I le malo o vaega o valve alamanuia, o le ausiaina o faʻamaufaʻailoga sili ona lelei ma le faʻaogaina lelei e sili ona taua. Sansheng Fluorine Plastics o loʻo tu i luma o lenei fanua, faʻapitoa i le gaosiga o mama faʻamaufaʻailoga afi EPDM PTFE maualuga, ua fuafuaina e faʻafeiloaʻi ma sili atu i manaʻoga faʻapitoa o faʻaoga faʻaonaponei. O la matou tautinoga i le tulaga lelei o loʻo faʻaalia i le faʻatinoga le mafaatusalia a matou oloa, faʻapipiʻiina tulaga-o-le-mea faʻataʻitaʻi ma mea faʻatekonolosi faʻapitoa e faʻamautinoa ai le sili atu le tumau ma le leai o se faʻaogaina.
O le totonugalemu o la matou laina oloa, o le EPDM PTFE butterfly valve sealing ring, o loʻo faʻainisinia ma le totoa mai le taupou PTFE (Polytetrafluoroethylene), taʻutaʻua ona o le faʻaogaina o vailaʻau faʻapitoa ma le mataʻina o le vevela ma le eletise. O le mea lea ua avea ai a tatou mama fa'amaufa'ailoga ma filifiliga lelei mo le tele o fa'aoga, mai le gaosiga o vaila'au i le gaosiga o mea'ai ma meainu. O le faʻafefiloi faʻapitoa o le EPDM ma le PTFE e le gata ina faʻaleleia ai le faʻamaʻiina o vailaʻau ae faʻateleina foi le fetuutuunai ma le maufetuunaʻi o le mama faʻamaufaʻailoga, faʻamautinoaina se faʻamaufaʻailoga faʻamau, leak-faʻamaufaʻailoga e oʻo lava i lalo o tulaga sili ona luʻitau. , o matou EPDM PTFE butterfly valve faʻamaufaʻailoga mama o loʻo maua i le tele o lapopoa, mai le DN50 i le DN600, i le fa'aogaina le tele o valve ma mana'oga fa'atino. O mama fa'amau ta'itasi e fa'atatau i siaki fa'atonutonu lelei, fa'amautinoaina o oloa uma e tu'uina atu ia tatou tagata fa'atau e fetaui ma tulaga maualuga o le fa'atuatuaina ma le fa'atinoga. Pe o e faʻaleleia vaega valve o loʻo i ai nei poʻo le faʻatinoina o mea fou, o matou EPDM PTFE faʻamaufaʻailoga mama e ofoina atu le faʻafefiloi atoatoa o mea fou, lelei, ma le faʻamaoni, faʻatulagaina faʻailoga fou i le alamanuia mo le faʻamauina lelei.

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.
