Intonga yokudibanisa engenantlokoivalvu yokuthintela umoya, njengecandelo lolawulo oluphambili kwiinkqubo zokungenisa umoya kwimizi-mveliso kunye neenkqubo zokuhambisa umoya, ineenzuzo ezininzi ezibalulekileyo. Eyona nto iphambili kuyo kukushiya isakhiwo sentloko yevalvu esizimeleyo seevalvu zedamper zemveli. Ngokusebenzisa uyilo oludibeneyo lokuhambisa intonga yokudibanisa, isakhiwo siphela senziwe lula kakhulu, okwenza ivolumu ibe ncinci ngakumbi. Ingaqhelana neemeko zokusebenza kunye noyilo lwezixhobo ezixineneyo kwaye yonge indawo yokufaka.

Ii-dampers zifumaneka kakhulu kwiinkqubo zokungenisa umoya ezikwifektri, kwiinkqubo zomoya omtsha kwiindlela ezingaphantsi komhlaba, nakwiipayipi zegesi zombhobho zeebhoyila. Iivalvu zeButterfly zisetyenziswa kakhulu kwimibhobho yokuhambisa amanzi kwimisebenzi yamanzi, kwiinkqubo zamanzi omoya opholileyo, kunye neekhonkco zokusika ulwelo kwizityalo zepetrochemical.

Umahluko obalulekileyo phakathi kwee-air dampers kunye nee-butterfly valves usekwe kwindlela ezisetyenziswa ngayo kunye noyilo oluphambili lokusebenza. I-flue gas damper igxile ekulawuleni umthamo womoya, ikhokela kwaye inqumle ukuhamba kweegesi (ingakumbi umoya, i-flue gas kunye nothuli), ngelixa ii-butterfly valves zisebenza kakhulu ukucima nokulawula ukuhamba kolwelo, iigesi okanye umphunga. Ngenxa yeempawu ezahlukeneyo eziphakathi kunye neemeko zokusetyenziswa, umahluko ophambili wenziwa kwisakhiwo, ukugxila kokutywina kunye neempawu zokusebenza.

Ngokwembono yesakhiwo, ii-damper ze-Guillotine zihlala zisebenzisa ii-valve cores ze-multi-blade, i-plug plate okanye i-baffle type. Ezinye, ezifana ne-connecting rod headless air damper, zikwaphucula indlela yokuhamba kwegesi ngokudluliselwa kwe-connecting rod. Uyilo lokutywina lugxile ekunciphiseni "izinga lokuvuza komoya" ukuze kuhlangatyezwane neemfuno zokuzinza kokuhamba komoya ekuphefumleni umoya, ekususweni kothuli, kwi-HVAC nakwezinye iinkqubo. Ii-Butterfly valves zinomongo we-valve ojikelezayo ofana nediski njengesiseko sazo. Umongo we-valve ujikeleza i-valve shaft ukuze kuvuleke kwaye kuvalwe. Uyilo lokutywina lugxile "ekuthinteleni ukuvuza" kwaye kufuneka luhlangabezane nenqanaba elithile lokumelana noxinzelelo. Zifanelekile kwiimeko zothutho lolwelo ezifana nokubonelela ngamanzi kunye nokutsalwa kwamanzi, ishishini leekhemikhali, kunye nemibhobho yobushushu.

Ngokuphathelele izalathisi zokusebenza, iivalvu zomoya zinika ingqalelo engakumbi ekuchanekeni kokulawulwa komthamo womoya kunye nokuxhathisa ukukhukuliseka kothuli ukuze zikwazi ukumelana nokuguguleka kwezinto ezibangelwa kukuhamba komoya okunothuli. Iivalvu zebhabhathane zigxininisa ngakumbi kwisantya sokuvula nokuvala, ukumelana noxinzelelo kunye nokusebenza kokutywina, kunye nobomi benkonzo. Ezinye iivalvu zebhabhathane ezinoxinzelelo oluphezulu nazo kufuneka zibe nakho ukumelana nokuxinana kwe-cavitation.
