Ngenkqubela phambili eqhubekayo yesayensi kunye netekhnoloji kunye nokwandiswa okuqhubekayo kweesiza zesicelo, ithemba lesicelo le-canoid ye-boleloid ibanzi ngakumbi kwaye ibanzi ngaphezulu. Kwintsimi ye-aerospace, colvesvenoid i-valve isetyenziselwa ukulawula iinkqubo ezibalulekileyo ezinjengokuhambisa amafutha kunye neenkqubo ze-hydralic zenqwelomoya ukuqinisekisa ukhuseleko lwenqwelomoya. Kwizixhobo zomkhosi, ii-boleloid i-valls zisetyenziselwa ukulawula iinkqubo zenkqubo, iinkqubo ze-hydraulic, njl., Ukuphucula ukusebenza kwezixhobo zokulwa. Ukongeza, kwicandelo lamandla, umzi-mveliso wekhemikhali kunye nokukhuselwa kwendalo, imithwalo yevalloid, i-bolenoid idlala indima ebalulekileyo ekulawuleni ukuhamba kwemibhobho yeoyile kunye negesi kunye nokulawula ukusasazwa kwamanzi. Ezi zicelo azibonakali nje iyantlukwano kunye nokuguquguquka kwe-coilnoid coil, kodwa zibonisa imeko yayo ebalulekileyo kwishishini lemizi-mveliso nezentlalo.
