Ivalve yeradiyetha yivalve esetyenziselwa ukulawula ukufudumeza kwezixhobo zokufudumeza.Ngokuqhelekileyo ifakwe kwizixhobo zokufudumeza okanye ukufudumeza imibhobho, kwaye ilungelelanise ukuhamba kwamanzi ashushu okanye i-steam ngokulawula ukuvulwa kunye nokuvalwa kwee-valve, ngaloo ndlela ilawula ukushisa kwangaphakathi.Ngokukodwa, xa iqondo lokushisa langaphakathi lifuna ukufudumeza, i-valve ye-radiator ivuliwe, amanzi ashushu okanye i-steam igeleza kwisixhobo sokufudumeza okanye umbhobho wokufudumeza ngevalve, kwaye ikhuphe ukushisa kwigumbi nge-radiator okanye i-radiator.Xa ubushushu bangaphakathi bufikelela kwixabiso elimiselweyo, ivalve yeradiyetha ivaliwe ukumisa inkqubo yokufudumala.Kukho iindlela ezininzi zokulawula ivalve yeradiyetha, kubandakanywa nolawulo lwe-manual, ulawulo oluzenzekelayo lobushushu kunye nokunye.Ngokuqhelekileyo, ivalve yeradiyetha idlala indima ekulawuleni ubushushu bangaphakathi kunye nokugcina amandla kwinkqubo yokufudumeza, kwaye inokulungelelaniswa ngokweemfuno zokugcina igumbi kwiqondo lokushisa elikhululekile.
