Ama-valve e-butterfly afanele ukulawulwa kokugeleza. Njengoba ukuncipha komfutho we-valve uvemvane epayipini kukhulu uma kuqhathaniswa, cishe okuphindwe kathathu kune-valve yesango, lapho kukhethwa i-valve uvemvane, ithonya lokulahlekelwa kwengcindezi ohlelweni lwamapayipi kufanele licatshangelwe ngokugcwele, nokuqina kwepuleti uvemvane eliphethe ipayipi lokucindezela okuphakathi lapho livala kufanele futhi kucatshangelwe. Ngaphezu kwalokho, umkhawulo wokushisa osebenzayo wezinto zokuhlala ezinwebekayo ekushiseni okuphezulu kufanele ucatshangelwe.

I-valve yovemvane inobude obuncane besakhiwo nobude bayo yonke, isivinini sokuvula nokuvala ngokushesha, nezici ezinhle zokulawula uketshezi. Isimiso sesakhiwo se-valve ye-butterfly ifaneleka kakhulu ekwenzeni ama-valve amakhulu. Lapho i-valve ye-butterfly idingeka ukulawula ukugeleza, into ebaluleke kakhulu ukukhetha kahle ubukhulu kanye nohlobo lwe-valve butterfly ukuze lusebenze kahle nangempumelelo.

Imvamisa, ekulawuleni ukudonsa nokulawula kanye nodaka oluphakathi, ubude besakhiwo esifushane kanye nesivinini sokuvula nokuvala (i-1/4 turn) kuyadingeka. I-valve yokusika ingcindezi ephansi (ingcindezi encane yokuhlukanisa), i-valve uvemvane iyanconywa.

I-valve ye-Butterfly ingakhethwa uma kulawulwa isikhundla esiphindwe kabili, isiteshi somhlaba esinentamo, umsindo ophansi, i-cavitation kanye ne-gasification, ukuvuza okuncane emkhathini kanye ne-abrasive medium.

Lapho i-valve ye-butterfly isetshenziswa ngaphansi kwezimo ezikhethekile zokusebenza, njengokulawulwa kwe-throttling, izidingo eziqinile zokuvalwa, noma ukuguga okuqinile, izinga lokushisa eliphansi (cryogenic) nezinye izimo zokusebenza, kuyadingeka ukusebenzisa i-valve ye-butterfly eccentric eccentric noma kabili ene-eccentric ene-metal eklanyelwe ngokukhethekile kanye nedivaysi yokulawula.

Ivalve yovemvane ephakathi nendawo isebenza emanzini ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, imikhiqizo kawoyela, i-asidi ehlukahlukene kanye ne-alkali namanye amapayipi adinga ukubekwa uphawu okuphelele, ukuvuza kokuhlolwa kwegesi okuyiziro, impilo yesevisi ephezulu kanye nezinga lokushisa lokusebenza elingu-10 ℃ ~ 150 ℃.

I-valve uvemvane oluthambile uphawu oluthambile ilungele ukuvulwa okubili, ukuvala nokulungiswa kwepayipi lokungena komoya kanye nokukhipha uthuli. Isetshenziswa kabanzi epayipini legesi kanye nesiteshi samanzi se-metallurgy, imboni yokukhanya, amandla kagesi kanye nohlelo lwe-petrochemical.

I-valve uvemvane oluyinsimbi ukuya ensimbi oluvalwe kabili lufanele ukushisisa kwasemadolobheni, ukuhlinzekwa kwegesi, ukuhlinzekwa kwamanzi kanye nenye igesi, uwoyela, isisekelo se-asidi namanye amapayipi njengesisetshenziswa esilawulayo nesiphundu.
