Afai e sili atu i le DN600, e mafai ona e filifilia se valve butterfly tasi (DN700-DN1000). Fa'aopoopo lapo'a tetele (pei o luga DN1200) e seasea ona o le maualuga fa'apipi'i ma fa'amaufa'ailoga mana'oga.
2. Fa'ato'a lua flange butterfly valve
- Vaitafe va'aiga: DN50–DN3000
- Fa'amatalaga: E fetaui lelei le valve flange flange mo taimi e mana'omia ai le mautu maualuga ma le fa'amaufa'ailoga. E i ai le lautele lautele lautele ma e masani ona faʻaaogaina i faiga paipa tetele e pei o vai vai, nofoaga eletise, ma isi.
3. Fa'alava lele lele tasi
- Diamita lautele: DN700–DN1000
- Fa'amatalaga: Fa'ato'a fa'alava fa'alava fa'au'u e tasi e fa'aaoga ai mea e itiiti ifo nai lo fa'alava fa'ato'a lua po'o lug valve, lea e fa'aitiitia ai tau o le gaosiga ma fa'aitiitia ai foi tau o felauaiga. O lo'o fa'amauina i le au paipa ma fa'amau i totonu.
4. Fa'alava lele lele
- Vaitafe va'aiga: DN50–DN600
- Fa'amatalaga: Fa'alava lele (Lug type) e fetaui lelei mo faiga i le pito o le paipa po'o le mana'omia o le fa'ate'a soo. O le lautele lautele e laʻititi ma feololo. Ona o tapulaʻa faʻatulagaina, o faʻaoga lautele lautele e le masani ai.
5. U-ituaiga butterfly valve
- Caliber laina: DN100–DN1800
- Faʻamatalaga: U-ituaiga butterfly valves e masani ona faʻaaogaina mo paipa tetele-diameter, e pei o le tuʻuina atu o vai a le malo, faʻamaʻi otaota, ma isi, ma o le fausaga e talafeagai mo le maualuga o le tafe ma le maualalo o vaʻaiga o le eseesega.
| Fa'amatalaga | Lapata'iga masani (DN) | Fa'amatalaga Autu |
|---|---|---|
| Valve Pepe Vai | DN15-DN600 | Faʻapipiʻi faʻapipiʻi, taugofie, faʻaaogaina lautele i faiga faʻamalosi maualalo; lapopoa tetele mo auaunaga le taua. |
| Lug Butterfly Valve | DN50-DN600 | Talafeagai mo auaunaga mate-mate ma faiga e manaomia le disassembly mai le tasi itu. E sili atu le lelei o le taulimaina o le mamafa nai lo le ituaiga vai. |
| Valve Pepepe Tasi-Flanged | DN700-DN1000 | E masani i faiga tanu pe maualalo-oomi; mama mama ma faigofie ona faʻapipiʻi. |
| Valve Pepe Fa'alua-Flanged | DN50-DN3000(e oo atu i le DN4000 i nisi tulaga) | E fetaui mo le maualuga-omiga, tele-diameter, ma faʻaoga taua; sili ona lelei fa'amaufa'ailoga. |
| Valve Pepe U-ituaiga | DN50-DN1800 | E masani lava ona pa'u laina po'o laina atoa mo le pala i auaunaga tau vaila'au. |

2. Caliber le tele o valve butterfly fa'avasegaina i le ituaiga fausaga
1. Centerline butterfly valve
- Caliber laina: DN50–DN1200
- Faʻamatalaga: Centerline butterfly valve (faʻamaufaʻailoga vaivai poʻo faʻamaufaʻailoga faʻamau) ei ai se fausaga faigofie, e fetaui mo le maualalo o le mamafa ma le masani o le vevela alalaupapa, faʻaogaina o le caliber, ma faʻaaogaina lautele i vai, kesi ma isi faiga.
2. Valau pepe fa'ailoga fa'alua
- Caliber laina: DN50–DN1800
- Faʻamatalaga: Faʻamaufaʻailoga butterfly valve faʻalua e faʻaitiitia ai le faʻamaufaʻailoga e ala i le mamanu faʻapitoa, e talafeagai mo faiga maualalo ma feololo, e iai le lautele lautele, ma e masani ona faʻaaogaina i le suauu ma le kesi, vailaʻau ma isi pisinisi.
3. Valau pepe fa'ailoga tolu
- Caliber laina: DN100–DN3000
- Fa'amatalaga: Triple eccentric butterfly valve (fa'amaufa'ailoga malo) e fetaui lelei mo le maualuga o le vevela, maualuga le mamafa ma tulaga faigaluega faigata. O loʻo i ai le tele o caliber ma e masani ona faʻaaogaina i paipa tetele o fale gaosi oloa, e pei o le eletise, petrochemical, ma isi.
| Fa'amatalaga | Laisene masani | Fa'amatalaga Autu |
|---|---|---|
| Valve Butterfly Concentric | DN40-DN1200 (e oʻo atu i le DN2000 i nisi tulaga) | Po'a ma tisiki laina ogatotonu o lo'o fa'aogatotonu le nofo malu e talafeagai mo le mamafa maualalo, fa'aoga lautele. |
| Valve Butterfly Seti Faalua | DN100-DN2000 (e oo atu i le DN3000) | E vave alu ese le tisiki mai le nofoa i luga o le avanoa e faʻaitiitia ai le ofuina, faʻaaogaina i tulaga feololo. |
| Valve Pepepe Tolu Offset | DN100-DN3000 (e oo atu i le DN4000) | Fuafuaina mo le maualuga, maualuga-omiga, leai-leakage talosaga, masani-nofoa uamea. |
