Fa'apipi'i le alatoto polo e ulufale i le itu
Autu: O le polo e faʻapipiʻiina i luga ma lalo o le pu, o lea e le gafatia e mama nofoa le tele o le malosi o le tafe pe a tapunia le valve. I lalo o le mamafa o le tafe, o le mama nofoa e opeopea teisi i le polo ma fausia ai se faʻamaufaʻamau. Laiti fa'agaioiga torque, fa'aletonu laiti i luga o nofoa, fa'amaufa'ailoga fa'atuatuaina fa'atinoga, ola umi o le tautua o le fa'amanuiaga autu lea o le valve polo fa'apipi'i. Trunnion fa'apipi'i polo valve o lo'o fa'aaogaina lautele i paipa mamao ma paipa masani fale gaosi oloa e mafai ona tatalia ituaiga eseese o tafega pala po'o noncorrosive.
