Umoyaivelufa butterflyluhlobo lwevalvu yokulawula esetyenziswa ngokubanzi kwimibhobho yoshishino. Icandelo layo eliphambili liyi-disc-shaped disc efakwe kumbhobho kwaye ijikeleze kwi-axis yayo. Xa i-disc ijikeleza i-90 degrees, i-valve ivala; Xa ujikelezwe nge-0 degrees, i-valve ivula.

Umgaqo osebenzayo we-pneumatic steel stainless butterfly valve kukulawula ukujikeleza kwepleyiti yebhabhathane nge-actuator yomoya. I-actuator ye-pneumatic ifumana umoya ocinezelweyo njengomthombo wamandla, kwaye iqhube i-butterfly plate ukuvula okanye ukuvala ngokweemfuno zesignali yokulawula. Le ndlela yokuqhuba yenza i-valve yebhabhathane ye-pneumatic ineenzuzo zesantya sokuphendula ngokukhawuleza, ukuchaneka kokulawula okuphezulu, ukusebenza okulula kunye nokunye.

Iivalve zebhabhathane zepneumatic zisetyenziswa kakhulu kwiindawo zoshishino. Isetyenziselwa ikakhulu ukulungelelanisa izinga lokuhamba kunye noxinzelelo lwe-medium, kunye nokufezekisa ukusika kunye nokudibanisa umbhobho. Ngenxa yesakhiwo sayo esilula, ubungakanani obuncinci kunye nobunzima obulula, ivalve yebhabhathane ye-pneumatic eccentric inokusebenza kakuhle kokuhamba kwenkqubo yombhobho, enokunciphisa ukumelana nolwelo kunye nokusetyenziswa kwamandla. Ukongeza, i-pneumatic 4 Intshi yebhabhathane ivelufa inokumelana nokugqwala okuhle kunye nokumelana nobushushu obuphezulu, kwaye iyakwazi ukuziqhelanisa neemeko ezahlukeneyo ezinzima.

Iivalvu zebhabhathane zomoya zisetyenziswa kwiindawo ezininzi zoshishino, njengepetrochemical, amandla ombane, isinyithi, amayeza, ukutya njalo njalo. Kwishishini le-petrochemical, iivalvu zebhabhathane zepneumatic zihlala zisetyenziswa kwinkqubo yemibhobho yeoli ekrwada, i-oyile esulungekisiweyo, izinto ezikrwada zeekhemikhali kunye neminye imithombo yeendaba. Kwishishini lamandla, iivalve zebhabhathane zepneumatic zisetyenziswa ikakhulu kwimibhobho yokuhambisa amanzi okupholisa, igesi yepetroli kunye neminye imithombo yeendaba kwizityalo zamandla. Kwishishini le-metallurgical, iivalve zebhabhathane zepneumatic zisetyenziswa kwiinkqubo zombhobho ezinobushushu obuphezulu besinyithi esinyibilikisiweyo kunye nezinye imidiya.

Ngamafutshane, i-valve ye-butterfly ye-pneumatic idlala indima ebalulekileyo kwi-industrial pipeline system kunye nesakhiwo sayo esisodwa kunye nomgaqo wokusebenza. Ayinakufikelela kuphela kulawulo oluchanekileyo lokuhamba okuphakathi kunye noxinzelelo, kodwa inokumelana ne-corrosion elungileyo kunye nokumelana nobushushu obuphezulu, ngoko isetyenziswa kakhulu kwiinkalo ezahlukeneyo zoshishino.
