Premium EPDM + PTFE Butterfly Valve Nofo - Sansheng Fluorine Plastics
I totonu o le malo o faʻaoga valve alamanuia, o le faʻamaoni ma le faʻatinoina o le nofoa valve e sili ona taua mo le faʻamautinoaina o le faʻamaoni ma le lelei o le faagasologa. O le Sansheng Fluorine Plastics o lo'o fa'alauiloaina lana oloa fa'atau, le EPDM + PTFE Butterfly Valve Seat, e avea o se vaifofo paionia ua fuafuaina e fa'amalieina mana'oga faigata o le tele o fa'atonuga o le vai. O lenei oloa o loʻo faʻatusalia ai le tuʻufaʻatasia o mea faʻapitoa e lua: ethylene propylene diene monomer (EPDM) ma polytetrafluoroethylene (PTFE), e lauiloa foʻi e lona igoa igoa, Teflon. Faʻatasi, latou te fausia se nofoa valve e faʻaalia ai mea e le mafaatusalia i tulaga o le teteʻeina o vailaʻau, tumau, ma le faʻatuatuaina o le faʻaogaina i luga o le tele o fusi o le vevela ma le mamafa.
O la matou EPDM+PTFE Butterfly Valve Seat ua fa'ainisinia e fa'amalieina le tele o ta'ita'i mai le DN50 i le DN600, ma avea ai ma filifiliga sili mo le tele o paipa ma fa'ata'ita'iga fa'atonutonu vai. O le 'autu o la tatou oloa o lo'o taoto i lona fa'aogaina fou ole PTFE taupou, o le fluorocarbon-fa'avae polymer e ta'uta'ua mo lona fa'a'ese'esega fa'ama'i uma. O lenei mea e le tali atu i le tele o vailaʻau faʻapisinisi, acids, poʻo solvents, ma avea ai o tatou nofoa valve o se filifiliga lelei mo talosaga e aofia ai sua pala. E le gata i lea, o le maualuga o le vevela o le PTFE ma le maualalo o le faʻafefeteina o le feteʻenaʻiga e saofagā i le faʻaogaina o le valve ma le umi o le ola, e oʻo lava i lalo ole tulaga maualuga - vevela. ma leai se li'o fa'atinoga i lalo o suiga eseese o le mamafa ma le vevela. O le fesoʻotaʻiga i le va o le EPDM ma le PTFE i totonu o matou nofoa valve butterfly e le gata ina faʻaleleia ai a latou vailaʻau ma vevela ae faʻaleleia ai foʻi o latou ofuina ma loimata, faʻalauteleina le umi o le faʻaogaina o le faʻapotopotoga valve. Fuafuaina ma le sa'o ma gaosia e tusa ai ma tulaga aupito maualuga o alamanuia, o le Sansheng Fluorine Plastics 'EPDM + PTFE Butterfly Valve Seat e tu e fai ma molimau i le faʻafouina i tekonolosi faʻatonutonu vai, faʻaalia le faʻamaoni, lelei, ma le le mafaatusalia faʻatinoga mo au talosaga taua.

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.
