Ukuba unolwazi olusisiseko lwevalvu, mhlawumbi uqhelene naloivalve yebhola- enye yeentlobo eziqhelekileyo zeevalvu ezikhoyo namhlanje.Ivalve yebhola ngokuqhelekileyo yivalve yekota enebhola enemingxuma embindini ukulawula ukuhamba.Ezi zivalo zaziwa ngokomelela ngokuvalwa okugqwesileyo, kodwa azisoloko zibonelela ngolawulo oluchanekileyo.Masithethe xa kulungile ukusebenzisa ivalve yebhola njengevalve yokulawula.
Nangona iivalvu zebhola zingesona sixhobo silungileyo sokulawula ukuhamba, zisasetyenziswa ngokuxhaphakileyo ngenxa yexabiso lazo elisebenzayo.Unokuhamba usebenzisa ivalve yebhola kwisicelo esingadingi uhlengahlengiso oluchanekileyo kunye nolawulo.Ngokomzekelo, i-valve yebhola kufuneka ingabi nangxaki yokugcina itanki enkulu ezaliswe kwinqanaba elithile ngaphakathi kwee-intshi ezimbalwa.
Njengaso nasiphi na isixhobo, kuya kufuneka uthathele ingqalelo iimeko zenkqubo epheleleyo ngaphambi kokuba ukhethe ivalve yakho.Oku kuquka imveliso okanye imathiriyeli, ubungakanani bombhobho, umlinganiselo wokuqukuqela, njl.njl. Ukuba uzama ukulawula imathiriyeli ebiza kakhulu onexhala lokumosha, usenokungafuni ukuxhomekeka kwivalve yebhola.
Iivalvu zebhola azichanekanga kakhulu kuba uhlengahlengiso lwazo alulingani nomthamo omkhulu wokuqukuqela obonelelwa ngumngxuma ovulekileyo.Kukwakho 'ukutyibilika' okanye 'ukudlala' phakathi kwesiqu kunye nebhola okuthintela ulawulo oluchanekileyo.Okokugqibela, ubungakanani betorque efunekayo ukulungisa iivalvu zebhola ayikuvumeli uhlengahlengiso olucolekileyo kufutshane nendawo “evaliweyo” kunye “neyokuvula”.
