I-valve yesango licandelo elisisiseko leenkqubo zokulwa umlilo, idlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi. Iyenzelwe ngokukodwa ukuthintela okanye ukuvumela ulwelo ukuba luhambe ngokusebenzisa isango okanye i-quals okanye ivula indlela yendlela. Olu hlobo lwevalve lusetyenziswa ngokubanzi kumashishini ahlukeneyo ukulawula ukuhamba kolwelo, kubandakanya namanzi, ioyile kunye negesi.
Kwimeko yokulwa umlilo, i-valve yesango kubalulekile ukuze bakwazi ukulawula ukuhanjiswa kwamanzi. Eyona njongo iphambili yezi valves kukukhetha icandelo lombhobho okanye uvale iindawo ezithile ukuqulatha umlilo. I-valve yesango inokuyeka ngokuphumelelayo kwamanzi ukusuka ekuboneleleni okuphambili, ukuthintela nakuphi na ukuvuza okanye inkcitho kwaye ikhokelele kwindawo yomlilo.
Uyilo lwe-valve yesango ibandakanya isango leflethi okanye elinemigca elinyukayo linyuka phakathi kwezihlalo ezimbini ezifanayo, ezidala ukuhamba komgca othe tye. Xa ivalve ikwindawo evaliweyo, isango litywina ngokupheleleyo isicatshulwa, lithintela nawuphi na amanzi ekugqityweni. Kwelinye icala, xa ivuliwe iveni, isango likhutshiwe, livumela amanzi ukuba ahambe ngokukhululekileyo.
Enye yenzuzo ebalulekileyo ye-valve yesango kukukwazi kwayo ukubonelela ngokuvulwa okugcweleyo, okuthetha ukuba iphazamiseke kakhulu ukuhamba xa ivulekile xa ivulekile. Olu phawu luqinisekisa inqanaba eliphezulu lokuhamba kunye noxinzelelo, olubalulekileyo kwiimeko zokulwa komlilo apho inani ngalinye loxinzelelo.
I-vilves yesango iyahlala ihleli kwaye ithembekile, ibenze balungele iinkqubo zokulwa umlilo. Zenzelwe ukumelana noxinzelelo oluphezulu kunye nobushushu, ukuqinisekisa ukuba banokuphatha iimeko zomsebenzi ezinamandla zihlala zidibana ngexesha lokunyanzelwa komlilo. Ukongeza, iindawo zesango azinyangeki ekubonakalisweni, okuphucula ubumnene.
Ukuqukumbela, i-valve yesango idlala indima ebalulekileyo kwiinkqubo zokulwa umlilo ngokulawula ukuhamba kwamanzi. Bahlula ngokukuko kwamacandelo emibhobho, bavumela amanzi ukuba abhekiswe ngqo apho ifuneka khona uninzi ngexesha likaxakeka lomlilo. Ukuvula kwabo ngokupheleleyo kuqinisekisa ukuba ubuninzi benqanaba lokutyalo kunye noxinzelelo, ngelixa ukuqina kwabo kunye nokuchasana nokuzilolonga kubenze babe nezinto ezinokuthenjwa. Xa kufikwa kumlilo, iivils zesango zizinto ezingenakuphikwa ezikwenza ukuba iimbonakalo zomlilo zidibanise imililo ngokufanelekileyo nangokufezekileyo.
