Ivalvu yekuhlola lejikeletako yesivalo serabhaluhlobo lwe-check valve lesetjentiswa kakhulu etimbonini letehlukahlukene kulawula kuhamba kwemanti. Ifakwe situlo serabha lesiniketa sivalo lesicinile futsi sivimbela kugeleta emuva. Le valve yentelwe kuvumela lutfuli kutsi lugelete ngakulolunye luhlangotsi ngesikhatsi luvimbela kutsi lugelete ngalenye indlela.

Lomunye timphawu letiyinhloko irabha ahleti swing uhlole valves kulula kwabo. Ihlanganisa i-disc lene-hinged lejikeletako ivuleke futsi ivalwe kwentela kuvumela noma kuvikela kugeleta kwemanti. Sihlalo serabha sicinisekisa kuvala lokuphephile uma ivalve ivaliwe, kuvikela kuvuza. Loku kuba lula kwenta kufakwa kanye nekunakekelwa kube lula, kwenta kutsi kube yintfo lethandwako etincenyeni letinyenti.

Lokunye lokubalulekile kwemavalvu ekuhlola lajikeleta ngesihlalo senjoloba likhono lawo lekusebenta kahle ngisho nasekugelezeni lokuphansi. Kunyakata kwe disc lokunyakatako kuvumela kugeleta lokubushelelezi, lokute tihibe, kunciphisa kwehla kwemfutfo kanye nekunciphisa kuphitsitela. Loku kwenta kutsi kube kuhle kakhulu ekusebentiseni lokudzinga emazinga laphansi ekugeleta, njengekufaka emapayipi emakhaya noma tinhlelo tekunisela.

Ngetulu kwaloko, situlo se-valve se-rabha siniketa timphawu letinhle kakhulu tekuvala. Ingamelana nekushisa lokuhlukahlukene kanye nekucindzeteleka, kucinisekisa kuvala lokutsembekile, lokucinile ngisho nangaphansi kwetimo tekusebenta letilukhuni. Loku kwenta kutsi emavalvu ekuhlola lajikeleta ngesitulo se-rubber alungele kusetjentiswa etimbonini letehlukahlukene, letifaka ekhatsi kucubungula emakhemikhali, kuhlanta emanti, kanye nawoyela negesi.

I-swing check valve levaliwe ngerabha iyintfo legucugucukako naletsembekile lesetjentiselwa kulawula kuhamba kwemanti etimbonini letehlukahlukene. Kulula kwayo, kusebenta kahle ngesilinganiso lesiphansi sekugeleta, timphawu letinhle kakhulu tekuvala kanye nekumelana nekugcola kwenta kutsi kube yintfo letsandvwako yekusebentisa lokuningi. Noma ngabe isetjentiswa etikhungweni tekuhlanta emanti, tinhlelo temaphayiphi etimbonini noma tindzawo tekucubungula emakhemikhali, le valve icinisekisa kuhamba lokubushelelezi, lokulawulwako kwetintfo letimanti ngesikhatsi ivikela noma ngukuphi kubuyela emuva.
