Oku kuzenza zifaneleke ukusetyenziswa kumashishini afana neoyile negesi, ukucubungula iikhemikhali kunye nonyango lwamanzi, apho ukukwazi ukumelana neemeko zokusebenza ezinzima kubalulekile. Ukwakhiwa okuqinileyo kweevalvu zebhola ezidadayo kuqinisekisa ukuba ziyakwazi ukusingatha izicelo ezifuna amandla ngokufanelekileyo, zibonelela ngokuthembeka nokusebenza ixesha elide.
Ukongeza, iivalvu zebhola ezidadayo ziyafumaneka kwiindidi ezahlukeneyo zezinto, kuquka intsimbi engatyiwayo, intsimbi yekhabhoni kunye nee-alloys ezikhethekileyo, nto leyo eyenza ukuba zihambelane neentlobo ezahlukeneyo zolwelo kunye neendawo zokusebenza. Olu bhetyebhetye ekukhetheni izinto lwenza kube nokwenzeka ukwenza ngokwezifiso iivalvu zebhola ezidadayo ukuze zihlangabezane neemfuno ezithile zoshishino, ukuqinisekisa ukusebenza kakuhle kunye nobomi benkonzo.
Xa kufikwa kulawulo lokuhamba kwamanzi, iivalvu zebhola ezidadayo zinokulawula ukuhamba kwamanzi ngokuchanekileyo nangokufanelekileyo, nto leyo ezenza zifaneleke ukusetyenziswa ezifuna ulawulo lokuhamba kwamanzi oluchanekileyo. Uyilo lwevalvu yebhola edadayo lubonelela ngendlela yokuhamba kwamanzi egudileyo nengenamida, lunciphisa ukuhla koxinzelelo kunye nokuxinana kwamanzi, nto leyo enceda ekuphuculeni ukusebenza kakuhle kwamandla kunye nokusebenza kwenkqubo iyonke.
Lilonke, ukuguquguquka, ukuthembeka, kunye nokusebenza kakuhle kweevalvu zebhola ezidadayo kuzenza zibe yimpahla exabisekileyo kwiindlela ezahlukeneyo zokusebenza kwemizi-mveliso. Nokuba kukulawula ukuhamba kweekhemikhali ezidala umonakalo, ukulawula ukuhamba kwegesi enoxinzelelo oluphezulu, okanye ukulawula ulwelo lwenkqubo kwiindawo ezifuna amandla, iivalvu zebhola ezidadayo ziyaqhubeka nokubonakalisa ukubaluleka kwazo njengesisombululo esithembekileyo sokulawula nokulawula ulwelo.
Ngamafutshane, ukuguquguquka nokusebenza kweevalvu zebhola ezidadayo kuzenza zibe yinxalenye ebalulekileyo kwiindawo ezahlukeneyo zoshishino. Ukukwazi kwazo ukugcina uphawu oluqinileyo, ukumelana neemeko ezinzima kunye nokubonelela ngolawulo oluchanekileyo lokuhamba kwamanzi kuzenza zibe lukhetho oluthembekileyo kumashishini afuna izisombululo zokuphatha ulwelo ezisebenzayo nezithembekileyo. Ngerekhodi yazo eqinisekisiweyo kunye nokuqhubela phambili okuqhubekayo kuyilo kunye nezixhobo, iivalvu zebhola ezidadayo ziya kuqhubeka nokudlala indima ebalulekileyo kulawulo lokuhamba kwamanzi zoshishino kwiminyaka ezayo.
