Mpweyavalavu ya butterflyndi mtundu wa valavu yowongolera yomwe imagwiritsidwa ntchito kwambiri pamapaipi amakampani. Chigawo chake chachikulu ndi chimbale chokhala ngati chimbale chomwe chimayikidwa mu chitoliro ndikuzungulira pa axis yake. Pamene diski ikuzungulira madigiri 90, valve imatseka; Mukazungulira madigiri 0, valavu imatsegulidwa.

Mfundo yogwirira ntchito ya valavu yagulugufe ya chitsulo chosapanga dzimbiri ndikuwongolera kuzungulira kwa mbale yagulugufe kudzera pa cholumikizira chibayo. The actuator pneumatic amalandira wothinikizidwa mpweya ngati gwero la mphamvu, ndipo amayendetsa gulugufe mbale kutsegula kapena kutseka malinga ndi zofunikira za ulamuliro chizindikiro. Njira yoyendetsera iyi imapangitsa kuti valavu ya butterfly ya pneumatic ikhale ndi ubwino wothamanga mofulumira, kulondola kwapamwamba, ntchito yosavuta ndi zina zotero.

Ma valve agulugufe a pneumatic amagwiritsidwa ntchito kwambiri m'mafakitale. Amagwiritsidwa ntchito kwambiri kuti asinthe kuthamanga ndi kuthamanga kwa sing'anga, komanso kukwaniritsa kudula ndi kulumikiza payipi. Chifukwa cha mawonekedwe ake osavuta, kukula kwake kochepa komanso kulemera kwake, valavu ya butterfly ya pneumatic eccentric imakhala ndi kayendedwe kabwino ka kayendedwe ka mapaipi, omwe amatha kuchepetsa kukana kwamadzimadzi ndi kugwiritsa ntchito mphamvu. Kuphatikiza apo, valavu ya butterfly ya pneumatic 4 Inch ilinso ndi kukana kwa dzimbiri komanso kukana kutentha kwambiri, ndipo imatha kutengera madera ovuta.

Ma valve agulugufe a pneumatic amagwiritsidwa ntchito m'mafakitale ambiri, monga petrochemical, mphamvu yamagetsi, zitsulo, mankhwala, chakudya ndi zina zotero. M'makampani a petrochemical, ma valve agulugufe a pneumatic amagwiritsidwa ntchito nthawi zambiri pamapaipi amafuta osakanizidwa, mafuta oyengedwa, zida zamagetsi ndi media zina. M'makampani amagetsi, mavavu agulugufe a pneumatic amagwiritsidwa ntchito kwambiri pamapaipi otumizira madzi ozizira, gasi wamafuta ndi media zina m'mafakitale amagetsi. M'makampani opanga zitsulo, mavavu agulugufe a pneumatic amagwiritsidwa ntchito popanga mapaipi okhala ndi zitsulo zosungunuka ndi kutentha kwambiri.

Mwachidule, valavu ya butterfly ya pneumatic imagwira ntchito yofunika kwambiri pamapaipi a mafakitale ndi mapangidwe ake apadera komanso mfundo zogwirira ntchito. Iwo sangakhoze kukwaniritsa kulamulira olondola otaya sing'anga ndi kuthamanga, komanso ali ndi kukana zabwino dzimbiri ndi kukana kutentha kwambiri, choncho chimagwiritsidwa ntchito m'madera osiyanasiyana mafakitale.
