ʻO ka mea mua, paʻa kona ʻano, liʻiliʻi ka nui, maʻalahi e hoʻouka a mālama. ʻO ka lua, ʻo ka valve ball he hoʻolālā puka piha e hiki ai i ke kahe ke kahe me ka ʻole, e hōʻemi ana i ka poho puʻe a hoʻomaikaʻi i ka pono o ka ʻōnaehana holoʻokoʻa. ʻO ke kolu, hoʻohana ia i ka hoʻolālā pale ahi a me nā mea hiki ke kū i ke kiʻekiʻe kiʻekiʻe a me nā kaiapuni kiʻekiʻe, e hōʻoia ana i ka palekana o ka pūnaewele. Eia kekahi, maikaʻi ka hana hoʻopaʻa ʻana o nā puʻupuʻu pōpō hao, hiki ke pale pono i ka leakage a me ka leak gas phenomena, a hōʻoia i ka hilinaʻi a me ka palekana o ka hana.

Ma waho aʻe o nā hiʻohiʻona a me nā hana i luna, ua loaʻa i ka valve ball gas nā mea maikaʻi aʻe. ʻO ka mea mua, he maʻalahi ka hana a me ka maʻalahi o nā pahu pōpō, koi wale ia i ka rotation o 90 degere i ka hoʻololi ʻana i ka hana, a ʻo ka matrix panina he liʻiliʻi, ʻoihana a maʻalahi. ʻO ka lua, he lōʻihi ke ola o ka ball Valve, hiki i ke ola lawelawe ke piʻi i nā ʻumi tausani o nā pōʻai hāmama, ʻaʻole maʻalahi ke ʻaʻahu, e hōʻemi ana i ke alapine a me ke kumukūʻai o ka hoʻololi a me ka mālama.
