Choyamba, kapangidwe kake kakang'ono, kakulidwe kakang'ono, kuyika kosavuta ndi kukonza. Kachiwiri, valavu ya mpira imagwiritsa ntchito chitseko chokwanira, chomwe chingapangitse kuti kuyenda kusakhale kolepheretsa, kuchepetsa kupanikizika, komanso kupititsa patsogolo kayendetsedwe ka kayendetsedwe kake. Chachitatu, kugwiritsa ntchito kutentha kwakukulu ndi kupanikizika kwakukulu kwa chilengedwe moto chitetezo kapangidwe ndi zipangizo kuonetsetsa chitetezo cha dongosolo. Kuphatikiza apo, ntchito yosindikiza ya valavu ya mpira wa pneumatic ndi yabwino, yomwe imatha kupeŵa bwino kutulutsa mpweya ndi zochitika zowonongeka, ndikuwonetsetsa kudalirika ndi chitetezo cha ntchito.

Kuwonjezera pa zomwe zili pamwambazi ndi ntchito, valve ya mpira wa gasi imakhalanso ndi ubwino wotsatira. Choyamba, ntchito ya valve ya mpira ndi yabwino komanso yosinthika, imangofunika kusinthasintha madigiri 90 kuti musinthe ntchito, ndipo matrix otseka ndi ang'onoang'ono, okwera mtengo komanso abwino. Chachiwiri, valavu ya mpira imakhala ndi moyo wautali, moyo wautumiki ukhoza kufika makumi masauzande nthawi zambiri kuti utsegule kuzungulira, kosavuta kuvala, kuchepetsa mafupipafupi ndi mtengo wosinthira ndi kukonza.

Pamwamba pake ndi chrome-yokutidwa, pamwamba pake ndi yosalala komanso yoyera, ndipo mankhwalawa ndi apamwamba kwambiri.
