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.
Vevelation stress: - 38 ° C i + 230 ° C.
Lanu: paepae
Fa'aopoopo fa'asili: 0%
Tulaga tau Laupapa:
| Mea | Talafeagai Temp. | Uiga |
| NBR |

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. |

Tulaga lelei:
O le PTFE e tu mo PolyTetraFluoroEthylene, o le faaupuga vailaʻau mo le polymer (CF2)n.
Polytetrafluoroethylene (PTFE) o se sui thermoplastic o le fluoropolymer aiga o palasitika ma e maualalo le coefficient o feteʻenaʻiga, mea lelei insulating.
PTFE e chemically inert i le tele o mea. E mafai fo'i ona tatalia fa'aoga vevela maualuga ma e iloa lelei mo ana mea fa'aanti-stick.
Filifilia o le nofoa nofoa taumatau mea o le tele o faigata o filifiliga i Valve Polo Filifiliga. Ina ia fesoasoani i a matou tagata faʻatau i le taimi o lenei faiga, matou te naunau e ofoina faʻamatalaga i luga o tagata faʻatau talosaga.
PTFE valve nofoa na gaosia e le US o loʻo faʻaaogaina lautele i textile, eletise eletise, petrochemical, faʻamafanafana ma pusaaisa, vailaʻau, fau vaa, metallurgy, alamanuia mama, puipuiga o le siosiomaga, Alamanuia Pepa, Sugar Industry, Compressed Air ma isi fanua.
Fa'atinoga o oloa: maualuga le vevela, malosi lelei ma le alkali ma le suauu; fa'atasi ai ma le toe fa'aleleia lelei, malosi ma tumau e aunoa ma le tafe.
O le tulaga ese o le prelgamution o ptfe ma epdm mea i totonu o tatou alatoto dats ofoina atu se tuʻufaʻatasiga o le vailaʻau ma le tumau.
