1. Ngokujwayelekile, ekushayeni, ekulawuleni nasekulawuleni udaka, isakhiwo sidingeka sibe sifushane ngobude futhi sisheshe ekuvuleni nasekuvaleni isivinini (1/4 revolution).I-low pressure cut-off (umehluko omncane wengcindezi), i-valve uvemvane iyanconywa.
2. I-valve ye-butterfly ingasetshenziswa lapho ukulungiswa kwezindawo ezimbili, ukuhamba okuncane, umsindo ophansi, i-cavitation kanye ne-vaporization, inani elincane lokuvuza emkhathini, kanye nemidiya ehlukumezayo.
3. Lapho i-valve ye-butterfly isetshenziswa ngaphansi kwezimo ezikhethekile ezifana nokulungiswa kwe-throttling, ukuvalwa okuqinile, noma ukuguga okuqinile, izinga lokushisa eliphansi (cryogenic), njll., kuyadingeka ukusebenzisa uphawu lwensimbi oluklanyelwe ngokukhethekile nge-three-eccentric noma kabili- I-eccentric yokulungisa i-valve yevemvane enikezelwe emhlabathini.
4. I-centerline butterfly valve ifanele amanzi ahlanzekile, indle, amanzi olwandle, amanzi anosawoti, umusi, igesi yemvelo, ukudla, imithi, namafutha adinga ukuvalwa okuphelele, ukuvuza kwegesi eyiziro, izidingo zokuphila eziphakeme, kanye nezinga lokushisa lokusebenza - 10 ℃ ~ 150 ℃.Futhi i-asidi ehlukahlukene kanye ne-alkali namanye amapayipi.
5. I-valve uvemvane evalwe ngokuthambile eccentric ifanele ukuvuleka nokuvala ngezindlela ezimbili kanye nokulungiswa kwamapayipi okungenisa umoya nokukhipha uthuli.Isetshenziswa kabanzi kumapayipi egesi nasemigwaqweni yamanzi kwezensimbi, imboni yokukhanya, amandla kagesi, kanye nezinhlelo ze-petrochemical.
6. I-valve ye-butterfly ene-eccentric ephindwe kabili ye-metal-to-metal ifanele ukushisisa kwasemadolobheni, igesi, ukuphakelwa kwamanzi namanye amapayipi egesi, uwoyela, i-asidi kanye ne-alkali, njengesisetshenziswa esilawulayo nesinyakazisayo.
7. Ngaphezu kokusetshenziswa njenge-valve yokulawula uhlelo lwedivayisi yokuhlukanisa igesi yokucindezela okukhulu kwe-swing swing adsorption (PSA), i-valve uvemvane we-metal-to-metal seal eccentric eccentric ingasetshenziswa kabanzi ku-petroleum, petrochemical, chemical, metallurgical, amandla kagesi nezinye izinkambu.Kuyi-valve yesango kanye ne-stop valve.Umkhiqizo ohlukile omuhle.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
