Umhlobo we-wafer
+Ilayitha
+Itjhiphile
+Ukufakwa okulula
-Amafletjhi wamapayipi ayatlhogeka
-Kunzima ukubeka phakathi
-Akukafaneli njengevalvu yokugcina
Endabeni ye-valve ye-butterfly yesitayela se-Wafer, umzimba une-annular eneembobo ezimbalwa ezingakafakwa phakathi. Eminye imihlobo yama-Wafer inamabili kuthi eminye inamane.
Amabhawudo we-flange afakwa ngaphakathi kweembobo zama-flange wamapayipi amabili kanye neembobo eziphakathi kwevalvu ye-butterfly. Ngokuqinisa amabhawudo we-flange, ama-flange wepayipi adonselwa komunye nomunye begodu ivalvu ye-butterfly ivalelwe hlangana nama-flange begodu ibambeke endaweni yayo.
Umhlobo we-lug
+Ilungele njenge-end valve*
+Kulula ukubeka phakathi
+Akuzweli kangako lokha nakunomehluko omkhulu wezinga lokutjhisa
-Ubudisi ngamasayizi amakhulu
-Ibiza khulu
Endabeni ye-lug-style butterfly valve kunezinto ezibizwa ngokuthi "iindlebe" phezu komjikelezo woke womzimba lapho iintambo bezifakwe khona. Ngalendlela, ivalvu ye-butterfly ingaqiniswa kiwo woke amafletjhi amabili wepayipi ngokusebenzisa amabhawudo amabili ahlukileko (elinye ngehlangothini ngalinye).
Ngombana ivalvu ye-butterfly inamathele ku-flange ngayinye emahlangothini womabili ngamabhawudo ahlukileko, amafitjhani, ithuba lokuphumula ngokusebenzisa ukunwebeka kokutjhisa lincani kune-valve yesitayela se-Wafer. Njengomphumela, inguqulo ye-Lug ilungele khulu ukusetjenziswa okunomehluko omkhulu wamazinga womtjhiso.
*Kodwana, lokha i-vavle yesitayela se-Lug nayisetjenziswa njenge-valve yokugcina, umuntu kufanele atjheje ngombana inengi lama-valve we-Lug-style we-butterfly azokuba nomfutho ophasi ovunyelweko njenge-valve yokugcina ukudlula iklasi yawo yomfutho “ojwayelekileko” otjengisako.
