Muva nje, iqembu lama-damper omoya afakwe umoya aqediwe ukuhlanganiswa nokuhlolwa ukuze alethwe. Atholakala ngobukhulu be-DN150, DN200, DN300, DN400 kanye ne-DN600, la ma-damper ahlinzekwa ngezinsimbi ze-carbon kanye nezinsimbi ezingagqwali kubathengi bomhlaba wonke ababandakanyeka ekuphefumuleni kwezimboni, ekwelashweni kwegesi elahliwe, emapayipini okuhambisa ukushisa kanye namaphrojekthi okususa uthuli lwensimbi.

Eyaziwa nangokuthi ama-ventilation butterfly dampers, lolu chungechunge lusebenzisa isakhiwo esihlanganisiwe esifakwe ama-actuator omoya ukusekela ukuvala okude kanye nokulawulwa kokugeleza. Umzimba we-valve unokuqina okuphezulu kanye nokuvalwa kwe-shaft okwenziwe ngcono ukunciphisa ukuvuza. Ama-air dampers ensimbi engagqwali anikeza ukumelana okuhle kakhulu kokugqwala kanye nokushisa okuphezulu kwezimo zegesi yomswakama emanzi neyonakalisayo, kuyilapho izinhlobo ze-carbon steel zinikeza ukusebenza okungabizi kakhulu kwamapayipi ajwayelekile okuhambisa umoya oshisayo nomoya.

Izinzuzo ezibalulekile zifaka phakathi ukumbozwa kosayizi ogcwele kwezinhlelo zamapayipi amancane kuya kwamakhulu. Ukusebenza komoya kuqinisekisa impendulo esheshayo. Ama-valve e-solenoid ahambisanayo kanye nezinkinobho zomkhawulo zivumela ukuhlanganiswa okulula nezinhlelo zokulawula okuzenzakalelayo. Ukuxhumeka okugoqekile kwenza kube lula ukufakwa nokugcinwa endaweni. Ukumelana nokugeleza okuphansi kuqinisekisa ukusebenza kahle komoya okuphezulu kokubili kokuvala kanye nokulungiswa komthamo womoya okuqhubekayo.

Izinto ezifanelekile zifaka umoya ozungezile, umoya oshisayo, igesi yomoya ongcolile kanye negesi egcwele uthuli. Isetshenziswa kabanzi ekususweni kothuli olusebenzisa insimbi, ekuhlanzweni kwegesi yemfucuza yezimboni, emigudwini ye-HVAC, emapayipini asekela ukushiswa kwemfucuza, ukujikeleziswa komoya oshisayo wesitshalo sikasimende kanye nezinhlelo zokungenisa umoya zokwelashwa kwamanzi. Osayizi abakhelwe ngokwezifiso, izembozo zokulwa nokugqwala kanye nokuthuthukiswa kwezinga lokushisa eliphezulu kuyatholakala ukuze kuhlangatshezwane nezindinganiso zephrojekthi zomhlaba wonke.

I-valve ngayinye ye-damper idlula ekuhlolweni okuqinile kokusebenza kwayo ngaphambi kokuthunyelwa. Sisebenzela osonkontileka be-EPC bomhlaba wonke, abakhiqizi bemishini kanye nabalingani bokuhweba, sinikeza amaphepha edatha aphelele, imidwebo kanye nezixazululo ezenziwe ngokwezifiso.
