Ua komo ka valve puka pahi i Kina i nā makahiki 1980. I loko o 20 mau makahiki, ua hoʻonui ʻia kona laulā noi mai nā kahua maʻamau i kahi ākea o nā ʻoihana, mai ka hoʻomākaukau ʻana i ka lanahu, ka hoʻokuʻu ʻana o ka gangue a me ka hoʻokuʻu ʻana o ka slag o nā mea kanu mana mine a hiki i ka mālama ʻana i ka wai ʻino o ke kūlanakauhale, mai ka hoʻomohala ʻana i ka pipeline ʻoihana maʻamau a hiki i nā ʻōnaehana pipeline ʻoihana e like me ka meaʻai, ke olakino a me ka lāʻau lapaʻau.
ʻO nā ʻano hoʻokele o ka valve puka pahi:
ʻO nā ʻano hoʻokele lima, uila, pneumatic, hydraulic, bevel gear, electro-hydraulic a me pneumatic a me hydraulic. ʻO ke ʻano o ka valve puka pahi: ke kumu e piʻi ana a me ke kumu ʻaʻole e piʻi ana. Nā mea o ka valve puka pahi: hao hoʻolei ʻia, kila hoʻolei ʻia, kila kalapona, kila kila, uhi fluorine, a pēlā aku. Sila valve puka pahi: sila paʻakikī, sila palupalu, sila ʻaoʻao hoʻokahi, sila ʻaoʻao pālua a me nā mea ʻē aʻe.
ʻO ke ʻano hoʻonohonoho pololei ke kumu no ka hana maikaʻi o ka mīkini. Hoʻohana ka valve puka pahi i ka ʻenekinia paʻakikī ma ke ʻano he mea nui no ka pani ʻana a me ka holoi ʻana me ka pale ʻana i ka throttling. I ka manawa like, ua hoʻolālā ʻia me kahi ʻano kūkulu no ka holoi ʻana me ka pale ʻana i ka throttling. Loaʻa iā ia ka hana pālua o ka pani ʻana a i ʻole ka pani ʻana + ka hoʻolōʻihi ʻana, a hiki i kona ola lawelawe ke hiki i 10 mau manawa o ka valve puka pahi metala maʻamau.
Me nā pono o ka liʻiliʻi o ka nui, ke kū'ē ʻana o ke kahe liʻiliʻi, ke kaumaha māmā, ka maʻalahi o ke kau ʻana a me ka wehe ʻana, hoʻoponopono ka valve puka pahi lahilahi i nā pilikia paʻakikī o ke kū'ē ʻana o ke kahe nui, ke kaumaha kaumaha, ke kau ʻana a me ka nui o ka papahele o ka valve puka maʻamau, ka valve puka pālahalaha, ka valve pōpō, ka valve hoʻōki, ka valve hoʻoponopono a me ka valve pepeke. Ma hope o ka puka ʻana o ka valve puka pahi, ua hoʻololi ʻia ka nui o nā valve ʻokiʻoki maʻamau a me nā valve hoʻoponopono. I kēia lā, hoʻohana nui ʻia ka valve puka pahi ma ʻAmelika Hui Pū ʻIa a me Iapana.

ʻO Nortech kekahi o nā mea hana valve ʻoihana alakaʻi ma Kina me ka palapala hōʻoia maikaʻi ISO9001.
