Ka kakaretso, taolong le taolong ea seretse, bolelele bo khuts'oane ba sebopeho le lebelo la ho bula le ho koala kapele (1 / 4 turn) lia hlokahala.Khatello e fokolang ea khatello e tlaase (khatello e nyenyane ea phapang), valve ea serurubele e khothalletsoa.

Li-valve tsa butterfly li ka khethoa haeba ho na le taolo ea maemo a mabeli, mocha oa fatše o nang le molala, lerata le tlaase, cavitation le gasification, ho lutla ho honyenyane ho ea sepakapakeng le bohareng ba abrasive.

Ha valve ea serurubele e sebelisoa tlas'a maemo a khethehileng a ho sebetsa, joalo ka taolo ea throttling, litlhoko tse tiileng tsa ho tiisa, kapa ho apara ka matla, mocheso o tlaase (cryogenic) le maemo a mang a ho sebetsa, hoa hlokahala ho sebelisa li-valve tse khethehileng tse tharo kapa tse peli tse nang le serurubele se khethehileng. e etselitsoeng tiiso ea tšepe le sesebelisoa sa ho laola.

Sesepa sa serurubele se bohareng se sebetsa ho metsi a hloekileng, likhoerekhoere, metsi a leoatle, brine, mouoane, khase ea tlhaho, lijo, meriana, lihlahisoa tsa oli, acid e fapaneng le alkali le liphaephe tse ling tse hlokang ho tiisoa ka ho feletseng, ho lutla ha tlhahlobo ea khase ea zero, bophelo ba tšebeletso e phahameng le mocheso o sebetsang. ea – 10 ℃ ~ 150 ℃.

Soft seal eccentric butterfly valve e loketse ho buloa ka litsela tse peli, ho koala le ho lokisa moea le phaephe ea ho tlosa lerōle.E sebelisoa haholo liphaepheng tsa khase le mocha oa metsi oa metallurgy, indasteri e khanyang, matla a motlakase le tsamaiso ea petrochemical.

Metal to metal e tiisitsoeng habeli eccentric butterfly valve e loketse ho futhumala ha litoropo, phepelo ea khase, phepelo ea metsi le khase e 'ngoe, oli, acid-base le liphaephe tse ling e le sesebelisoa se laolang le ho thetheha.
