Ngaphakathi kwevalve yokutshixa umoya, umoya uvaliwe (utshixiwe) phakathi kwendawo yokungena nokuphumayo.I-vanes, okanye iincakuba zentsimbi, zevalvu ejikelezayo yokuvala umoya (ijikelezisa) ngexesha lokusebenza.Njengoko besenza, iipokotho zenza phakathi kwabo.Izinto eziphathwayo zingena ezipokothweni ngezibuko lokungena ngaphambi kokujikeleza ngaphakathi kwevalve emva koko uphume ngezibuko lokuphuma.Kwivalve yokuvala umoya, umoya uvaliwe (utshixiwe) phakathi kwendawo yokungena nokuphumayo.Oku kuvumela izixhobo ukuba zihambe zisihla ngevalve ukusuka kwindawo yokungena ukuya kwindawo yokuphuma ngelixa uthintela ukuhamba komoya.Izinto eziphathekayo zihamba ngokuqhubekayo ngobukho boxinzelelo lomoya rhoqo phakathi kwamazibuko.Olu xinzelelo okanye ukwahlukana kwe-vacuum kufuneka kugcinwe ngaphakathi kwevalve ukwenzela umsebenzi ofanelekileyo.
Ngenxa yeempawu zevalve ejikelezayo, ivalve ejikelezayo isetyenziswa kakhulu phantsi komqokeleli wothuli kunye neSilos njl njl
Iivalvu zokuvala umoya ezijikelezayo zikwabizwa ngokuba zii-rotary feeders, iivalve ezijikelezayo, okanye izitshixo zomoya ezijikelezayo.Isetyenziswa kuzo zombini isitayile soxinzelelo kunye ne-vacuum engalunganga yokuhambisa i-pneumatic system, ngenxa yeempawu zevalve ejikelezayo, ezi zivalo zisebenza "njengesitshixo" ukuthintela ukulahleka komoya ngelixa ngaxeshanye zenza imisebenzi ebalulekileyo yokuphatha izinto.Nangona ilula, ivalve yokuvala umoya ejikelezayo yinxalenye ebalulekileyo yokusebenza kakuhle kwenkqubo yokuhambisa.Kubalulekile ukukhumbula ukuba ayizizo zonke iivalvu eziziivalvu ezijikelezayo - kodwa phantse zonke izitshixo zomoya ezijikelezayo zizivalvu ezijikelezayo.
