Olunye uphawu olwahlulayo lweevalvu zebhola ezidadayo kukuguquguquka kwazo ekuphatheni iintlobo ngeentlobo zolwelo, kubandakanywa izinto ezidlekayo nezirhabulayo. Oku kubenza bafaneleke ukusetyenziswa kumashishini afana neoli kunye negesi, ukusetyenzwa kweekhemikhali kunye nokunyangwa kwamanzi, apho amandla okumelana neemeko zokusebenza ezinzima kubaluleke kakhulu. Ulwakhiwo olunqabileyo lweevalvu zebhola ezidadayo luqinisekisa ukuba banokusingatha izicelo eziyimfuneko ngokufanelekileyo, ukubonelela ngokuthembeka kwexesha elide kunye nokusebenza.
Ukongezelela, iivalve zebhola ezidadayo zifumaneka kwizinto ezahlukeneyo, kubandakanywa insimbi engenasici, i-carbon steel kunye ne-alloys ezikhethekileyo, ezenza zihambelane neentlobo ezahlukeneyo zamanzi kunye neendawo zokusebenza. Oku kubhetyebhetye ekukhetheni izinto kwenza kube lula ukwenza iivalvu zebhola ezidadayo ukuze zihlangabezane neemfuno ezithile zeshishini, ukuqinisekisa ukusebenza kakuhle kunye nobomi benkonzo.
Xa kuziwa kulawulo lokuhamba, iivalve zebhola ezidadayo zinokulawula ngokuchanekileyo nangokufanelekileyo ukuhamba kwamanzi, zizenze zilungele izicelo ezifuna ulawulo oluchanekileyo lokuhamba. Uyilo lwevalve yebhola edadayo lubonelela ngendlela egudileyo kwaye engathintelwanga, ukunciphisa uxinzelelo kunye nesiphithiphithi, kunceda ukuphucula ukusebenza kakuhle kwamandla kunye nokusebenza kwenkqubo iyonke.
Ngokubanzi, ukuguquguquka, ukuthembeka, kunye nokusebenza kakuhle kweevalve zebhola ezidadayo kubenza babe yi-asethi exabisekileyo kwiinkqubo ezahlukeneyo zoshishino. Ingaba ilawula ukuhamba kweekhemikhali ezitshabalalisayo, ukulawula ukuhamba kwegesi ephezulu, okanye ukulawula ulwelo lwenkqubo kwiindawo ezifunayo, iivalve zebhola ezidadayo ziyaqhubeka nokubonisa ukubaluleka kwazo njengolawulo oluthembekileyo kunye nesisombululo solawulo.
Isishwankathelo, ukuguquguquka kunye nokusebenza kweevalvu zebhola ezidadayo kuzenza zibe yinto eyimfuneko kwiindawo ezahlukeneyo zeshishini. Ukukwazi kwabo ukugcina isitywina esiqinileyo, ukumelana neemeko ezinzima kunye nokubonelela ngolawulo oluchanekileyo lokuhamba kubenza babe ukhetho oluthembekileyo kumashishini afuna isisombululo esisebenzayo, esithembekileyo sokusingatha ulwelo. Ngerekhodi layo eliqinisekisiweyo kunye nokuqhubela phambili okuqhubekayo kuyilo kunye nezixhobo, iivalvu zebhola ezidadayo ziya kuqhubeka nokudlala indima ephambili kulawulo lokuhamba kweshishini kwiminyaka ezayo.
