Mabapi le DRV Swing Check Valve:
Li-valve tsa ho hlahloba li-swing li tla le litulo tse tsitsitseng.E kentsoeng lits'ebetsong tsa ho pompa ho thibela ho phalla ha morao li ka sebelisoa bakeng sa metsi a nooang hammoho le metsi a litšila.Diski e hokahane le shaft ka sehlahla se tenyetsehang se lumellang disc le setulo sa valve ho ikamahanya hantle.Likarolo tsohle tse ka hare ke tšepe ea ductile e koahetsoeng ka metsi a nooang a lumelletsoeng epoxy kapa EPDM.
Ductile Iron Check Valve ea boleng bo holimo, e leng tharollo e ncha ea lipeipi e etselitsoeng ho fihlela litlhoko tsa sistimi ea sejoale-joale ea lipeipi.Sephahla sena se etselitsoe ho sebetsa ka katleho tlas'a maemo a khatello e phahameng le ho netefatsa ts'ebetso e ka tšeptjoang ka tlhokomelo e fokolang.
E entsoe ka thepa ea tšepe ea boleng bo holimo ea ductile, valve ena e etselitsoe ho fana ka matla a phahameng, ho tšoarella le ho hanyetsa kutu.E khona ho mamella maemo a thata a leholimo le maemo a leholimo a feteletseng, e leng se etsang hore e be khetho e nepahetseng bakeng sa lits'ebetso tsa kantle.
