I-valve yokuhlola iyi-valve enezingxenye zokuvula nokuvala ezingama-disc, ngenxa yobukhulu bazo kanye nengcindezi yokusebenza evimbela i-medium ukuthi ibuye. Iyi-valve ezenzakalelayo, ebizwa nangokuthi i-valve yokuzihlukanisa, i-valve yokubuyisa, i-valve yendlela eyodwa, noma i-valve yokuhlola. Uhlobo lokuphakamisa kanye nohlobo lokushintsha yizigaba ezimbili lapho i-disc ingahamba khona.

Isiqu se-valve esinika amandla i-disc ku-valve yomhlaba kanye ne-liftivalvu yokuhlolababelana ngomklamo ofanayo wesakhiwo. I-medium ingena ngokufakwayo ohlangothini olungezansi bese iphuma ngomsele ohlangothini oluphezulu (ohlangothini olungaphezulu). I-valve iyavuleka lapho ingcindezi yokungena idlula isisindo sediski kanye nokumelana kwayo nokugeleza. I-valve iyavalwa lapho i-medium igeleza ngakolunye uhlangothi.

Ukusebenza kwevalvu yokuhlola ukuphakama kufana nokwevalvu yokuhlola ukujiya ngoba kokubili kufaka phakathi amapuleti okujiya ajikelezayo. Ukuze kuvinjwe amanzi ukuthi angagelezi emuva, amavalvu okuhlola avame ukusetshenziswa njengamavalvu angaphansi emishinini yokupompa. Umsebenzi wokuhlukanisa ukuphepha ungenziwa ngenhlanganisela yevalvu yokuhlola kanye nevalvu yomhlaba. Ukumelana ngokweqile kanye nokuvalwa okunganele uma kuvaliwe kuyiphutha.

Emigqeni ekhonza izinhlelo ezisizayo lapho ingcindezi ingakhuphuka ngaphezu kwengcindezi yesistimu,ama-valve okuhlolaKusetshenziswa futhi. Ama-valve okuhlola okujikijelayo nama-valve okuhlola okuphakamisa yizinhlobo ezimbili eziyinhloko zama-valve okuhlola. Ama-valve okuhlola okujikijelayo ajikeleza nendawo ephakathi yamandla adonsela phansi (ahamba eceleni kwe-axis).

Umsebenzi wale valve ukuvimbela ukugeleza kwe-medium kuya kolunye uhlangothi ngenkathi uvimba ukugeleza kolunye uhlangothi. Le valve ivame ukusebenza ngokuzenzakalelayo. Idiski yevalvu iyavuleka lapho ingcindezi yoketshezi ihamba kolunye uhlangothi; lapho ingcindezi yoketshezi igeleza kolunye uhlangothi, isihlalo sevalvu siyathinteka yingcindezi yoketshezi kanye nesisindo sediski yevalvu, evimba ukugeleza.

Lesi sigaba sama-valve sihlanganisa ama-check valve, njenge-swing check valve kanye ne-liftama-valve okuhlolaIdiski emise okwesicabha yevalvu yokuhlola ijika incike ngokukhululekile ebusweni besihlalo esigobile ngenxa yendlela yokubopha i-hinge. I-valve clack yakhiwe ngendlela yokubopha i-hinge ukuze ibe nendawo eyanele yokujika futhi ikwazi ukuxhumana ngokuphelele nesihlalo sokubopha i-valve ukuze kuqinisekiswe ukuthi ingahlala ifinyelela endaweni efanele ebusweni besihlalo.

Kuye ngokusebenza okudingekayo, amadiski angakhiwa ngokuphelele ngensimbi noma abe nezembozo zesikhumba, zerabha, noma zokwenziwa ensimbini. Umfutho woketshezi awuphazanyiswa nhlobo uma ivalvu yokuhlola ukujika ivuliwe ngokugcwele, ngakho-ke ukulahlekelwa kwengcindezi ngevalvu kuncane kakhulu.

Indawo yokuvala yesihlalo sevalvu emzimbeni wevalvu yilapho idiski yevalvu yokuhlola ukuphakama itholakala khona. Ingxenye esele yevalvu ifana nevalvu yomhlaba, ngaphandle kokuthi idiski ingaphakama futhi iwe ngokukhululeka. Uma kukhona ukugeleza emuva kwe-medium, idiski yevalvu ibuyela esihlalweni sevalvu, inqamule ukugeleza. Umfutho woketshezi uphakamisa idiski yevalvu endaweni yokuvala yesihlalo sevalvu. Idiski ingenziwa ngensimbi ngokuphelele, noma ingaba nezindandatho zerabha noma amaphedi afakwe kufreyimu yediski, kuye ngezimo zokusetshenziswa.

I-valve yokuhlola ukuphakama inendlela encane yokungena koketshezi kune-valve yokuhlola ukujiya, okuholela ekwehleni okukhulu kwengcindezi nge-valve yokuhlola ukuphakama kanye nesilinganiso sokugeleza kwe-valve yokuhlola ukujiya esiphansi.
