Nui nā pilikia maʻamau me nā valves, ʻoiai nā mea maʻamau e holo ana, holo, a me ka liki ʻana, i ʻike pinepine ʻia ma nā hale hana. ʻO nā ʻeke valve o nā valves maʻamau i hana ʻia me ka rubber synthetic, kahi hana piha maikaʻi ʻole, e hopena ana i ka corrosion nui o ka medium hana, ka mahana a me ke kaomi kūpono ʻole, a pēlā aku; waiho ʻia ka ʻūlū holoʻokoʻa i mālama ʻia, a nui ka friction kūloko; hoʻohana ʻia ka ʻūlū no ka lōʻihi loa. ʻO ka hanana ʻelemakule; hana ikaika loa; ua pala ka ʻōpala o ke kumu valve, a i ʻole ua popo ma muli o ka nele o ka pale ʻana i ka lewa ākea, a pēlā aku, e hana ana i nā pilikia valve.
ʻO ka ʻūlū valve o ka moʻo valve pale-ʻaʻahu i hana ʻia me ka rubber pale-ʻaʻahu kiʻekiʻe, kahi mea kakaikahi no ka leakage. Hoʻohuihui ʻia me kahi liʻiliʻi o nā mea hoʻohui nano-scale a me ka latex kūlohelohe i kahi mokuʻāina pulu (rubber kūlohelohe). ʻOi aku ka maʻalahi o ka hui ʻana i ka waiū i ke mokuʻāina wai), ʻoi aku ka like o ka hui ʻana, a ʻo ka nui o ka rubber kūlohelohe ma kahi o 97%, no laila e mau ana ke kaulahao lōʻihi o nā molekala rubber, a ʻo kona kūpaʻa a me ka elasticity he 10 mau manawa o ka rubber maʻamau, no laila he ikaika ka hana abrasive a kūpono no nā ʻano hana corrosive like ʻole. Loaʻa iā ia ka elasticity kiʻekiʻe a hiki ke hōʻemi i ka friction, no laila hiki ke hoʻohana ʻia no ka manawa lōʻihi. Pono nā pilikia pitting a me ka popo o ke kumu valve i ka pale ʻana i kēlā me kēia lā e nā mea hoʻohana.
Eia kekahi, ʻaʻole maikaʻi ka hana sila o ka valve maʻamau, a ʻaʻole hiki ke kū i ka hopena o ka pāpāho kahe wikiwiki; ʻaʻole pili pono ke apo sila me ka noho valve a me ka pā valve; wikiwiki loa ka pani ʻana, a ʻaʻole pili pono ka ʻili sila; kekahi media, mālie ma hope o ka pani ʻana. ʻO ka hoʻoluʻolu e hana i nā humuhumu maikaʻi ma ka ʻili sila, e hopena ana i ka ʻino a me nā pilikia ʻē aʻe. Hoʻohana ka rubber pale ʻaʻahu i loko o ka valve pale ʻaʻahu i ka ʻenehana vulcanization kiʻekiʻe-pinepine i ka mahana o ka lumi i ka wā o ke kaʻina hana vulcanization, i mea e hoʻomehana ʻia ai ka rubber me ka lalo mānoanoa nui a vulcanized like i loko a i waho i ka manawa like, ʻoi aku ka like o ka vulcanization, ʻoi aku ka maʻalahi o ka ʻili, a ikaika ka ikaika tensile. Kūpaʻa kiʻekiʻe, hiki ke omo, pale i ka hopena, ka friction a me ka hana sila. ʻAʻohe pilikia me ka hana sila, he ʻili maʻemaʻe kona, a ʻaʻole ia e hoʻopili maikaʻi ʻole i ka ʻili sila ma muli o ka pani wikiwiki ʻana.
Aia kekahi mau kumu ʻē aʻe, inā he valve maʻamau a i ʻole he valve pale ʻaʻahu, pono ka mea hoʻohana e lawe i nā hana palekana a me ka hoʻohana maʻamau, e like me: ke anuanu ke aniau, ʻaʻole lawe ka valve i nā hana palekana, e hopena ana i ka hanana haki kino valve; hopena a lōʻihi paha ka huila lima i hōʻino ʻia ma muli o ka hana ikaika o ka lever; ʻo ka ikaika like ʻole i ke kaomi ʻana i ka ʻūlū, a i ʻole ka gland hemahema e haki ai ka gland ʻūlū a pēlā aku.
