I-viling viles zingasetyenziselwa ukugaya umhlaba wokutywina, i-POVVE CALS, isitulo se-valve kunye nezinye ii-valti zokuqinisekisa ukuba ivili yawo icinyiwe kwaye inxibe i-viels ye-Grinding. kunye nobume kunye nobungakanani bevili lokugaya.
Kumveliso wokuvelisa iveli kunye nokulungisa i-velo, ukukhetha ivili le-valve ye-valve libalulekile kuba ichaphazela ngokuthe ngqo umgangatho wokuqhubekeka kunye nokusebenza kwamacandelo evali. Ke ngoko, ukhetho olufanelekileyo kunye nokusetyenziswa kwamavili okugaya kunokuphucula ukusebenza kakuhle kunye nokwandisa ubomi benkonzo ye-valve, ngelixa uqinisekisa ukuthembeka kunye nokhuseleko lwevali.
