Ivalve yesango licandelo elisisiseko leenkqubo zokucima umlilo, edlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi. Yenzelwe ngokukodwa ukukhusela okanye ukuvumela ulwelo ukuba luhambe ngokusebenzisa isango okanye i-wedge evimbela okanye evula indlela. Olu hlobo lwevalvu lusetyenziswa kakhulu kumashishini ahlukeneyo ukulawula ukuhamba kolwelo, kubandakanywa amanzi, ioyile kunye negesi.
Kwimeko yokulwa nomlilo, iivalve zesango ziyimfuneko kwikhono labo lokulawula ukunikezelwa kwamanzi. Eyona njongo iphambili yezi zivalo kukwahlula amacandelo ombhobho okanye ukuvala iindawo ezithile ukuze kuthintelwe umlilo. Ivalve yesango inokunqanda ngokufanelekileyo ukuhamba kwamanzi kubonelelo oluphambili, ukuthintela nakuphi na ukuvuza okanye ukumoshakala kunye nokuya ngqo kwindawo yomlilo.
Uyilo lwevalve yesango lubandakanya isango elisicaba okanye elicinyiweyo elinyuka lisihla phakathi kwezihlalo ezibini ezinxuseneyo, nto leyo eyenza umgca othe tye. Xa i-valve ikwindawo evaliweyo, isango livala ngokupheleleyo i-passage, ukukhusela nayiphi na i-fluid ukuba idlule. Ngokuchasene noko, xa ivalve ivuliwe, isango liyatsalwa, livumela amanzi ukuba ahambe ngokukhululekileyo.
Enye yeenzuzo ezibalulekileyo zevalve yesango kukukwazi ukubonelela ngokuvuleka okugcweleyo, okuthetha ukuba inokumelana okuncinci kakhulu ukuhamba xa ivuleke ngokupheleleyo. Olu phawu luqinisekisa izinga lokuhamba kunye noxinzelelo oluphezulu, olubalulekileyo kwiimeko zokulwa nomlilo apho yonke isibini kunye noxinzelelo lwamanzi lubala.
Iivalve zamasango nazo zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Zenzelwe ukumelana noxinzelelo oluphezulu kunye nobushushu, ukuqinisekisa ukuba ziyakwazi ukujongana neemeko ezinzima zokusebenza ezihlala zidibana nazo ngexesha lemizamo yokucima umlilo. Ukongezelela, iivalve zesango ziyakwazi ukumelana nokubola, nto leyo ephucula ngakumbi ubomi babo obude.
Ekugqibeleni, iivalve zesango zidlala indima ebalulekileyo kwiinkqubo zokulwa nomlilo ngokulawula ukuhamba kwamanzi. Bawahlulahlula ngokufanelekileyo amacandelo emibhobho, evumela amanzi ukuba alathiswe ngokuchanekileyo apho afuneka khona kakhulu ngexesha likaxakeka lomlilo. Ukuvulwa kwabo okugcweleyo kuqinisekisa ubuninzi bezinga lokuhamba kunye noxinzelelo, ngelixa ukuqina kwabo kunye nokuchasana nokubola kubenza babe ngamacandelo athembekileyo. Xa kuziwa ekulweni umlilo, iivalvu zesango zizixhobo eziyimfuneko ezenza abacimi-mlilo bakwazi ukulwa nemililo ngokufanelekileyo nangempumelelo.
