Ivalve yeglowubhu

Iivalve zeGlobe, kubandakanywa ivalve yeglowubhu ye-engile,ivalve yeglowubhu yentsimbi eyenziweyo, kunye neevalvu zeglowubhu ezibunjiweyo, zibonelela ngeengenelo ezahlukileyo kwiinkqubo ezahlukeneyo zemizi-mveliso.

Enye inzuzo ephambili yeevalvu zesango lulawulo lwazo oluhle kakhulu lokuhamba. Iivalvu zesango zibonelela ngendlela yokuhamba ethe tye xa ivuleke ngokupheleleyo, ivumela uthintelo lokuhamba oluncinci. Olu phawu luluncedo ngakumbi kwizicelo ezifuna ukuhamba ngokungenamiqathango, njengeenkqubo zokusasazwa kwamanzi, imibhobho yepetroleum, kunye nothutho lwegesi yendalo.

Enye inzuzo yeevalve zesango kukukwazi ukutywinwa okuthembekileyo. Isango kwivalve yesango lisebenza njengesivalo ukuvala ngokupheleleyo okanye ukuvumela ukuhamba xa livuliwe okanye livaliwe ngokupheleleyo. Olu luyilo luqinisekisa ukutywinwa okuqinileyo, ukuthintela nayiphi na ukuvuza kunye nokunciphisa umngcipheko wokulahleka kwemveliso okanye ukungcoliswa kwendalo. Ukutywinwa okuthembekileyo kokutywinwa kweevalvu zesango kubenza bafaneleke kwizicelo ezibalulekileyo apho ukusebenza okungavuziyo kubalulekile.

Isishwankathelo, iivalvu zesango, kubandakanywa iivalvu zeglowubhu ze-engile, iivalve zeglowubhu zentsimbi ezibunjiweyo, kunyeivalve yeglowubhu eyenziweyo, zibonelela ngezinto eziluncedo ezifana nolawulo olubalaseleyo lokuhamba, amandla okutywina athembekileyo, ukuqina, kunye nokuhla koxinzelelo oluncinci. Ezi mpawu zenza i-valve yesango ibe yinto ethembekileyo yokukhetha uluhlu olubanzi lwezicelo zoshishino, ukuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle.
