Mavavu a butterfly ndi oyenera kuyendetsa kayendedwe.Chifukwa kuthamanga kwa valavu ya gulugufe mu payipi kumakhala kwakukulu, pafupifupi katatu kuposa valavu ya chipata, posankha valavu ya butterfly, chikoka cha dongosolo la payipi ndi kutayika kwa mphamvu kuyenera kuganiziridwa bwino, ndi kulimba kwa valve. Gulugufe mbale kupirira kupanikizika kwa sing'anga mapaipi ayenera kuganiziridwa pamene chatsekedwa.kugonana.Kuphatikiza apo, kuchepa kwa kutentha kwa zinthu zapampando wa elastomeric pamatenthedwe okwera kuyeneranso kuganiziridwa.

Kutalika kwa kapangidwe ndi kutalika konse kwavalavu ya butterflyndi ang'onoang'ono, kutsegula ndi kutseka liwiro mofulumira, ndipo ali ndi makhalidwe abwino kulamulira madzimadzi.Kapangidwe ka valavu ya gulugufe ndi yabwino kwambiri popanga ma valve akulu akulu.Pamene avalavu ya butterfly imayenera kugwiritsidwa ntchito poyendetsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Nthawi zambiri, pakuwongolera, kuwongolera ndi matope apakati, kutalika kwa kapangidwe kafupi komanso kutsegulira ndi kutseka mwachangu (1/4r) ndikofunikira.Kuchepetsa kuthamanga kwapakati (kuthamanga kochepa kosiyana), vavu ya butterfly ndiyofunikira.Valve ya butterflyangagwiritsidwe ntchito pawiri udindo kusintha, yopapatiza njira, phokoso otsika, cavitation ndi gasification, pang'ono kutayikira mlengalenga, ndi sing'anga abrasive.

The concentric valavu ya butterfly ndi oyenera madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi, chakudya, mankhwala, mafuta ndi osiyanasiyana Acid-m'munsi ndi mapaipi ena.

Vavu yagulugufe yofewa yosindikizidwa ndi oyenera njira ziwiri kutsegula ndi kutseka ndi kusintha mpweya ndi fumbi kuchotsa mapaipi ndipo chimagwiritsidwa ntchito mapaipi mpweya ndi madzi zitsulo, makampani kuwala, mphamvu yamagetsi, ndi petrochemical kachitidwe.
