Iindaba zeShishini

Iivalvu zokujonga ziimveliso zolawulo lwamanzi eziyimfuneko kushishino lwangoku kwaye ngoku zezinye zezona ntlobo zisetyenziswa kakhulu zeevalvu.

Kukho iintlobo ezine zeevalvu zokutshekisha: ukuphakamisa kunye nokulahla, ukujinga, ibhola kunye nepleyiti

Ulwalathiso lokufakela iivalve zebhabhathane kufuneka lumiselwe ngokohlobo lwazo kunye neemeko zokusebenza.

Ubomi benkonzo yeevalve zebhabhathane buchatshazelwa zizinto ezininzi ezidibeneyo, zihlala ziguquguquka phakathi kweminyaka emi-5 ukuya kwengama-20.

Iivalvu zebhabhathane, ngenxa yolwakhiwo lwazo olwahlukeneyo kunye neefom zokutywina eziguquguqukayo, ziyakwazi ukuziqhelanisa neemeko ezahlukeneyo zemidiya kwaye zinokwahlulwa ngokuthe ngqo kwezi ndidi zilandelayo.

Kwiindawo eziphantsi kobushushu, ukusebenza kweevalvu zebhola kuya kuchaphazeleka kakhulu
