kahi pōpō keleawe a me kahi noho keleawe. Ua hāʻawi hope ʻo Warren i kāna palapala hoʻolālā o ka valve pōpō keleawe iā John Chapman, ke poʻo o Chapman Valve Company. ʻOiai ke kumu, ʻaʻole i hoʻokomo ʻo Chapman i ka hoʻolālā a Warren i ka hana ʻana. Akā, ua hoʻohana ʻo ia a me nā mea hana valve ʻē aʻe i nā hoʻolālā kahiko no nā makahiki he nui.

ʻO nā kiwikā pōpō, i ʻike ʻia hoʻi he mau kiwikā pōpō, ua hoʻokani hope i kahi hana i ka wā o ke Kaua Honua II. I loko o kēia wā, ua hoʻomohala nā ʻenekinia iā ia no ka hoʻohana ʻana i nā ʻōnaehana wahie mokulele koa. Ma hope o ka holomua onā kiwikā poepoei ke Kaua Honua II, ua hoʻopili nā ʻenekinia i nā kiwikā poepoe i nā noi ʻoihana.

ʻO kekahi o nā holomua koʻikoʻi e pili ana i nā kiwikā pōpō i nā makahiki 1950, ʻo ia ka hoʻomohala ʻana o Teflon a me kona hoʻohana ʻana ma hope ma ke ʻano he mea kiwikā pōpō. Ma hope o ka hoʻomohala holomua ʻana o Teflon, ua hoʻokūkū nā ʻoihana he nui e like me DuPont no ke kuleana e hoʻohana iā ia, no ka mea, ua ʻike lākou e hiki iā Teflon ke lawe mai i nā pono mākeke nui. I ka hopena, ua hiki i nā ʻoihana he nui ke hana i nā kiwikā Teflon. He maʻalahi nā kiwikā pōpō Teflon a hiki ke hana i nā sila maikaʻi i ʻelua ʻaoʻao. I nā huaʻōlelo ʻē aʻe, he bidirectional lākou. He pale leak nō hoʻi lākou. I ka makahiki 1958, ʻo Howard Freeman ka mea hana mua e hoʻolālā i kahi kiwikā pōpō me kahi noho Teflon maʻalahi, a ua patent ʻia kāna hoʻolālā.

I kēia lā, ua hoʻomohala ʻia nā kiwikā pōpō ma nā ʻano he nui, me ko lākou kūlike me nā mea a me nā noi hiki. Eia kekahi, hiki iā lākou ke hoʻohana i ka mīkini CNC a me ka papahana kamepiula (e like me ke kumu hoʻohālike Button) e hana i nā kiwikā maikaʻi loa. I ka wā koke, e hiki i nā mea hana kiwikā pōpō ke hāʻawi i nā koho hou aʻe no kā lākou huahana, me ke kūkulu ʻana i ka alumini, ka liʻiliʻi o ke komo ʻana a me nā hiki ke hoʻonui i ka throttling, e ʻae ana i nā mea hoʻohana e hoʻouna i kahi nui o ka wai ma o ka kiwikā ma kahi kahe palena.

ʻO ka pahuhopu o ka valve pōpō ka hoʻoponopono ʻana i ke kahe o ka wai. Hiki iā lākou ke hana i kēia ma nā ʻano he nui. Hiki iā lākou ke hoʻoponopono i kekahi mau ʻano valves kahe haʻahaʻa, hāʻawi i ka pale ʻana i ke kahe hope no nā valves me nā ʻaha nānā swing, hoʻokaʻawale i ka ʻōnaehana, a hāʻawi i ka pani piha no nā mea hoʻohana kia.

Ma muli o ka hiki ke hoʻokele ʻia me ka lima a i ʻole ka uila, hiki i nā kiwikā pōpō ke lawelawe i nā noi me nā ʻano hoʻonohonoho like ʻole.

I ka hapanui o nā hihia, hoʻohana ʻia nā kiwikā pōpō e wehe a pani i nā paipu e loaʻa ana nā mea paʻa i hoʻokuʻu ʻia, nā slurries, nā wai a i ʻole nā ​​​​kinoea. ʻO nā noi ʻē aʻe kahi e hoʻohana pinepine ʻia ai nā kiwikā pōpō e komo pū me nā ʻōnaehana paipu, nā lako, a me nā mea hana ma aneane nā ʻoihana āpau e halihali ana i nā wai. Hiki iā ʻoe ke loaʻa iā lākou ma nā wahi āpau mai ka papahele hale hana a i ka faucet i kou home. Nā ʻoihana e hoʻohana ananā kiwikā poepoee komo pū me ka hana ʻana, ka eli ʻana, ka ʻaila a me ke kinoea, ka mahiʻai, ka hoʻomehana a me ka hoʻoluʻu ʻana, nā paipu ʻoihana a me ka home, ka wai, nā waiwai kūʻai, ke kūkulu ʻana, a pēlā aku
