O le tele ma le tele o vaʻa Saina o loʻo faʻatau atu i atunuʻu eseese i le salafa o le lalolagi, ona le malamalama lea o le tele o tagata faʻatau mai fafo i le taua o le numera o le valve a Saina, i aso nei o le a matou ave oe i se malamalamaga patino, faʻamoemoe e mafai ona fesoasoani ia matou tagata faʻatau.
I Saina, o ituaiga o valve ma mea e sili atu ma sili atu, o le sauniuniga o faʻataʻitaʻiga valve e sili atu ma sili atu ona faigata;faʻataʻitaʻiga valve e tatau ona masani ona faʻaalia le ituaiga valve, auala faʻaulu, fomu fesoʻotaʻiga, foliga faʻatulagaina, faʻamaufaʻailogaina, mea faʻamaufaʻailogaina, mea faʻapipiʻi tino ma isi elemene.Valve faʻataʻitaʻiga faʻataʻitaʻiga o le valve design, filifiliga, tufatufaina atu, e maua ai se auala faigofie e faʻatagaina ai tagata e vaʻavaʻai i le nameplate o le a iloa le fausaga o se ituaiga o valve, meafaitino ma foliga.

Le matafaioi o le iloagofie o valve
Valve faʻailoa i le leai o valve ata, leiloa le nameplate ma valve vaega e le atoatoa, o le faʻaoga saʻo o valve, faʻapipiʻiina vaega valve, toe faʻaleleia ma le suia o vaega valve e taua.O le taimi nei o le faʻailoga o le valve, faʻamatalaga o mea ma le faʻamaonia o le valve o loʻo faʻamatalaina i lalo:
O le faʻaaogaina o le "malamalama masani o le valve" na aʻoaʻoina le malamalama, e tusa ai ma le igoa ma le logo i luga o le valve ma le valve i luga o le lanu vali.E mafai ona e iloa saʻo le vaega o le valve, fausaga faʻapipiʻi, meafaitino, numera numera, faʻamaualuga (poʻo galuega mamafa), faʻasalalauga fetuutuunai, vevela ma tapuni taʻiala.
1.O lo'o fa'amauina le igoa i luga o le tino valve po'o le uili lima.O faʻamatalaga i luga o le nameplate e sili atu ona atoatoa ma faʻaalia uiga autu o le valve.E tusa ai ma le gaosiga i luga o le nameplate, i le gaosi oloa mo le valve ofuina vaega o ata ma faʻamatalaga;e tusa ai ma le aso o le falegaosimea o faʻamatalaga i le toe faaleleia;e tusa ai ma le nameplate o loʻo tuʻuina atu ai tulaga o le faʻaogaina, e fuafua ai le suia o gaskets, mea faʻapipiʻi valve ma fomu faʻapea foi ma le fuafuaina o le suia o isi vaega valve o mea.
2.Fa'ailoga o lo'o fa'aogaina le tu'uina atu, tusi ma isi metotia i totonu o le valve tino e fa'ailoga ai le valve nominal pressure, galuega mamafa, numera numera ma le vaeluaga o le tafega.
3.Valve o loʻo i ai se ituaiga o faʻailoga tatala-tapuni faʻatonuga, ua tatalaina le fua o le pule pe faʻaalia le tatalaina ma le tapunia o le aū.Fa'amau fa'amau, va'a pogisa o le faitoto'a o lo'o fa'ailogaina ma fa'atonuga sui i le pito i luga o le uili lima o lo'o fa'ailogaina ma se aū e fa'asino i le itu o le tapuni-tapuni.
