1. Isingenisoku-Butterfly Valves
1.1. Incazelo kanye Nemisebenzi Eyisisekelo
A uvemvane valveiyithuluzi elilawula ukugeleza kwepayipi. Ilawulwa ngokuzungezisa idiski ukuphenduka kwekota. Ngokuvamile zisetshenziswa ezinhlelweni lapho zivalwa khona ngokushesha.
1.2. Umlando Wevaveve Butterfly
Ama-valve ovemvane angalandelelwa emuva ngasekupheleni kwekhulu le-19. I-prototype ye-valve ye-butterfly yesimanje yazalwa maphakathi nekhulu lama-20. Ngemva kwamashumi eminyaka yentuthuko, isibe yisixazululo esiguquguqukayo sokulawula imidiya ezimbonini ezihlukahlukene.
Ukuthuthukiswa kwezobuchwepheshe kwamavalve emvemvane akukayeki. Esikhathini esizayo, ama-butterfly valves azoba lula futhi ahlangene. Angasetshenziswa futhi ezimeni ezimbi kakhulu (njengokucindezela okuphezulu kakhulu kanye nezinga lokushisa eliphansi kakhulu). Mhlawumbe angasetshenziswa ezinhlelweni ezintsha emkhakheni wamandla avuselelekayo, njengamandla elanga, amandla omoya kanye namaphrojekthi wamandla e-hydrogen eluhlaza.
1.3. Ukusetshenziswa kwe-Butterfly Valves Ezimbonini Ezihlukahlukene

Amandla abo okusebenza emazingeni okushisa aphezulu kanye nezingcindezi abenza bafanelekele izinhlelo zokusebenza ezifana nokucubungula amakhemikhali, ukugcinwa, kanye nezinhlelo zokudiliva.
1.3.4. Imboni kawoyela negesi
Imboni kawoyela negesi incike kumavalvu ovemvane ukuze isetshenziswe njengokuhlukaniswa kwamapayipi, ukulawula ukugeleza, nezinhlelo zamathangi. Ukuhambisana kwama-butterfly valves anezinhlobonhlobo zezinto ezibonakalayo kuqinisekisa ukusebenza kwabo okuphephile embonini yamafutha negesi.
1.3.5. Ukucubungula Ukudla Neziphuzo
Ukuhlanzeka kuyinto ehamba phambili ekulungiseni ukudla neziphuzo. Amavalvu ovemvane anemiklamo yenhlanzeko nezindawo ezipholishiwe angasetshenziswa ukuze kugcinwe ukuhlanzeka nokuvimbela ukungcoliswa lapho kusingathwa uketshezi olunjengamajusi, imikhiqizo yobisi, neziphuzo. Kokubili irabha eqinisekisiwe ye-wras kanye nensimbi engagqwali yezinga lokudla zingahlangabezana naleli zinga.
1.3.6. I-Marine and Shipbuilding
Amavalvu e-Aluminium bronze butterfly aklanyelwe izinhlelo zokusebenza zasolwandle ukulawula amasistimu e-ballast, amanzi okupholisa, nemigqa yamafutha. Izinto ezikwazi ukumelana nokugqwala zamavalvu ovemvane ziwenza alungele ukusetshenziswa ezindaweni zasolwandle ezinokhahlo.
1.3.7. Izitshalo zamandla
Ezitshalweni zamandla, ama-valve ovemvane asetshenziswa ezinhlelweni zokupholisa, imigqa yesitimu, nezinhlelo ze-flue gas desulfurization. Bayakwazi ukuphatha umfutho ophezulu kanye noketshezi lokushisa eliphezulu.
1.3.8. Izindawo Zokuhlanza Amanzi Angcolile
Amavalvu ovemvane abalulekile ekulawuleni udaka, ukungena komoya, nokugeleza kwamanzi ezindaweni zokuhlanza amanzi angcolile.
1.3.9. Imboni ye-Pulp nephepha
Imboni ye-pulp nephepha izuza ngamavalve ovemvane ezinqubweni ezinjengokupheka kwe-pulp, ukuxubha, nokululama kwamakhemikhali. Ukumelana kwabo ne-abrasive pulp namakhemikhali kwandisa ukusebenza kahle nempilo yesevisi.
2. Ukwakhiwa kwe-Butterfly Valve
