Iivalvu zebhola zidlala indima ebalulekileyo kubomi bemihla ngemihla njengoko zisetyenziswa yonke imihla njengeebhayisekile okanye iimoto, iinqwelomoya zejethi okanye nakweliphi na ishishini. Iivalvu ziza ngobukhulu obuhlukeneyo kunye neemilo, kwaye ivalve nganye inobukhulu obahlukileyo, umsebenzi, kunye nesicelo.

Ishishini lisebenzise kakhuluiivalve zebhola, kunye nokuqinisekisa ukuba ezi zivalo zihlala zisebenza ngexesha lokusebenza, kukhuselekile ukuzigcina ngaphambi kokuba zidle. Ukucocwa rhoqo kunye nokuthambisa ukuqinisekisa ukusebenza kakuhle kungundoqo kubomi bayo obude.
Ezi zivalo zifumaneka kwimizimba emihlanu yenjongo jikelele, kubandakanywa imizimba eneziqwenga ezintathu, imizimba eneziqwenga ezibini, i-single-body top-entry, i-split-body, kunye ne-welded.iivalve. Ezi mpawu zilandelayo zibenza babe lolona khetho lubalaseleyo lokulawula usetyenziso olwahlukeneyo, kwaye ngamanye amaxesha bagqithisa nasiphi na esinye isivalo esinolawulo oluncinci kwizicelo zokubetha.

Izinto eziluncedo kwiivalvu zebhola

Banikezela ngeenkonzo zokuqinisekisa ukuvuza,
ukuvula nokuvala ngokukhawuleza,
Xa kuthelekiswa neevalvu zesango, zincinci kakhulu ngobukhulu,
Xa kuthelekiswa neevalvu zesango, zikhaphukhaphu,
Isango okanye iivalvu zeglowubhu azinakho ukuguquguquka koyilo oluninzi, ngoko ke kunciphisa inani leevalvu ezifunekayo,
Zenziwe ngobungakanani obahlukeneyo kunye neemilo, ezi zivalo zibonelela ngokuguquguquka kokukhetha,
Iivalve ezikumgangatho ophezulu zibonelela ngenkonzo ekhuselekileyo phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, kunye
Zinolawulo olungaphantsi kunezinye iivalvu.
Eyona nto ingalunganga kwezi zivalo zezi zilandelayo:

Jikelezisa indawo yesibambo sevalvu,
ayinakusetyenziselwa ukuxinga, kunye
Ezi zivalo zineendlela zokuvula kufuneka zifakwe zime nkqo.
KwiiNjineli zePntek, sinoluhlu olubanzi lweevalvu ezenziwe kwiimfuno ezikhethekileyo zabathengi, kubandakanywa iivalve zebhola ezenzelwe iteknoloji yakutshanje kwaye ifanelekile kwimisebenzi ebalulekileyo. Iivalvu zethu kulula ukuzisebenzisa, kulula ukuzigcina, ukugcinwa okuphantsi, umgangatho ophezulu kunye nokumelana nomhlwa.
