Faʻatasi ai ma fua e amata mai i le DN50 i le DN600, o la matou oloa e lava le tele e fetaui ma le tele o faʻaoga, faʻamautinoaina se fetaui lelei mo ou manaʻoga faʻapitoa. I le fatu o Sansheng Fluorine Plastics 'faʻafouina o loʻo taoto ai la matou tautinoga i le leai o se leakage faatinoga. O le Nofoa Valve Fa'apipi'i Fa'atasi ua mamanuina e tu'uina atu ai se pa puipui e le mafai ona fa'asaga i le liki, fa'amautinoa o lo'o sologa lelei ma lelei au gaioiga. O lenei tulaga o le fa'atuatuaina e taua tele i alamanuia lea e o'o lava i le la'ititi la'ititi e mafai ona o'o atu ai i le tele o gau po'o le saogalemu. E ala i le filifilia o matou PTFE valve nofoa, e te le na o tupe teu i se oloa; o lo'o e teu fa'afaigaluega i le filemu o le mafaufau, ma le iloa o au galuega e puipuia e le sili i le pisinisi.
O la matou tautinoga i le tulaga lelei ma le tulaga lelei o loʻo faʻaalia atili e ala ia matou suʻega faigata ma faiga faʻamautinoaga lelei. E faia su'esu'ega tetele ta'itasi o Nofoa Valve Fa'apipi'i e fa'amautinoa e fetaui ma a tatou tulaga maualuga mo le fa'atinoga ma le tumau. O lenei gauai totoʻa i auiliiliga e faʻamautinoa ai e te mauaina se oloa e mafai ona tatalia le faigata o lau talosaga, tuʻuina atu faifai pea, faʻalagolago i le taimi. Fuafuaina mo i latou o loʻo manaʻomia le mea sili, o la matou oloa e ofoina atu se tuʻufaʻatasiga o vailaʻau faʻamaʻi, mea faʻamalama ma eletise eletise, ma leai se faʻaogaina o gaioiga e le faʻatusalia i le maketi. Pe o oe i le vailaʻau, vailaʻau, poʻo soʻo se isi pisinisi e manaʻomia le maualuga o le faʻatinoga mai ou nofoa valve, o la matou oloa o le fofo lea o loʻo e sailia. Fa'atuatuaina le Sansheng Fluorine Plastics e fa'atumauina au fa'agaioiga e sologa lelei ma lelei, tusa lava po'o a lu'itau e te feagai.

Zero Leakage PTFE Valve Nofo Butterfly Valve Vaega DN50 - DN600
Taupou PTFE (Polytetrafluoroethylene)
PTFE (Teflon) o le fluorocarbon faʻavae polymer ma e masani lava o le sili ona faʻamaʻi faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻamalama ma eletise eletise. O le PTFE e iai foʻi le maualalo o le feteʻenaʻiga o lea e lelei mo le tele o faʻaoga maualalo.
O mea nei e le fa'aleaga ma talia e le FDA mo mea'ai. E ui lava o mea faʻainisinia o le PTFE e maualalo, faʻatusatusa i isi palasitika faʻainisinia, e tumau pea lona aoga i luga o le lautele o le vevela.
