Kummandla weenkqubo zokulawula ulwelo, iivalvu zidlala indima ebalulekileyo ekulawuleni uxinzelelo, ukuqukuqela, nendlela. Phakathi kweentlobo ezahlukeneyo zeevalvu, iivalve ezisebenzayo (i-POVs) kunye neevalvu zoncedo (RVs) zigqama njengezinto ezibalulekileyo zokuqinisekisa ukhuseleko kunye nokusebenza kakuhle. Ngelixa bobabini besebenzela injongo yokulawula uxinzelelo, bayahluka kwiindlela zabo zokusebenza kunye nezicelo.
Iivalvu eziqhutywayo zolingelo, ezikwaziwa ngokuba ziivalve ezilungelelanisiweyo, zisebenzisa ivalufa encedisayo ukulawula ivalve enkulu. Olu luyilo olunamanqanaba amabini lubonelela ngeenzuzo ezininzi:
UkuLawulwa koxinzelelo oluchanekileyo: Ii-POVs zibonelela ngolawulo loxinzelelo oluchanekileyo, zizenza zilungele izicelo apho ukulawulwa koxinzelelo oluchanekileyo kubaluleke kakhulu.
UkuNciphiswa kokuNxitywa kunye nokukrazuka: Ivalve yokulinga ikhusela ivalve engundoqo ekuchanabekeni ngokuthe ngqo kuxinzelelo lwenkqubo, ukunciphisa ukuguga nokukrazuka kunye nokwandisa ubomi bevalvu.
Ukutywinwa okuPhakamileyo: Ii-POVs zigcina isitywina esiqinileyo nanjengoko uxinzelelo lwenkqubo lusondela kuxinzelelo olubekiweyo, luthintela ukuvuza kunye nokuqinisekisa ukuthembeka kwenkqubo.
I-Versatility in Applications: Ii-POVs zisebenza ngeendlela ezininzi kwaye ziyakwazi ukujongana noluhlu olubanzi loxinzelelo, ulwelo, kunye neemeko zokusebenza.
Iivalvu zoncedo, ezikwabizwa ngokuba ziivalvu zokhuseleko, zisebenza njengenetha yokhuseleko lweenkqubo zolwelo, ukuthintela uxinezeleko olugqithisileyo kunye neengozi ezinokwenzeka. Basebenza ngokuvula ngokuzenzekelayo xa uxinzelelo lwenkqubo ludlula indawo ebekiweyo, ikhupha uxinzelelo olugqithisileyo ukukhusela inkqubo.
Uncedo loxinzelelo olukhawulezileyo: Ii-RVs zibonelela ngokukhawuleza koxinzelelo, zikhusela ngokufanelekileyo iinkqubo zoxinzelelo olukhawulezileyo.
Ubulula boYilo: Ii-RV zilula kuyilo, nto leyo eyenza kube lula ukuzifaka, ukuzigcina, kunye nokusombulula ingxaki.
Isisombululo esiSebenza ngeendleko: Ii-RVs zidla ngokuba neendleko ezithe kratya xa zithelekiswa nee-POVs.
Ukhetho phakathi kwevalve esebenzayo yomqhubi kunye nevalve yokunceda kuxhomekeke kwisicelo esithile kunye neemfuno zokusebenza. Nasi isishwankathelo sokukhokela isigqibo sakho:
Kulawulo oluchanekileyo loxinzelelo kunye nezicelo ezifuna ukuvuza okuncinci, ii-POVs lukhetho olukhethwayo.
Ukukhusela uxinzelelo olugqithisileyo kunye nokunciphisa uxinzelelo olukhawulezayo kwizicelo ezingabizi kakhulu, ii-RVs zisisombululo esifanelekileyo.
