Iivalve zebhabhathane zilungele imibhobho ehambisa izinto zolwelo ezahlukeneyo ezidlekayo nezingadlekiyo kwiinkqubo zobunjineli ezifana nerhasi yamalahle, irhasi yendalo, irhasi yepetroleum elulwelo, igesi yesixeko, umoya oshushu nobandayo, ukunyibilikiswa kweekhemikhali, ukuveliswa kombane kunye nokhuseleko lokusingqongileyo, kwaye zisetyenziselwa ukulungisa nokunqamla ukuhamba kwemithombo yeendaba.
Iivalve zebhabhathane zifanelekile kulawulo lokuhamba. Ngenxa yokuba ilahleko yoxinzelelo lwevalve yebhabhathane kumbhobho inkulu ngokwentelekiso, malunga nokuphinda kathathu kwevalve yesango, xa kukhethwa ivalve yebhabhathane, impembelelo yenkqubo yombhobho ngokulahleka koxinzelelo kufuneka iqwalaselwe ngokupheleleyo, kunye nokuqina kwepleyiti yebhabhathane ukumelana noxinzelelo lwendlela yombhobho nayo kufuneka iqwalaselwe xa ivaliwe. ngesondo. Ukongeza, imida yobushushu obusebenzayo bezinto zokuhlala ze-elastomeric kumaqondo obushushu aphakamileyo kufuneka kuqwalaselwe.
Ubude besakhiwo kunye nokuphakama ngokubanzi kweivalve yebhabhathanezincinci, isantya sokuvula kunye nokuvala sikhawuleza, kwaye sineempawu ezilungileyo zokulawula ulwelo. Umgaqo-siseko wevalve yebhabhathane yeyona ifanelekileyo ukwenza iivalve ezinobubanzi obukhulu. Xa iivelufa butterfly iyadingeka ukuba isetyenziswe ukulawula ukuhamba, eyona nto ibalulekileyo kukukhetha ngokuchanekileyo ubungakanani kunye nohlobo lwevalve yebhabhathane ukuze isebenze ngokufanelekileyo nangempumelelo.
Ngokuqhelekileyo, kwi-throttling, ulawulo olulawulayo kunye nodaka oluphakathi, ubude obufutshane besakhiwo kunye nokuvula ngokukhawuleza kunye nokuvala isantya (1/4r) kuyadingeka. Ukunqunyulwa koxinzelelo oluphantsi (uxinzelelo oluncinci oluhlukileyo), ivalve yebhabhathane iyacetyiswa.Ivalve yebhabhathaneingasetyenziselwa ukulungiswa kweendawo ezimbini, umjelo onqamlekileyo, ingxolo ephantsi, i-cavitation kunye ne-gasification, inani elincinci lokuvuza emoyeni, kunye ne-abrasive medium.
I ci-ocentric ivelufa butterfly ilungele amanzi amatsha, ugutyulo, amanzi olwandle, amanzi anetyuwa, umphunga, igesi yendalo, ukutya, amayeza, i-oyile kunye ne-Acid-base eyahlukeneyo kunye neminye imibhobho.
Ivalve yebhabhathane etywiniweyo ethambileyo ilungele ukuvulwa kunye nokuvala iindlela ezimbini kunye nokulungelelaniswa kwemibhobho yokuphuma komoya kunye nokususa uthuli kwaye isetyenziswa ngokubanzi kwimibhobho yegesi kunye neendlela zamanzi zesinyithi, ishishini lokukhanya, amandla ombane kunye neenkqubo zepetrochemical.
