Pali mavuto ambiri omwe amapezeka ndi ma valve, makamaka omwe amawoneka akuthamanga, kuthamanga, ndi kutuluka, zomwe nthawi zambiri zimawoneka m'mafakitale. Manja a ma valve a ma valve ambiri nthawi zambiri amapangidwa ndi mphira wopangira, womwe umakhala ndi vuto losakwanira bwino, zomwe zimapangitsa kuti pakhale kuwononga kwambiri kwa sing'anga yogwirira ntchito, kutentha kosayenera ndi kupanikizika, ndi zina zotero; kulongedza konseko kumayikidwa posungira, ndipo kukangana kwamkati kumakhala kwakukulu; kunyamula kumagwiritsidwa ntchito kwa nthawi yayitali. Kukalamba chodabwitsa; opareshoni ndi yaukali kwambiri; tsinde la valavu lapanga dzimbiri, kapena dzimbiri chifukwa chosowa chitetezo panja, ndi zina zotero, zomwe zimayambitsa mavuto a valve.
Mavavu amtundu wa ma valve osamva kuvala amapangidwa ndi mphira wosamva kuvala kwambiri, womwe ndi wosowa kuti utsike. Zimasakanizidwa ndi zowonjezera zochepa za nano-scale ndi latex yachilengedwe mumkhalidwe wonyowa (rabala wachilengedwe). Mkaka ndi wosavuta kusakaniza mu madzi amadzimadzi), kusakaniza kumakhala kofanana, ndipo zomwe zili mu mphira wachilengedwe zimakhala pafupifupi 97%, kotero kuti unyolo wautali wa mamolekyu a mphira umakhalabe wosasunthika, ndipo kukana kwake ndi kutayika kwake kumakhala nthawi 10 kuposa mphira wamba, kotero iye Imakhala ndi magwiridwe antchito abrasive ndipo ndiyoyenera pazofalitsa zosiyanasiyana zowononga ntchito. Lili ndi elasticity kwambiri ndipo limatha kuchepetsa kukangana, kotero lingagwiritsidwe ntchito kwa nthawi yaitali. Mavuto a phula ndi dzimbiri la tsinde la valve amafuna chitetezo cha tsiku ndi tsiku ndi ogwiritsa ntchito.
Kuonjezera apo, ntchito yosindikiza ya valve yowonjezera si yabwino, ndipo sikungathe kupirira zotsatira za mauthenga othamanga kwambiri; mphete yosindikizira siyikugwirizana kwambiri ndi mpando wa valve ndi mbale ya valve; kutsekedwa kumathamanga kwambiri, ndipo malo osindikizira sakugwirizana bwino; zofalitsa zina, pang'onopang'ono pambuyo kutseka. Kuziziritsa kumapangitsa kuti pakhale zotsekera bwino pamwamba, zomwe zimapangitsa kukokoloka ndi mavuto ena. Rabara yosamva kuvala mu valavu yosamva kuvala imagwiritsa ntchito ukadaulo wapamwamba kwambiri wa vulcanization kutentha kutentha panthawi ya vulcanization, kotero kuti mphira wokhala ndi pansi wandiweyani umatenthedwa ndikuwotchedwa mofanana mkati ndi kunja nthawi yomweyo, vulcanization ndi zambiri yunifolomu, pamwamba ndi yosalala, ndi kumangika mphamvu ndi wamphamvu. Kukhazikika kwakukulu, kumatha kuyamwa, kuthamangitsa kukhudzidwa, kukangana ndi ntchito yosindikiza. Palibe vuto ndi ntchito yosindikiza, imakhala ndi malo osalala, ndipo sizimayambitsa kukhudzana kosindikizidwa bwino chifukwa cha kutseka mofulumira kwambiri.
Palinso zifukwa zina, kaya ndi valve wamba kapena valavu yosamva kuvala, wogwiritsa ntchito amayenera kutenga njira zodzitetezera komanso kugwiritsa ntchito moyenera, monga: nyengo ikazizira, valavu sitenga njira zodzitetezera, zomwe zimapangitsa vuto la valavu yosweka; kukhudza kapena kutalika Bwalo lamanja lawonongeka chifukwa cha ntchito yachiwawa ya lever; mphamvu yosagwirizana pamene mukukankhira kulongedza, kapena chithokomiro chosalongosoka chimapangitsa kuti gland yonyamula katundu ithyoke ndi zina zotero.
