I-valve yokuhlola i-valve izingxenye zayo zokuvula nokuvala zingamadiski, okuthi ngenxa yobuningi bawo kanye nokucindezela kokusebenza kuvimbele okuphakathi ukuthi kungabuyi. I-valve ezenzakalelayo, ebizwa nangokuthi i-valve yokuhlukanisa, i-valve yokubuyisela, i-valve yendlela eyodwa, noma i-valve yokuhlola. Uhlobo lokuphakamisa nohlobo lokushwiba yizigaba ezimbili idiski engahamba ngaphansi kwazo.

Isiqu se-valve esinika amandla i-disc ku-valve yembulunga kanye nokuphakamisahlola i-valveukwabelana ngomklamo ofanayo wesakhiwo. I-medium ingena ngokufaka ohlangothini olungezansi bese iphuma nge-outlet eseceleni engaphezulu (uhlangothi olungaphezulu). I-valve ivula lapho ukucindezela kwe-inlet kudlula inani lesisindo sediski kanye nokumelana nokugeleza kwayo. I-valve ivaliwe lapho i-medium igeleza ngokuphambene.

Ukusebenza kwevalve yokuhlola i-lift kufana nalokho kwevalvu yokuhlola ukushwibeka ngoba kokubili kuhlanganisa amapuleti e-swash ajikelezayo. Ukuze kuvinjwe amanzi ukuthi angagelezi aye emuva, ama-valve okuhlola asetshenziswa kaningi njengamavalufu aphansi emishini yokumpompa. Umsebenzi wokuhlukanisa ukuphepha ungenziwa nge-valve yokuhlola kanye nenhlanganisela ye-globe valve. Ukumelana okweqile kanye nokuvala uphawu okunganele uma kuvaliwe kuyimbuyiselo.

Emigqeni enikeza amasistimu asizayo lapho ingcindezi ingase yenyuke ngaphezu kwengcindezi yesistimu,hlola ama-valvenazo ziyaqashwa. Ama-valve okuhlola ama-Swing kanye nama-valve okuhlola okuphakamisa yizinhlobo ezimbili eziyinhloko zama-valve okuhlola. Ama-valve okuhlola i-Swing azungeza phakathi nendawo yamandla adonsela phansi (ahamba e-eksisi).

Umsebenzi wale valve uwukukhawulela ukugeleza kwe-medium kuya ohlangothini olulodwa ngenkathi uvimba ukugeleza kolunye uhlangothi. Le valve ivamise ukusebenza ngokuzenzakalelayo. I-valve disc ivuleka lapho umfutho we-fluid uhamba ohlangothini olulodwa; lapho umfutho we-fluid ugeleza ngakolunye uhlangothi, isihlalo se-valve sithinteka ukucindezela kwamanzi kanye nesisindo se-valve disc, esivimbela ukugeleza.

Lesi sigaba sama-valve sihlanganisa ama-valve okuhlola, njengama-valve okuhlola ama-swing kanye nokuphakamisahlola ama-valve. I-disc emise okwesicabha yevalvu yokuhlola i-swing incike ngokukhululekile endaweni yesihlalo esitshekile ngenxa ye-hinge mechanism. I-valve clack yakhiwe ngendlela yehinge ukuze ibe nendawo eyanele yokushwiba futhi ikwazi ukuxhumana ngokuphelele neqiniso nesihlalo se-valve clack ukuze kuqinisekiswe ukuthi ingafika njalo endaweni efanele yendawo yokuhlala.

Kuye ngokusebenza okudingekayo, ama-disc angakhiwa ngokugcwele ngensimbi noma abe nesikhumba, irabha, noma izembozo zokwenziwa ensimbi. Ukucindezela koketshezi cishe akuvinjiwe ngokuphelele lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, ngakho-ke ukulahlekelwa kwengcindezi nge-valve kuncane.

Indawo yokuvala yesihlalo se-valve emzimbeni we-valve yilapho i-lift check valve disc ikhona. I-valve esele ifana ne-globe valve, ngaphandle kokuthi idiski ingakhuphuka futhi iwe ngokukhululeka. Uma kukhona ukubuyela emuva kwe-medium, i-disc ye-valve iwela emuva esihlalweni se-valve, inqamule ukugeleza. Umfutho we-fluid uphakamisa i-valve disc isuke endaweni yokuvala yesihlalo se-valve. Idiski ingenziwa ngensimbi ngokuphelele, noma ingaba namaringi erabha noma amaphedi afakwe kuhlaka lwediski, kuye ngezimo zokusetshenziswa.

I-valve yokuhlola i-lift ine-passage encane yoketshezi kune-valve yokuhlola i-swing, okuholela ekwehleni kwengcindezi enkulu nge-valve yokuhlola i-lift kanye nezinga eliphansi lokugeleza kwe-valve yokuhlola.
