1. I se tulaga lautele, i le fa'aitiitia o le vevela, fa'atonutonuina o le pulea ma le palapala, e mana'omia le fausaga ia pu'upu'u le umi ma vave le saoasaoa o le tatalaina ma le tapunia (1/4 o le taamilosaga). E maualalo le tipiina o le mamafa (ese'esega la'ititi o le mamafa), e fautuaina le butterfly valve.
2. E mafai ona fa'aogaina le valve pepe pe a fetu'una'i tulaga e lua, auala vaapiapi, pisa maualalo, cavitation ma vaporization, sina vaega itiiti o le leakage i le ea, ma ala o faasalalauga abrasive.
3. A faʻaaogaina le butterfly valve i lalo o tulaga faʻapitoa e pei o le fetuʻunaʻiga o le throttling, faʻamaufaʻailogaina faʻamalosi, poʻo le ofuina tele, vevela maualalo (cryogenic), ma isi mea, e tatau ona faʻaaogaina se faʻamaufaʻailoga uʻamea ua mamanuina faʻapitoa ma se masini fetuʻunaʻi e tolu-eccentric poʻo le lua-eccentric. Valve butterfly tuʻufaʻatasi mo le eleele.
4. O le valve butterfly line centerline e talafeagai mo vai fou, otaota, vai sami, vai masima, ausa, kesi masani, mea'ai, vaila'au, ma le suau'u e mana'omia le fa'amaufa'ailogaina atoatoa, leai se su'ega o le kesi e tafe, mana'oga maualuga mo le ola, ma le vevela o le galue e -10℃ ~ 150℃. Ma paipa eseese e pei o le 'acid' ma le 'alkali' ma isi paipa.
5. O le valve pepeti eccentric e malu-fa'amaufa'ailogaina e fetaui lelei mo le tatalaina ma le tapunia i itu e lua ma le fetu'una'iga o paipa e fa'aoso ai le ea ma le aveeseina o le pefu. E fa'aaogaina lautele i paipa kesi ma alavai i u'amea, alamanuia mama, eletise, ma faiga petrochemical.
6. O le uaea uʻamea-i-uʻamea e faʻamaufaʻailogaina ai le valve pepe eccentric faʻalua e talafeagai mo le faʻavevela i le taulaga, kesi, sapalai o le vai ma isi paipa kesi, suauʻu, acid ma alkali, e fai ma masini faʻatonutonu ma faʻalavelave.
7. I le fa'aopoopoga i le fa'aaogaina o se polokalame tele o le pressure swing adsorption (PSA) kesi vavae'ese polokalame valve, o le metal-to-metal seal triple eccentric butterfly valve e mafai foi ona fa'aaogaina lautele i le suau'u, petrochemicals, kemikolo, metallurgical, eletise ma isi vaega. O se gate valve ma se stop valve. O se isi oloa lelei.
O Nortech o se tasi o kamupani gaosi valve tau alamanuia taʻutaʻua i Saina ma le tusipasi lelei ISO9001.
