I-valve yokumisa, eyaziwa nangokuthi i-valve yokusika, iyivalve yokuvala ngempoqo kanye nohlobo lwevalvu enqamukile. Ngokusho kwemodi yokuxhuma, ihlukaniswe yaba izinhlobo ezintathu: uxhumano lwe-flange, uxhumano lwentambo, nokuxhumeka kwe-welding.
Lolu hlobo lwe-valve yokuvala lufaneleka kakhulu ukuvala noma ukuqondisa nokudonsa. Ngenxa yokuthi i-stroke yokuvula noma yokuvala ye-valve stem yalolu hlobo lwe-valve ifushane, futhi inomsebenzi wokuvala onokwethenjelwa kakhulu, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve ngokulingana okuqondile nokushaywa kwe-valve disc, kufanelekile kakhulu ukulungiswa kokugeleza.
I-valve yokuvala iklanyelwe ukungena okuphansi nokuphuma okuphezulu, inhloso ukwenza ukumelana nokugeleza kuncane futhi ulondoloze umzamo lapho uvula i-valve. Ngesikhathi esifanayo, lapho i-valve ivaliwe, i-gasket phakathi kwe-valve casing kanye nesembozo se-valve kanye nokupakisha okuzungeze isiqu se-valve ngeke kugcizelelwe, futhi ngeke kube ngaphansi kwengcindezi nokushisa kwe-medium isikhathi eside, okungase kunwebe impilo yesevisi futhi kunciphise amathuba okuvuza. Ngaphezu kwalokho, ukupakisha kungashintshwa noma kwengezwe lapho i-valve ivaliwe, ekulungele ukulungiswa.
Abantu abaningi bacabanga ukuthi i-valve yokuvala iphansi futhi iphezulu, kodwa akunjalo. Ngokuvamile, i-valve yokuvala iphansi futhi iphuma phezulu, kodwa kunezimo ezikhethekile lapho i-valve yokuvala iphezulu futhi iphuma kancane:
1. I-valve yokumisa ingcindezi ephezulu enobubanzi obukhulu kuno-100mm.
2. Amavalvu okuvala amabili ochungechungeni epayipini lokudlula, i-valve yesibili yokuvala idinga "i-high inlet ne-low outlet"
3. I-boiler exhaust kanye ne-valve yokumisa umoya
4. I-valve ye-Electromagnetic ephuka ngokushesha
