Premium Keystone PTFE+EPDM Butterfly Valve Nofo mo Alamanuia
I le lalolagi malosi o le pulea o le vai ma le tekinolosi valve, o le Keystone PTFE + EPDM butterfly valve seat e tulaʻi mai o se faʻataʻitaʻiga o le faʻamaoni ma le lelei. I Sansheng Fluorine Plastics, matou te fa'apitoa i le tu'uina o tulaga - o-le-nofoa valve fa'ata'ita'i o se fa'ata'ita'iga o le fa'ainisinia sa'o. O loʻo faʻapipiʻiina i le maufetuunaʻi o le Virgin PTFE (Polytetrafluoroethylene) ma le fetuutuunai o le EPDM (Ethylene Propylene Diene Monomer) paʻu, o tatou nofoa valve butterfly o loʻo tu i le pito i luma o le tulaga lelei o pisinisi.
O le tu'ufa'atasiga tulaga ese o meafaitino PTFE ma EPDM i totonu oa tatou nofoa valve e ofoina atu ai se tuufaatasiga e le mafaatusalia o vailaʻau tetee ma le tumau. O le PTFE, e masani ona taʻua o Teflon, ua faʻamanatuina ona o lona teteʻe atu i le toetoe lava o vailaʻau faʻapisinisi uma, ma avea ai ma filifiliga lelei mo siosiomaga faigata. O lenei polymer fa'avae fluorocarbon-o lo'o fa'atumauina le fa'amautu lelei o le vevela ma mea fa'a'ese'ese eletise, fa'amautinoaina le fa'atinoina lelei o nofoa alatoto i lalo o tulaga ogaoga. O le faʻapipiʻiina o lenei mea, e faʻaleleia ai e le paʻu EPDM le faʻaleleia o le nofoa mai le ofuina ma loimata, tuʻuina atu se vaega faaopoopo o le puipuiga ma faʻalauteleina le ola o le valve.O matou Keystone PTFE + EPDM butterfly valve seat ua mamanuina e faʻafeiloaʻi ai le tele o talosaga, mai le DN50 i le DN600 lapoa, faʻamautinoaina le fetaui lelei mo le tele o laina paipa. O le leai o se leakage o tatou nofoa valve ua iloga ai le alualu i luma tele i tekinolosi fa'atonutonu vai, ma maua ai le filemu o le mafaufau ma le fa'atuatuaina i fale gaosi oloa. Pe mo vai vai, fale gaosi vaila'au, po'o HVAC system, o tatou nofoa valve e fa'amautinoaina se masini e pulea lelei ma lelei le tafe. Tofo i le tumutumu o le nofoa valve mamanu ma le Sansheng Fluorine Plastics, lea e fetaui lelei ai mea fou.

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.

O le pa'u nitrile e lelei lona lava - fa'alauteleina meatotino, abrasion tete'e ma hydrocarbon - mea e tete'e. E mafai ona faʻaaogaina e avea o se mea lautele mo vai, vacuum, acid, masima, alkali, gaʻo, suauu, pata, suauʻu hydraulic, glycol, ma isi. E le mafai ona faʻaaogaina i nofoaga e pei o le acetone, ketone, nitrate, ma fluorinated hydrocarbons. |
