Vavu yagulugufe yamagetsi ya flange nthawi zambiri imakhala ndi makina opangira magetsi ozungulira (0-90 digiri pang'ono kasinthasintha) ndi valavu yagulugufe kudzera pamakina olumikizira, pambuyo pa kukhazikitsa ndi kukonza zolakwika.

Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera. Mu ndime yozungulira ya thupi lagulugufe, mbale yagulugufe ya disc imazungulira mozungulira, ndipo ngodya yozungulira imakhala pakati pa 0 ~ 90. Pamene ngodya yozungulira ili pakati pa 0 ~ 90, valve imatsegulidwa kwathunthu.

Valve ya gulugufe ndi yophweka popanga, yaying'ono mu voliyumu ndi yopepuka kulemera kwake, ndipo imakhala ndi magawo ochepa chabe. Vavu imatha kuyatsidwa ndikuzimitsa mwachangu pongozungulira madigiri 90. Ntchitoyi ndi yosavuta ndipo valavu ili ndi makhalidwe abwino olamulira madzimadzi.

Gulugufe mbale ya magetsi flange gulugufe valavu imayikidwa mu m'mimba mwake mbali ya payipi. Mu ndime yozungulira ya thupi lagulugufe, mbale yagulugufe ya disc imazungulira mozungulira, ndipo ngodya yozungulira imakhala pakati pa 0 ~ 90. Pamene ngodya yozungulira ili pakati pa 0 ~ 90, valve imatsegulidwa kwathunthu.

Valavu yagulugufe yamagetsi ya flange ndiyosavuta kupanga, yaying'ono mu voliyumu komanso yopepuka kulemera, ndipo imakhala ndi magawo ochepa chabe. Vavu imatha kuyatsidwa ndikuzimitsa mwachangu pongozungulira madigiri 90. Ntchitoyi ndi yosavuta ndipo valavu ili ndi makhalidwe abwino olamulira madzimadzi. Pamene flange gulugufe valavu ali zonse lotseguka udindo, gulugufe mbale makulidwe ndi kukana yekha pamene sing'anga umayenda mwa valavu thupi, kotero kuthamanga dontho kwaiye valavu ndi laling'ono kwambiri, choncho ali bwino otaya kulamulira makhalidwe. Vavu ya butterfly imakhala ndi chisindikizo chotanuka komanso chisindikizo chachitsulo. Vavu yosindikizira yokhazikika, mphete yosindikizira imatha kuyikidwa mu valavu kapena kumangirizidwa ku mbale yagulugufe.

Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa omwe amakhala ndi zisindikizo zotanuka, koma ndizovuta kuti asindikize kwathunthu. Chisindikizo chachitsulo chimatha kutengera kutentha kwapamwamba kogwira ntchito, pomwe chisindikizo chotanuka chimakhala ndi vuto la kuchepetsa kutentha.

Ngati valavu ya butterfly ikufunika kuti igwiritsidwe ntchito ngati kayendetsedwe ka kayendedwe kake, chinthu chachikulu ndikusankha kukula koyenera ndi mtundu wa valve. Mapangidwe ndi mfundo ya valavu ya butterfly ndi yabwino kwambiri popanga valavu yayikulu. Mavavu agulugufe samangogwiritsidwa ntchito kwambiri mumafuta, gasi, makampani opanga mankhwala, mankhwala amadzi ndi mafakitale ena onse, komanso amagwiritsidwa ntchito m'madzi ozizira amagetsi opangira magetsi.

Mavavu agulugufe omwe amagwiritsidwa ntchito kwambiri ndi ma valve a butterfly ndi ma valve a butterfly. Vavu yagulugufe wothina amalumikizidwa pakati pa mapiipi awiri opindika ndi ma bawuti amitu iwiri. Vavu ya butterfly ya flange imakhala ndi ma flanges pa valve. Ma flanges pa malekezero onse a valavu amalumikizidwa ndi mapaipi a mapaipi ndi mabawuti.

Pamalo otseguka, makulidwe a gulugufe ndiokhawo omwe amakana pomwe sing'anga imayenda kudzera mu valavu, kotero kutsika kwamphamvu komwe kumapangidwa ndi valavu kumakhala kochepa kwambiri, kotero kumakhala ndi mawonekedwe abwino owongolera. Vavu ya butterfly imakhala ndi chisindikizo chotanuka komanso chisindikizo chachitsulo. Vavu yosindikizira yokhazikika, mphete yosindikizira imatha kuyikidwa mu valavu kapena kumangirizidwa ku mbale yagulugufe.

Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa omwe amakhala ndi zisindikizo zotanuka, koma ndizovuta kuti asindikize kwathunthu. Chisindikizo chachitsulo chimatha kutengera kutentha kwapamwamba kogwira ntchito, pomwe chisindikizo chotanuka chimakhala ndi vuto la kuchepetsa kutentha.

Ngati valavu ya butterfly ikufunika kuti igwiritsidwe ntchito ngati kayendetsedwe ka kayendedwe kake, chinthu chachikulu ndikusankha kukula koyenera ndi mtundu wa valve. Kapangidwe ka valavu ya butterfly ndi yabwino kwambiri popanga ma valve akulu akulu. Mavavu agulugufe samangogwiritsidwa ntchito kwambiri mumafuta, gasi, makampani opanga mankhwala, mankhwala amadzi ndi mafakitale ena onse, komanso amagwiritsidwa ntchito m'madzi ozizira amagetsi opangira magetsi.

Mavavu agulugufe omwe amagwiritsidwa ntchito kwambiri ndi ma valve a butterfly ndi ma valve a butterfly. Vavu yagulugufe wothina amalumikizidwa pakati pa mapiipi awiri opindika ndi ma bawuti amitu iwiri. Vavu ya butterfly ya flange imakhala ndi ma flanges pa valve. Ma flanges pa malekezero onse a valavu amalumikizidwa ndi mapaipi a mapaipi ndi mabawuti.
