Ukunqoba ukumelana kwentwasahlobo kwenza ivalvu ivuleke noma ivaleke. Uma ingcindezi ephakathi nendawo ekugcineni kokungena iphansi kunengxenye yokungena, ivalvu yokuhlola eqondile: ngenxa yengcindezi yendawo ekugcineni kokungena kwepayipi. Intwasahlobo isunduza umongo wevalvu esihlalweni sevalvu ukuze ivale ivalvu, ivimbele indawo ukuthi igeleze emuva, ngakho-ke inomsebenzi wokungabuyi. Amavalvu okuhlola aqondile asetshenziswa kabanzi embonini yamakhemikhali, igesi kaphethiloli encibilikisiwe, uketshezi kanye neminye imboni. Ngokwesakhiwo sevalvu yokuhlola, ingahlukaniswa ngezinhlobo ezintathu: ivalvu yokuhlola yokuphakamisa, ivalvu yokuhlola yokuphakamisa kanye nevalvu yokuhlola ibhabhathane.
Ivalvu esetshenziselwa ukuvimbela i-medium ukuthi igeleze emuva ibizwa nangokuthi i-check valve, i-one-way valve, i-reverse flow valve, kanye ne-back pressure valve. Ivalvu yokuhlola uhlobo lwe-valve ezenzakalelayo, umsebenzi wayo oyinhloko ukuvimbela ukugeleza kwangemuva kwe-medium, ukuvimbela ipompo kanye ne-drive motor ukuthi ibuyele emuva, kanye nokukhishwa kwe-container medium. Amavalvu okuhlola angasetshenziswa futhi ukuhlinzeka ngamapayipi lapho ingcindezi ingakhuphukela ohlelweni olusizayo oludlula ingcindezi yesistimu. Amavalvu okuhlola angahlukaniswa ngamavalvu okuhlola okujikayo (ajikeleza ngokuya ngesikhungo samandla adonsela phansi) kanye namavalvu okuhlola okuphakamisa (ahamba nge-axis). Umsebenzi walolu hlobo lwevalvu ukuvumela kuphela i-medium ukuthi igeleze ohlangothini olulodwa futhi ivimbele ukugeleza kokuqondisa. Ngokuvamile lolu hlobo lwevalvu lusebenza ngokuzenzakalelayo ngaphansi kwesenzo sengcindezi yoketshezi egeleza ohlangothini olulodwa, i-valve flap iyavuleka; lapho uketshezi lugeleza ohlangothini oluphambene, ingcindezi yoketshezi kanye nokuzivumelanisa kwe-valve flap kusebenza esihlalweni sevalvu, ngaleyo ndlela kunqamule ukugeleza. Phakathi kwazo, i-valve yokuhlola intambo yangaphakathi kanye ne-valve yokuhlola eqondile kubhekisela ekuvulekeni nasekuvalekeni okuzenzakalelayo kwe-valve clack kuye ngokugeleza kwe-medium uqobo. Ama-valve okuhlola axhunyiwe angowalolu hlobo lwe-valve, kufaka phakathi ama-valve okuhlola i-swing kanye nama-valve okuhlola i-lift. I-valve yokuhlola i-swing ine-mechanism ye-intermediary chain kanye ne-valve disc efana nomnyango ohlala ngokukhululeka ebusweni besihlalo se-valve esithambekele. Ukuze kuqinisekiswe ukuthi i-valve clack ingafinyelela endaweni efanele ebusweni besihlalo se-valve njalo, i-valve clack yakhelwe ngendlela yeketanga ukuze i-valve clack ibe nesikhala esanele sokujika futhi yenze i-valve clack ixhumane ngempela futhi ngokugcwele nesihlalo se-valve. I-valve clack ingenziwa ngensimbi, isikhumba, irabha, noma isembozo sokwenziwa singafakwa ensimbini, kuye ngezidingo zokusebenza. Lapho i-valve yokuhlola i-swing ivuliwe ngokugcwele, ingcindezi yoketshezi cishe ayivimbeki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu. I-valve disc ye-valve yokuhlola i-lift ihlezi ebusweni bokuvala besihlalo se-valve emzimbeni we-valve. Ngaphandle kokuthi idiski ingaphakanyiswa futhi yehliswe ngokukhululeka, ingxenye esele yale valve ifana nevalvu yokuvala. Umfutho woketshezi uphakamisa idiski kusuka ebusweni bokuvala besihlalo sevalvu, futhi ukugeleza komoya emuva kwe-medium kubangela ukuthi idiski iwele esihlalweni futhi inqamule ukugeleza. Ngokwemibandela yokusebenzisa, idiski yevalvu ingaba yisakhiwo sensimbi yonke, noma ingaba ngesimo sephedi yerabha noma indandatho yerabha efakwe kufreyimu yediski. Njengevalvu yokuma, ukudlula koketshezi ngevalvu yokuhlola ukuphakamisa nakho kuncane, ngakho-ke ukwehla komfutho ngevalvu yokuhlola ukuphakamisa kukhulu kunokwevalvu yokuhlola ukujikeleza, futhi ukugeleza kwevalvu yokuhlola ukuphakamisa akukhawulelwe kakhulu.

INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
