Ukuze uqonde isimiso sokusebenza sevalvu yebhola, kubalulekile ukwazi izingxenye ezi-5 eziyinhloko zevalvu yebhola kanye nezinhlobo ezimbili zokusebenza ezahlukene. Izingxenye ezi-5 eziyinhloko zingabonakala kumdwebo wevalvu yebhola kuMfanekiso 2. Isiqu sevalvu (1) sixhunywe ebholeni (4) futhi siqhutshwa ngesandla noma siqhutshwa ngokuzenzakalelayo (ngogesi noma ngomoya). Ibhola lisekelwa futhi livalwe yisihlalo sevalvu yebhola (5) futhi ama-o-rings awo (2) azungeze isiqu sevalvu. Konke kungaphakathi kwendlu yevalvu (3). Ibhola linembobo edlula kulo, njengoba kuboniswe ekubukeni kwesigaba kuMfanekiso 1. Lapho isiqu sevalvu siphendulwa ngekota, imbobo ivulekele ukugeleza okuvumela imidiya ukuthi idlule noma ivalwe ukuvimbela ukugeleza kwemidiya.
