1.Top ituaiga ulufale polo valve i le paipa e faigofie ma vave talepe, faia tausiga faigofie.
2. O le valve polo ma le tino faʻapipiʻi atoatoa e mafai ona tanumia saʻo i le eleele, ina ia le faʻaleagaina vaega i totonu o le valve, o le ola tautua e oʻo atu i le 30 tausaga, o le valve lelei mo paipa suauu ma kesi masani.
3. Faʻamaufaʻailoga atoatoa e mafai ona ausia i luga o le tele o faʻalavelave ma vevela.
4.O le auala galue e faʻamaufaʻailogaina faʻalagolago i itu uma e lua.
O valve polo pito i luga e masani ona faʻaaogaina i faiga faʻagasologa e sili ona lelei le tausiga ile laina nai lo le aveeseina atoa o le valve. I le taimi o le tausiga, naʻo le tatalaina o le ufiufi e sii ai le polo ma le tino lagolago e aunoa ma le aveeseina o le valve atoa mai le paipa, faʻafaigofie le tausiga. .I taimi faʻapitoa, e le mafai e le pito i luga-ulufale polo valves ona aʻafia ai le faʻaogaina masani o le pipeline system i le taimi o le toe faʻaleleia vave, pe afai e aveese vave le polo ma le nofoa faʻapotopotoga pe a uma ona faʻamaufaʻailoga le ufiufi valve, o le pipeline system with pressure operation e mafai. ia toe faʻaleleia vave, ina ia faʻaitiitia le gau e mafua mai i le toe faʻaleleia vave. E masani ona faʻaaogaina mo meaʻai, vailaʻau, suauʻu, kesi masani, vailaʻau, eletise eletise, metallurgy, puipuiga o le siosiomaga, fausiaina o taulaga, fai pepa ( ala e pei ole ea, vai, suauu, hydrocarbon, sua oona).
