Ivalve yokukhupha ivelufa esetyenziselwa ukukhupha irhasi eqokelelweyo okanye umoya kwimibhobho.Ikakhulu ibandakanya umzimba wevalvu, isivalo sevalvu, kunye nesakhiwo sangaphakathi sevalvu, enemisebenzi efana nokuthintela ukugqabhuka kwemibhobho kunye nokukhupha iigesi.Ivalve yokukhupha ingahlulwa ibe ziindidi ezimbini: manual and automatic.I-valve yokukhupha i-valve ye-manual idinga ukusebenza ngesandla ukulawula ukuhamba kwegesi, ngelixa i-valve yokukhupha ngokuzenzekelayo ikwazi ukubona ngokuzenzekelayo umoya kunye namanzi kumbhobho, ukufezekisa injongo yokukhupha okuzimeleyo.Ngokuphathelele kwimihlaba yesicelo, iivalve zokukhupha zisetyenziswa ngokubanzi kwimibhobho yokwakha, ukunikezelwa kwamanzi kunye nokukhupha amanzi, ubunjineli bakamasipala, izityalo zamachiza, izityalo zamachiza, imboni yokutya, kunye nezinye iindawo.Ekwakhiweni kwemibhobho, iivalve zokukhupha zingakhupha igesi kumbhobho kwaye zithintele ukugqabhuka kwemibhobho;Kwinkqubo yokubonelela ngamanzi kunye nenkqubo yokukhupha amanzi, i-valve yokukhupha inokuphelisa uxinzelelo olubi lwegesi kwipayipi kwaye igweme ukuxhathisa umoya;Kwimimandla efana nezityalo zekhemikhali, izityalo zamachiza, kunye neshishini lokutya, iivalve zokukhupha zinokuthintela ukuqokelelwa kweegesi kwaye ziphephe iimpembelelo ezimbi kwindawo yokuvelisa.Ngamafutshane, iivalve zokukhupha, njengevalve ebalulekileyo yombhobho, zisetyenziswa ngokubanzi kwimimandla efana nemibhobho yokwakha, ukunikezelwa kwamanzi kunye nokukhupha, kunye nezityalo zekhemikhali.Okwangoku, ngokuphuculwa okuqhubekayo koshishino kunye nophuhliso lwemimandla ekhulayo, amathuba okusetyenziswa kweevalvu zokukhupha nawo aya kuba banzi.Le mveliso inesatifikethi seCE.
