Ko te Valve Tuarua Tuarua o te Pneumatic he kareti e whakahaere ana i te rere, te pehanga me te pāmahana o te reo i roto i te taputapu pneumatic. Kei a ia nga ahuatanga o te tino kaha o te parenga o te kaha o te pāmahana, te taapiri me te tino tuuturu, a, he nui te whakamahi i te punaha whakahaere o te tipu o te hinu, te umanga matū, me etahi atu ahumahi, me etahi atu ahumahi.
Ko te tirohanga o te raupaparorohiko o te wharau i te pāmahana nui o te wharau pāmahana engari kaore i te waatea ki nga waahanga e whai ake nei:
Te umanga hinu : i whakamahia mo te mana pāpāho pāmahana nui i roto i te hinu me te mahi miihini, te whakamahine, te rokiroki hinu me etahi atu tukanga.
Ahumahi matū : He pai mo te mana o te hunga pāpāho pāmahana tiketike i roto i te mahinga whakaputa matū, penei i te haukini hangai, ki te ahuru me te methanol me etahi atu mahinga whakaputa.
Te Ahuwhenua : I whakamahia mo te mana o te hunga pāpāho pāmahana tiketike i roto i te tukanga o te whakatipuranga mana, penei i te mana boor, te mana turbine, me etahi atu.
Ahumahi metallurgical : He pai mo te whakahaere waenga i te pāmahana nui i roto i te mahi hanga metallurgical, penei i te mahi rino, te mahi maitai me etahi atu mahinga.
Ko ta maatau kamupene hei taapiri i te raorao pāmahana nui-pāmahana, ka puta ano te Vandic Blade Valve, Vand Bardfly Valve, Veumoana Waakau , me etahi atu.
