Black/ Green PTFE/ FPM + EPDM Rubber Valve Nofo mo Butterfly Valve Nofo
PTFE + EPDM faʻapipiʻiina nofoa valve paʻu gaosia e SML o loʻo faʻaaogaina lautele i le ie, eletise, petrochemical, faʻamafanafana ma le pusaaisa, vailaʻau, fau vaa, metallurgy, alamanuia mama, puipuiga o le siosiomaga ma isi fanua.
Fa'atinoga o oloa: maualuga le vevela, malosi lelei ma le alkali ma le suau'u; fa'atasi ai ma le toe fa'aleleia lelei, malosi ma tumau e aunoa ma le tafe.
PTFE+EPDM
O le liner Teflon (PTFE) e ufiufi ai le EPDM lea e fa'apipi'i i se mama phenolic malo i luga o le pito nofoa pito i fafo. O le PTFE e faʻalautele i luga o le nofoa faʻailoga ma fafo o le faʻamaufaʻailoga faʻamaufaʻailoga, e ufiufi atoa ai le EPDM elastomer layer o le nofoa, lea e maua ai le maufetuunaʻi mo le faʻamaufaʻailoga valve stems ma le tapuni tapuni.
Va'aiga vevela: -10°C i le 150°C.
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.
Lanu: paepae
Fa'aopoopo fa'asili: 0%

O le fatu o la tatou oloa o loʻo taoto i lona feʻaveaʻi ma le fetuutuunai. O le Wafer Type Centerline Soft Sealing Butterfly Valve ma le pneumatic Wafer Butterfly Valve, e lagolagoina uma e lua wafer ma flange fesoʻotaʻiga, ua mamanuina e faʻapipiʻi faʻatasi ma faiga o loʻo i ai, faʻaitiitia le manaʻomia mo suiga tetele poʻo suiga. O le valve butterfly, e iloga ona fa'ailogaina i lona lug type double half shaft e aunoa ma se pine, fa'amautinoaina se feso'ota'iga mautu ma malosi, fa'aitiitia le lamatiaga o le leaka ma fa'aleleia le saogalemu o galuega. E le gata i lea, o le tuufaatasiga o le uliuli / lanumeamata PTFE ma le FPM + EPDM paʻu i totonu o le nofoa valve e le gata ina fesoasoani i lona manaia matagofie ae faʻamalosia ai foi lona malosi ma le teteʻe i le ofuina ma loimata, ma faʻalauteleina ai le ola o le valve ma le tele. , o la matou tautinoga i le tulaga lelei o loʻo atagia mai i le faʻataʻitaʻiina ma le faʻagasologa o gaosiga o matou nofoa faʻafefete faʻafefete. E ala i le usita'ia o faiga fa'atonutonu lelei ma le fa'aogaina o mea aupito sili ona lata mai i mea fa'asaienisi, matou te fa'amautinoaina o oloa ta'itasi o lo'o alia'e mai le matou fale e fa'atino ai lo matou tu'ufa'atasiga i le lelei, fa'afouga, ma le fa'amalieina o tagata fa'atau. Pe faʻapipiʻiina i totonu o le siosiomaga o lafoga o se fale gaosi oloa, o se eletise malosi, poʻo auala taua o se fale petrochemical, o matou nofoa valve e tu o se faʻamaoniga o lo matou tomai i le fatuina o fofo e le gata ina fetaui ae sili atu i faʻamoemoega o le lalolagi. .
