I-valves yesango zisetyenziselwa ukuvala ukuhamba kwezinto zotywala kunokuba kumiliselo lokuhamba. Xa ivulekile ngokupheleleyo, i-valve yesango eliqhelekileyo engenasithintelo kwindlela yokuhamba, ekhokelela ekuchanyoneni kakhulu kwindlela evulekileyo. Oku kuthetha ukuba inqanaba lokuhamba alitshintshi ngokulinganayo nge-stem hamba. Kuxhomekeka kulwakhiwo, isango elivulekileyo elivulekileyo linokutshabalala ukusuka ekuhambeni kwamanzi.
