Kubera ko ntarinze kwitondera cyane valve isubira inyuma mu gihingwa cyo kuvanga Asfalt mbere, ntabwo mfite kirengera kunanirwa kw'iki gikoresho. Mubyukuri, kunanirwa kwa valve isubira inyuma ntabwo bigoye cyane. Igihe cyose ubizi bike kuri yo, uzamenya rwose uko nabikemura?

Hariho kandi impanuka mu bimera bya ashalt, kandi kunanirwa kwayo ntakindi kirenze ibibazo bisanzwe nkibi, imirongo ya gazi, hamwe na electromagneic felot yindege. Birumvikana ko ibitera n'ibisubizo bihuye n'ibitekerezo bitandukanye nabyo biratandukanye. Kuberako ibintu byahinduwe kuva kera, benshi muribo biterwa no guhinda umukene wa valve, komeza amasoko yangiritse, nibindi, birakenewe kugenzura imiterere yigikoresho cya peteroli hamwe na bettle yamavuta yo gusiga. Niba hari ikibazo, amavuta yo gusiga cyangwa ibindi bice birashobora gusimburwa. Nyuma yigihingwa cya asfalt cyakoraga igihe kirekire, valve yahinduye valve ikunda kwambara ipantaro ya valve, ibyangiritse kuri valve nintebe ya valve nintebe ya valve, biganisha kuri gaze kuri valve. Muri iki gihe, inzira nziza kandi nziza yo guhangana nayo ni ugusimbuza impeta yikirango, valve stem nintebe ya valve, cyangwa gusimbuza itaziguye ihinduka kugirango utsinde ikibazo cyo guhinduranya.
