Fa'apipi'i Fa'amea Fa'amea mo Valve
1. Va'aiga lautele o oloa
Mea: graphite fe'avea'i mama (mea fa'amau -mea fa'atusa)
Fa'atulagaga: Fa'ailoga 'a'ai tulaga ese i luga
Fuafuaga Faamoemoega: Mo le vaega o le gland o alalaupapa falegaosimea, pamu, masini taamilo
Taua Autu: Faʻamaufaʻailoga sili ona lelei, umi le tautua, faʻapipiʻi faigofie; fa'aulu -au'au, maualuga le vevela/tete'e; sui lelei mo packings masani (asbestos, PTFE) i talosaga manaomia
2. Vaega Autu & Fa'amanuiaga
Fa'amaufa'ailoga Fa'atino: Fa'apipi'i graphite e fetaui lelei le a'a o le valve & pusa pusa puipui lelei; fa'amauina lelei le fa'amaufa'ailogaina i lalo o le fesuisuia'i o le mamafa po'o le la'ititi la'ititi o la'au o le valve
Tete'e o le Temperature: Ea lemu: -200 tikeri i le +500 tikeri ; si'osi'omaga fa'ama'i: fautuaina E itiiti ifo pe tutusa ma +400 tikeri /+450 tikeri; leai se liusuavai, fa'ama'a'a pe fa'aleagaina
Lubrication -tagata: Graphite (lubricant malo) e fa'aitiitia ai fe'ese'esea'i o le a'au o le valve & fa'agaoioiga; fa'amautinoa le fa'agaioiina lelei, puipuia le a'a o le valve mai le ofuina
Vailaau Fa'ainisinia: Fa'asao maualuga i vaila'au eseese, alkalis, solvents, fa'alapotopotoga fa'aola; talafeagai mo faiga kemisi pala
Fa'apipi'i: Fa'a'au'au fa'a'au'au ma le maualuga fetuutuuna'i & faigata; faigofie ona afifi auga valve, ogatasi ma pusa pusa geometry; leai ni meafaigaluega fa'apitoa e mana'omia
Ola Au'aunaga: Anti-matua, ete'e i ta'amilosaga vevela & te'i mamafa; fa'aitiitia le taimi fa'aleleia, fa'asolo taimi ma le tau atoa o le pule
3. Talosaga Autu
Fa'aaogaina lautele i alalaupapa fa'apisinisi e mana'omia ai fa'amaufa'ailoga fa'atuatuaina, e aofia ai ae le fa'atapula'aina i:
Chemical & Petrochemical: Valves (faitotoa, kelope, polo, fa'atonutonu) i reactors, paipa, pamu
Gausia le Malosiaga: Feula -valau, alavai faiga ausa i fale eletise
Pharmaceutical & Food: Valves mo le tumama-fa'aoga taua
Metallurgical: Valau -vevela maualuga, kasa
Pepa: Fa'agasologa alavai e fa'aogaina vaila'au fa'a'a'a
