Ukutywinwa kweevalvu zebhola ikakhulu kuxhomekeke ekubambeni okuqinileyo phakathi kwebhola kunye nesitulo sevalve.

Isizathu sokuba kutheni iivalvu zebhola zinokuvuleka nokuvala ngokukhawuleza kungenxa yendlela eyodwa yokuvula nokuvala kunye noyilo lolwakhiwo.

Ukulungiswa kweengxaki zee-valve zokutshekisha kufuneka zidibaniswe kunye neentlobo eziqhelekileyo zeempazamo kwaye zihlalutywe ngokuchanekileyo inyathelo ngesinyathelo.

Njengesixhobo esiphambili sokuthintela umva ophakathi, iivalve zokujonga zisetyenziswa ngokubanzi kwiinkqubo zemibhobho.

Jonga ivalve, ebizwa ngokuba yiValve yeHowve okanye ivalve enye, yinto ebalulekileyo kwiinkqubo zokulawula. Eyona njongo iphambili kukuthintela ukubuyela umva kwe-hidflow, qinisekisa ukuhamba ngendlela enye yokuhamba, ukukhusela izixhobo, kunye nokugcina ukusebenza kwezinzile.

Ukukhethwa kwamasango eendawo zesango ngamaqondo obushushu aphantsi kufuneka kuthathwe ngqo kwimiba emithathu: ukuqina kwezinto, ukusebenza, kunye noyilo lwesakhiwo
