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 faʻamaʻiina faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻavela ma 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 a matou fa'amaufa'ailoga a le pepe pepe o le pito sili lea o la matou laina oloa, ua fuafuaina mo le fa'aogaina i le tele o talosaga e aofia ai vai, suau'u, kesi, suau'u fa'avae, ma e o'o lava i fa'asalalauga acidic. O lo'o fa'atulagaina fa'apitoa e fa'amalieina si'osi'omaga maualuga-vevela, fa'amautinoa o lo'o tumau pea au fa'agaioiga e le motusia ma lelei, tusa lava po'o le a le lu'itau o lo'o i ai. Faatasi ai ma lapopoa e amata mai i le DN50 i le DN600, o tatou faʻamaufaʻailoga e tele ma e mafai ona tuʻufaʻatasia i totonu o ituaiga valve eseese e aofia ai vaʻavaʻa faʻamaufaʻailoga ogatotonu faʻamaufaʻailoga mama valves ma pneumatic wafer butterfly valves, faʻapea foʻi ma le lug type double half shaft butterfly valves e aunoa ma se pine. tulaga maualuga galuega, o nei faamaufaailoga o se molimau i le tautinoga a Sansheng Fluorine Plastics i le lelei ma le faatumauina. Faʻaaogaina o se faiga faʻapipiʻi tulaga ese e faʻafefiloi ai le faʻaogaina o vailaʻau e le mafaatusalia o le PTFE ma le elasticity ma le tumau o le EPDM, o nei faʻamaufaʻailoga e sili atu i tulaga faʻapisinisi mo le faʻatinoga, umi, ma le saogalemu. Latou te maua lo latou nofoaga i pisinisi taua e pei o ie, nofoaga eletise, faʻaogaina o le petrochemical, faʻamafanafana ma le pusaaisa, vailaʻau, fau vaa, metallurgy, alamanuia mama, ma le puipuiga o le siosiomaga, faʻaalia o latou agavaʻa ma lautele lautele lautele. Fa'atasi ai ma a matou fa'amaufa'ailoga a le pepe pepe, e le na'o le fa'atauina o se oloa; o lo'o e teu fa'afaigaluega i le filemu o le mafaufau, ma le iloa o au galuega ua fa'amaufa'ailogaina ma le lelei.
