I-valve ye-radiator iyi-valve esetshenziselwa ukulawula ukushisa kwemishini yokufudumeza.Ivamise ukufakwa kumshini wokushisa noma amapayipi okushisa, futhi ilungise ukugeleza kwamanzi ashisayo noma umusi ngokulawula ukuvulwa nokuvalwa kwama-valve, ngaleyo ndlela ilawule izinga lokushisa langaphakathi.Ngokukhethekile, lapho izinga lokushisa lasendlini lidinga ukushiselwa, i-valve yerediyetha iyavulwa, amanzi ashisayo noma isitimu sigeleze singene emshinini wokushisisa noma ipayipi lokushisisa ngevalvu, futhi ikhiphe ukushisa ekamelweni nge-radiator noma irediyetha.Lapho izinga lokushisa elingaphakathi endlini lifinyelela inani elimisiwe, i-valve ye-radiator ivaliwe ukuze kumiswe inqubo yokushisa.Kunezindlela eziningi zokulawula i-valve ye-radiator, kuhlanganise nokulawula okwenziwa ngesandla, ukulawula ukushisa okuzenzakalelayo nokunye.Ngokuvamile, i-valve ye-radiator idlala indima ekulawuleni izinga lokushisa lasendlini kanye nokonga amandla ohlelweni lokushisa, futhi ingalungiswa ngokuvumelana nezidingo zokugcina igumbi lisezingeni lokushisa elikhululekile.
