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.
