Ukukhethwa kwezinto: i-API American standard cast steel check valve ukukhethwa kwezinto kuhlangabezana namazinga afanelekayo ekhaya naphesheya, ikhwalithi ephelele yezinto iphakeme, ukuqinisekisa ukuqina nokwethembeka kwe-valve.
Ukusebenza okuphezulu kokuvala: umbhangqwana wokuvala uphambili futhi unengqondo, indawo yokuvala yediski ye-valve nesihlalo yenziwe nge-alloy esekelwe ku-iron noma i-Stellite cobalt-based cemented carbide surfacing, enokumelana kahle nokuguga, ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, ukumelana nokuklwebheka kanye nokuphila isikhathi eside.
Izindinganiso ezahlukene zokuxhuma i-flange: izindinganiso ezahlukene ze-flange yepayipi kanye nezinhlobo zokuvala i-flange zingasetshenziswa ukuhlangabezana nezidingo ezahlukene zobunjiniyela kanye nezidingo zomsebenzisi.
Uhlanganisela izinhlobonhlobo zezinto zomzimba: ama-gasket angakhethwa ngokufanele ngokwemibandela yokusebenza yangempela noma izidingo zomsebenzisi, futhi angasetshenziswa ezimeni ezahlukahlukene zengcindezi, izinga lokushisa kanye nemidiya.
Ukulungiselelwa okuqinile: amavalvu okuhlola anezimo ezahlukene zokwakheka kanye nezimo zokuxhuma zingaklanywa futhi zenziwe ngokuya ngezidingo zomsebenzisi ukuze kusekelwe imishini ehlukahlukene.
Ukuze kuqinisekiswe ukusebenza okuvamile futhi kunwetshwe impilo yesevisi yamavalvu okuhlola insimbi eyenziwe nge-API, kufanele kwenziwe ukugcinwa okuvamile nokulungiswa. Kubandakanya ukuhlola ukusebenza kokuvala kwevalvu, ukuhlanza ukungcola nokungcola ngaphakathi kwevalvu, ukufaka izimpawu ezidliwe nokunye. Ngasikhathi sinye, kufanele futhi unake imiyalelo yokusebenza nokugcinwa kwevalvu ukugwema ukulimala noma ukwehluleka kwevalvu okubangelwa ukusebenza kabi noma ukugcinwa okungalungile.
