Valve Butterfly Premium ma Nofo Teflon - Sansheng Fluorine Plastics
I totonu o le fatu o le faʻatonutonuina o le suavai, o le faʻamaoni ma le faʻamaoni o vaega o le valve e taua tele i le faʻatinoga lelei. O le Sansheng Fluorine Plastics o lo'o fa'ailoa mai lana oloa fa'atau - le Butterfly Valve with Teflon Seat, o se maatulimanu i le ausiaina o le leai o se li'o i le tele o fa'aoga. O a matou Teflon (PTFE) o loʻo nofoia valve butterfly ua maeʻa faʻainisinia e faʻafetaui manaoga manaʻomia o le DN50 i le DN600 lapopoa laina, faʻamautinoaina le fetaui lelei mo faʻapipiʻi masani ma faʻapipiʻi.
Fausia mai Virgin PTFE (Polytetrafluoroethylene), o nei nofoa valve butterfly e le o ni mea masani. O le PTFE, e ta'uta'ua ona o le mata'ina o lona tete'e atu i vaila'au, o lo'o tu i luga o le fa'atekonolosi polymer, fa'amautinoaina e mafai e a tatou va'a ona tatalia vaila'au sili ona leaga e aunoa ma se fa'aletonu. O lenei mea mataʻina, e masani ona fesoʻotaʻi ma le ituaiga Teflon, e ofoina atu le faʻamautuina o le vevela ma le eletise eletise, ma avea ai ma filifiliga lelei mo le tele o fale gaosi oloa. Pe o le pharmaceutical, kemikolo, po o meaai ma meainu alamanuia, o lo tatou butterfly valve ma Teflon nofoa ua mamanuina e tuuina atu faatinoga sili atu, faamautinoa se contaminant-le siosiomaga saoloto ma lamolemole faagaoioia flow.Moreover, o le mamanu fou o tatou PTFE Valve Seat Butterfly Valve Vaega siamupini le mataupu faavae o le leai-leakage. E le naʻo se tagi ae o se faʻamaoniga faʻapitoa, faʻafetai i meatotino faʻapitoa a le PTFE ma a matou auala faʻapitoa gaosiga. O le mamanu lavelave e faʻamautinoaina ai se faʻamaufaʻailoga mau, puipuia soʻo se mea e ono tafe ma faʻamautinoa le faʻatinoina o le amio saʻo. O le fegalegaleai oa tatou nofoa o le butterfly valve o lona uiga e le gata ina talafeagai mo le puleaina o le tafe o le suavai ae faapea foi kesi, ma avea ai ma se filifiliga tele mo talosaga eseese i pisinisi. Faatasi ai ma le tautinoga a le Sansheng Fluorine Plastics i le tulaga lelei, o lenei valve butterfly ma le nofoa Teflon o se molimau i lo matou tuuto i le saunia o fofo e faʻaleleia ai le lelei, saogalemu, ma le faʻamaoni i au gaioiga.

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.
Va'aiga vevela: -38°C i le +230°C.
