Tiyo pòtay yo itilize yo fèmen koule nan likid olye ke pou règleman koule.Lè konplètman louvri, valv la tipik pòtay pa gen okenn obstak nan chemen an koule, sa ki lakòz rezistans koule ki ba anpil. Gwosè a nan chemen an koule louvri jeneralman varye nan yon fason ki pa lineyè kòm pòtay la deplase.Sa vle di ke to koule a pa chanje respire ak vwayaj tij.Tou depan de konstriksyon an, yon pòtay ki pasyèlman louvri ka vibre soti nan koule likid la.
