Incazelo eningiliziwe ye-Check Valve:
Bheka ama-valves ama-valves avumelwayo, owaziwa nangokuthi ama-valves e-Check, ama-valves wendlela eyodwa, ama-valves abuyayo noma ama-solate valve. Ukuhamba kwe-disc kuhlukaniswe ngohlobo lwe-lift kanye nohlobo lokujikisa. I-Volve ye-Lift Checkve iyafana ngesakhiwo kwi-valve evaliwe, kepha ayinaso isiga se-valve esidonsa i-disc. Ukugeleza okuphakathi kusuka ekupheleni kwendawo (ohlangothini oluphansi) futhi kuvela endaweni yokuphuma (uhlangothi olungaphezulu). Lapho ingcindezi ye-inlet inkulu kunesamba sesisindo se-disc kanye nokuphikiswa kwayo, i-valve ivuliwe. Ngokuphambene nalokho, i-valve ivaliwe lapho i-lipering igeleza ibuyela emuva. I-Swing Check valve ine-disc ethambekele futhi ingajikeleza eduze kwe-eksisi, futhi umgomo osebenzayo ufana ne-lift Check Valve. I-valve yesheke ivame ukusetshenziswa njenge-valve engezansi yedivaysi yokupompa ukuvikela ukubuyela kwamanzi emuva. Inhlanganisela ye-Check valve nokumisa i-valve ingadlala indima yokuhlukaniswa kokuphepha. Okubi ukuthi ukumelana kukhulu futhi ukusebenza kokubekwa uphawu kumpofu lapho kuvaliwe.
