Ua hoʻokumu ʻia ʻo Frank Lockwood ma 1977 a aia ʻo ia ma Houston, USA.Loaʻa iā Frank Lockwood ka ʻike valve ākea a me ka ʻike ʻoihana e hāʻawi i nā mea kūʻai aku me ka maikaʻi o ka paipa, nā valves, nā mea pono, nā flanges a me ka hoʻokele papahana, me ka hoʻolālā, automation, QA, etc.
Loaʻa i nā huahana a Frank Lockwood nā pahu hoʻokele uila palekana palekana, nā mea hoʻokele uila hoʻololi, nā kīwaha hoʻokele uila a pēlā aku.

Ua hoʻokumu ʻia ʻo Flotech ma 1961 a ʻo ia ke keʻena nui ma United States.Ke hoʻonui nei ʻo Flotech i kāna mau huahana a me nā lawelawe i nā makahiki ma o ka loaʻa ʻana o nā ʻoihana ʻē aʻe.Ua kūpaʻa ʻo Flotech i ka hāʻawi ʻana i nā mea kūʻai aku me nā ʻano valves hou a me nā hoʻokele, a me nā lawelawe mālama.
Hoʻopili nā huahana i ka pahu pōpō uila, ka valve butterfly, ka valve pneumatic a me nā kiwi ʻokoʻa ʻē aʻe.

Ua hoʻokumu ʻia ʻo DYNAQUIP Controls ma 1935. No nā makahiki ʻoi aku ma mua o 70, ua hoʻolaʻa ʻia lākou i ka hāʻawi ʻana i ka huahana maikaʻi loa a me ka lawelawe mea kūʻai aku no ka ʻaila a me ke kinoea, nā ʻoihana meaʻai a me nā mea inu, etc.ʻO ka lawelawe maʻalahi no ka hoʻokō ʻana i nā pono o nā mea kūʻai aku ʻoihana, noho a me nā mea kūʻai aku.Aia i loko o ka papahana huahana ka pahu pōpō pōleʻa maʻemaʻe, ka valve butterfly aunoa, ka mea hoʻokele maʻalahi a pēlā aku.

ʻO ka Cr-tec Engineering kahi mea hoʻolako i nā kīʻaha uila, pneumatic a me ka manual.Hiki ke hoʻohana ʻia nā huahana no ka mālama ʻana i ka wai.Nā lawelawe no ka aila a me ke kinoea, ka hoʻomaʻemaʻe wai, ka mālama wai inu, nā mea kanu mana, ka hana automation, ka hana moku, etc.
Loaʻa i nā huahana nā pahu pōpō pōleʻa 2-ala, nā kiwi pōlele 3-ʻaoʻao uila, a me nā kiwi uila ʻokoʻa ʻē aʻe.

He hui kaulana ʻo Schneider me nā makahiki he 180 o ka mōʻaukala i hoʻolaʻa ʻia no ka hāʻawi ʻana i nā hoʻonā kūlohelohe a hoʻomau i ka honua.Loaʻa iā Schneider kahi ākea ākea o nā kinikini pōpō uila e hoʻokō i nā pono o kāu ʻoihana like ʻole.
