1. O le polo pupuni lapotopoto e faʻaaogaina e fai ma vaega tatala ma tapuni, ma o le valve stem ball e faʻataʻamilo i le laina ogatotonu o le tino valve e iloa ai le tatalaina ma le tapunia o le valve.
2. Fa'apipi'i ma talafeagai le fa'atulagaina, la'ititi avanoa avanoa o le valve tino, fa'aitiitia le fa'atumauina. Fa'aaogaina o faiga fa'apitoa, ina ia sili atu le maualuga o le fa'amaufa'ailoga, fa'atasi ai ma V PTFE fa'apipi'i tu'ufa'atasiga, ina ia maua ai e le valve le leakage.
3. O le polo o le tatalaina ma le tapunia o vaega ma le valve o loʻo tuʻuina e pei o le tasi, e faʻaumatia ai le avanoa o le valve stem i fafo atu o vaega faʻapipiʻi e mafua mai i suiga o le mamafa, ma faʻamautinoa le saogalemu o le faʻaaogaina i le poloketi.
4.PFA/FEP lining, ma le mautu vailaau maualuga, e mafai ona faʻaaogaina i soʻo se isi faʻasalalauga faʻamalosi malosi sei vagana ai "umea alkali faʻafefe ma elemene fluorine".
5. Faʻaaogaina le lautele atoa, fausaga polo opeopea. O valve e fa'agata ai liki i le vaega o le mamafa mo le saluina lelei o polo ma le tausiga o laina.
Fuafuaga faʻapolofesa ma pusa vaʻaia fluorine laina faʻapipiʻi polo valve pulea le tele o ala o faasalalauga corrosive malosi, faʻaaogaina lautele i le suauu, vailaʻau, vailaau faʻasaina, vali, vailaʻau gaosi oloa ma alkali, o le valve anticorrosive sili ona lelei.
